Title: Observations of Solar Global Oscillations 1983-1985 and
    Potential Influence of Terrestrial Sources of Errors
Authors: Severny, A. B.; Kotov, V. A.; Tsap, T. T.
Bibcode: 1988IAUS..123...33S
Altcode:
  The Earth atmospheric pressure fluctuations in the 5-min range of
  periods are analysed and their influence on observations of solar
  5-min oscillations are briefly discussed. New series of observations
  confirmed the oscillations of the Sun with period of 160.010 min.

Title: On the Ultraviolet Background Radiation of the Galaxy
Authors: Zvereva, A.; Severny, A.; Granitsky, L.; Courtes, G.;
   Cruvellier, P.; Hua, C. T.
Bibcode: 1985IAUS..106..237Z
Altcode:
  Observations of the far-UV spectrum (1300 - 1800 Å) of the sky
  background at different galactic latitudes are presented. The
  measurements were made with the photoelectric spectrometer
  ("Galaktika") on board the "Prognoz-6" satellite. The highly
  elongated orbit of the satellite permitted corrections for scattered
  L<SUB>&amp;</SUB>alpha;-light. The contribution of stars was eliminated
  using fluxes measured in the TD-I and OAO-2 experiments.

Title: Photometric calibration and first results obtained with the
    UFT experiment on board the astron satellite
Authors: Hua, C. T.; Courtes, G.; Cruvellier, P.; Huguenin, D.;

  The UV telescope of 30 cm diameter equipped with a three channel scanner
  spectrometer aboard the highly eccentric orbit space station ``ASTRON''
  is described <P />Absolute calibration of the whole device is performed
  using spectra of standard stars, of which absolute values were obtained
  by TDI or IUE experiments. Several photometric controls have been
  made on the stability of the equipment after one year of operation
  which demonstrate reliability of some first results obtained by the
  UFT. <P />The sensitivity curve of the spectrophotometric system has
  been observed with a reproducibility of 2σ = 10% or better. <P />The
  repeated observation of one star (139 Tau) indicates that the overall
  performance exhibits the same quality after one year in orbit. The low
  resolution mode (Δ λ = 28 Å) leads to a powerful new investigation
  of faint extended sources.

Title: Ten years observations of long-period oscillations of the Sun
Authors: Kotov, V. A.; Severny, A. B.; Tsap, T. T.
Bibcode: 1984ESASP.220..189K
Altcode: 1984ESPM....4..189K
  The measurements of Doppler shift of a Fraunhofer spectral line were
  performed over 10 yr. The power spectrum of the data shows a major peak
  at 160m period which is interpreted as multiple resonance of gravity
  modes of the Sun. This 160m oscillation reveals remarkable phase
  stability during the entire decade. It is noted that true pattern
  of the power spectrum can be seriously spoiled by Earth sources of
  noise. The importance of analysis of oscillations seen in a telluric
  line is emphasized.

Title: On the Excitation of Oscillations of the Sun - Numerical Models
Authors: Kosovichev, A. G.; Severny, A. B.
Bibcode: 1983SoPh...82..323K
Altcode: 1983IAUCo..66..323K
  Numerical solutions of the general time-dependent gas-dynamical
  equations in linear adiabatic approximation are given for initial
  conditions imitating: (a) a central perturbation, (b) a boundary
  perturbation (in the convective envelope), and (c) a `shrinking' of
  the Sun as a whole. For a variety of models of the Sun it is found
  that at the surface the radial component v<SUB>r</SUB> of velocity is
  much greater than the tangential component v<SUB>t</SUB>, and that the
  period T of stationary oscillations does not exceed 131<SUP>m</SUP>. The
  appearance at the surface of a g mode with period 160<SUP>m</SUP>
  is found to be improbable.

Title: A Possible Interpretation of the Ultraviolet Sky Back-Ground
    Radiation Observed with the Space Experiment "Galaktika"
Authors: Severny, A. B.; Zvereva, A. M.
Bibcode: 1983ApL....23...71S
Altcode:
  Measurements made in deep space of the intensity of ultraviolet sky
  background radiation, in the range of latitudes -58 deg to +27 deg,
  show a correlation between that intensity and enhanced soft X-ray
  brightness, and also with deficient neutral hydrogen density. A
  pronounced decrease in intensity from 1400 to 1800 A is apparent in
  dark, higher latitude regions in Pisces, while a rapid increase in
  intensity over that range is observed in low galactic latitudes. A
  coincidence in position between radio spurs and several regions of
  ultraviolet emission is also noted. A possible explanation of background
  ultraviolet radiation in high-latitude areas as emission from the hot
  gas of supernova remnants is discussed.

