Title: Fine structure of the solar chromosphere
Authors: Bhavilai, R.
1975STIN...7525808B    Altcode:
  The sun was observed in the H-alpha line and around it in the quiet
  regions and in the active regions. Preliminary results were obtained
  concerning the life-times and changes of the fine structures in the
  quiet regions and the active regions, the bright streaks and the
  identification of the H-alpha plages and the photospheris faculae.

Title: The Bright Streaks in the H&alpha Disk Chromosphere
Authors: Bhavilai, Rawi
1968SoPh....5..471B    Altcode:
  Evidence is presented demonstrating the existence of a type of
  chromospheric structure in the form of bright streaks. These are
  extensions across the solar disk of elongated bright mottles which
  originate in the central regions of clusters of mottles. They are best
  observed on good filtergrams at Hα ± 0.5 Å through comparison with
  filtergrams at other positions on the line profile. Their length can be
  as much as 200 sec of arc. The bright streaks appear to be predominantly
  horizontal loop structures, while the well-known spicules are mainly
  vertical structures. A bright streak may be well defined or rather
  diffuse along its length, and many of them are accompanied by darker
  boundaries or envelopes. It is usual to find a loop of bright streak
  bridging the central areas of two mottle clusters. It seems that the
  observed pattern in the space