Title: Solar oscillations and the problem of the internal structure
    of the sun
Authors: Severny, A. B.; Kotov, V. A.; Tsap, T. T.
Bibcode: 1979AZh....56.1137S
Altcode:
  Observations of solar oscillations made over a period of five years
  are reviewed, and implications of the observations for the physics
  of the solar interior are indicated. An analysis of over 1000 hours
  of solar observations from 1974 to 1978 is presented which shows the
  observed oscillations of the solar radius to be real, with a period of
  160.010 + or - 0.004 min and a Doppler shift amplitude of 1 m/sec. The
  slow drift of the phase of the velocity maximum has been observed,
  together with the dependence of the amplitude on the phase of the
  solar rotation period. Synchronous oscillations of the solar magnetic
  field and radio emission have also been found to be synchronous to
  the brightness oscillations, and the oscillations have been seen to
  disappear occasionally, possibly due to the passage of a supergranule
  across the solar disk. It is suggested that the oscillations represent
  gravitational quadrupole oscillations, and could serve as a means for
  nonradiative heat transfer from within the sun and thus alleviate the
  problem of low neutrino flux.

Title: Soviet short-term forecasts of active region evolution and
    flare activity
Authors: Severny, A. B.; Stepanyan, N. N.; Steshenko, N. V.
Bibcode: 1979stp.....1...72S
Altcode:
  The structure and strength of the magnetic fields of the Sun's
  active regions were studied to obtain information for short term
  forecasting. Intensity forecasts were then made using the information
  obtained on the gradients of the magnetic fields between sunspots
  of opposite polarity. A comparison of flare forecasting methods is
  presented.

Title: Observations of solar oscillations with periods of 160 minutes
Authors: Scherrer, P. H.; Wilcox, J. M.; Kotov, V. A.; Severny, A. B.;
   Tsap, T. T.
Bibcode: 1979Natur.277..635S
Altcode:
  Severny et al. (1976) have reported oscillations of the sun with
  a period near 160 min. A description is presented of observations
  made at the Stanford Solar Observatory during the time from 1975 to
  the present which seem to support the reports by Severny et al. At
  Stanford the relative velocity between a central circular area of
  radius 0.5 solar radius on the solar disk and most of the remaining
  area of the solar disk is measured. A superposed epoch analysis of
  the observations using a period of 160 min is discussed. An apparent
  agreement in phase between the obtained observational data and those
  reported by Severny et al. tends to support the interpretation that
  solar oscillations are being observed.

Bibcode: 1977AcAau...4.1121B
Altcode:
  The orbiting solar telescope on Salyut-4 (F = 2.5 m, d = 250 mm)
  produces images of the sun on the entrance slit of a stigmatic
  two-grating spectrograph (R<SUB>1</SUB> = 1 m, N<SUB>1</SUB> =
  1200 lines/mm; R<SUB>2</SUB> = 0.5 m, N<SUB>2</SUB> = 2400 lines/mm,
  dispersion 16 A/mm, spectral resolution 0.3 A). The automatic system
  keeps the observed solar features on the slit of the spectrograph with
  an accuracy of 3-4 arc sec. The far UV-spectra (970-1400 A) of solar
  flares, brightenings, flocculi and prominences were photographed and
  fresh coatings of mirrors were made during the flight.

Title: The mean magnetic field of the Sun: Method of observation
    and relation to the interplanetary magnetic field
Authors: Scherrer, Philip H.; Wilcox, John M.; Kotov, Valeri; Severny,
   A. B.; Howard, Robert
Bibcode: 1977SoPh...52D...6S
Altcode:
  The mean solar magnetic field as measured in integrated light has
  been observed since 1968. Since 1970 it has been observed both at
  Hale Observatories and at the Crimean Astrophysical Observatory. The
  observing procedures at both observatories and their implications for
  mean field measurements are discussed. A comparison of the two sets
  of daily observations shows that similar results are obtained at both
  observatories. A comparison of the mean field with the interplanetary
  magnetic polarity shows that the IMF sector structure has the same
  pattern as the mean field polarity.

Title: Transit of Mercury across the solar disk
Authors: Efanov, V. A.; Moiseev, I. G.; Severny, A. B.
Bibcode: 1974Natur.249..330E
Altcode:
  THE transit of Mercury across the solar disk on May 9, 1970 (4 h
  20 min 30 s - 11 h 12 min 0 s UT), was observed by recording the
  radio emission at a wavelength of 8 mm using a 22-m paraboloid radio
  telescope<SUP>1</SUP>. The pencil beam of the antenna is of width D
  = 1'.6 and the sensitivity of the radiometer ~= 1.5 K. The antenna
  was steered so that Mercury was in the centre of the beam. Mercury
  obscures the inhomogeneities of radio emission when passing across
  the solar disk and some fluctuations of the flux of radio emission
  can occur. The characteristic time of these fluctuations and their
  amplitude characterise the sizes and temperatures of condensations
  respectively. In Fig. 1 we show a sample of original (averaged over
  15 s) records of fluctuations during the passage of Mercury across
  the relatively active regions on the disk. Similar records, but with
  slightly slower fluctuations of smaller amplitude have been obtained for
  quiet regions of the disk. The autocorrelation curves for active (A) and
  quiet (Q) regions (Fig. 2) reveal details of the nature of the emission.

Title: The Comparison of the Magnetographic Magnetic Field Measured
    in Different Spectral Lines
Authors: Gopasyuk, S. I.; Kotov, V. A.; Severny, A. B.; Tsap, T. T.
Bibcode: 1973SoPh...31..307G
Altcode:
  The discrepancies in the values of longitudinal magnetic field
  obtained from magnetographic records in different spectral lines
  are considered. On the basis of extensive data including 60 pairs of
  magnetographic maps for 11 spectral lines, obtained simultaneously
  for one of these lines and λ6103 with the aid of the Crimean double
  channel magnetograph, the following conclusions have been reached. The
  relative field strength (6103) depends partly on the distance from the
  center of the disk (Figure 4) and mainly on the magnetic sensitivity
  of the line gλ<SUP>2</SUP> (Figure 3), pointing to the primary role
  of saturation effect. The possible influence of line asymmetry on
  these discrepancies is also suggested.

Title: On the Circular Polarization of Some Peculiar Objects
Authors: Nikulin, N. S.; Kuvshinov, V. M.; Severny, A. B.
Bibcode: 1971ApJ...170L..53N
Altcode:
  Circular polarization of several peculiar objects (in particular, X-ray
  sources) has been measured with the stellar magnetograph of the 104-inch
  Crimean reflecting telescope. Circular polarization greater than or
  equal to 1 percent is suspected in the nuclei of the Seyfert galaxies
  NGC 4151 and NGC 1068, and in the quasar SC 273. Rapid variations
  of the amount and sense of circular polarization are observed in the
  X-ray source Sco X-1 with time scales of the order of 30 minutes. An
  appreciable effect is also detected in the nucleus of the planetary
  nebula +3003639.

Title: Comparison of the Mean Photospheric Magnetic Field and the
    Interplanetary Magnetic Field
Authors: Severny, A.; Wilcox, J. M.; Scherrer, P. H.; Colburn, D. S.
Bibcode: 1970SoPh...15....3S
Altcode:
  The mean photospheric magnetic field of the sun seen as a star has
  been compared with the interplanetary magnetic field observed with
  spacecraft near the earth. Each change in polarity of the mean solar
  field is followed about 4 1/2 days later by a change in polarity
  of the interplanetary field (sector boundary). The scaling of the
  field magnitude from sun to near earth is within a factor of two of
  the theoretical value, indicating that large areas on the sun have
  the same predominant polarity as that of the interplanetary sector
  pattern. An independent determination of the zero level of the solar
  magnetograph has yielded a value of 0.1±0.05 G. An effect attributed
  to a delay of approximately one solar rotation between the appearance
  of a new photospheric magnetic feature and the resulting change in
  the interplanetary field is observed.

Title: The Weak Magnetic Fields of Some Bright Stars
Authors: Severny, A.
Bibcode: 1970ApJ...159L..73S
Altcode:
  The technique of the solar magnetograph applied at the coud

  Astrophysical Observatory for the measurement of stellar magnetic
  fields has recently revealed weak longitudinal magnetic fields ( gauss)
  of some bright stars.

Title: On the Asymmetry of Moustaches
Authors: Koval, A. N.; Severny, A. B.
Bibcode: 1970SoPh...11..276K
Altcode:
  A careful photometry of moustaches is carried out to reveal asymmetry
  of their emission in the far wings (Δλ ⩾ 1 Å), if it exists. The
  presence of background continuous emission in spectra of moustaches
  demands special care with the photometry, and makes the current method
  of comparison of rest-intensities inadequate. The other sources
  of errors are also discussed. The blue asymmetry, as a systematic
  difference of intensities between the blue and the red wing shows itself
  in some cases, being 2-3 times larger than the probable errors. In
  most moustaches investigated, the accompanying background continuous
  emission shows a rapid increase to the violet.

Title: Is the Sun a Magnetic Rotator?
Authors: Severny, A.
Bibcode: 1969Natur.224...53S
Altcode:
  MEASUREMENTS of the general (polar) magnetic field of the
  Sun<SUP>1</SUP> show that since September 1964 the Sun has behaved
  on average like a dipole with a negative field strength at the North
  Pole and an approximately equal positive field at the South Pole (the
  mean ranging from 0.5 to 1.0 G). But because of a bias toward the area
  of the negative polarity in the northern hemisphere, the net magnetic
  flux was on average negative most of the time; in this sense the Sun
  behaved like a ``monopole''. There were large deviations from the mean,
  however; for example, sometimes both poles had a field of the same sign
  (in February-April 1965), and during the first half of 1964 the mean
  strength at the South Pole was zero.

  Photoelectric measurements of both the longitudinal and transverse
  components of magnetic fields were made daily during 17-24
  September, using the line Fe I A5250; the resultant magnetograms
  refer to fields &lt;1000 G. The aperture corresponded to 2" X 4";
  image motion may occasionally enlarge this resolution to about 6"
  x 8". Careful registration of the magnetograms, photoheliograms,
  and HCL filtergrams ensures accuracy of flare positions to within the
  resolution of the magnetograms. Emphasis is placed on the position of
  the emission knots that represent the first brightening of a flare:
  (1) For 27 flares, 70% had first brightenings limited to two or three
  points or knots, that occur nearly simultaneously in widely separated
  parts of the activity center. The initial knots are separated by the
  magnetic neutral line that divides regions of opposite polarity. Only
  two flares had all their initial knots in a region of one polarity. (2)
  At least one of the initial knots of a flare tends to lie humediately
  adjacent to the neutral line, and in a region of greatest longitudinal
  field gradient. For 60 separate knots, 80% were situated such that the
  distance from the center of the knot to the neutral line was less than
  10". (For comparison, the distance between the three umbra composing the
  region was about 60"). Only four flares had an initial knot overlapping
  the neutral line. (3) From 17-21 Septen~~er the flaring tends to favor
  two distinct centers in the region. One center corresponds approximately
  to where the transverse field vectors appear to cross or l~erge. The
  resulting bifurcated appearance is suggestive of crossed transverse
  fields. Other flares tend to occur in regions of strong, oppositely
  directed, electric currents.

Title: Solar Magnetic Fields
Authors: Severny, A.
Bibcode: 1964SSRv....3..451S
Altcode:
  This paper is a review of our observational knowledge on solar magnetic
  fields. In Section 1 we make an attempt to summarize all observations
  of the general magnetic field (m.f.) of the Sun. Section 2 deals with
  the local m.f. at low latitudes and their connection with some features
  on the disk. The m.f. of sunspots and their peculiar character are
  considered in Section 3. The last section (4) is concerned with m.f. in
  sunspot groups, their changes and connections with solar activity.

Title: Solar Magnetic Fields and the Great Flare of July 16, 1959.
Authors: Howard, Robert; Severny, A.
Bibcode: 1963ApJ...137.1242H
Altcode:
  Ten magnetic maps of the active region on several days at the time of
  the 3+ flare of July 16, 1 were obtained at the Crimean Astrophysical
  Observatory. At some time during a 15-hour interval wil which the
  flare occurred, the higher magnetic fields near and inside the sunspots
  decreased by near factor of 3. The resulting loss of magnetic energy
  amounted to about 1032 ergs, which is the estim energy emitted in the
  form of cosmic rays from flares. Magnetic observations made of the
  active re at Mount Wilson during the course of the flare could not have
  shown the changes in the stronger fi seen in the Crimean observations.
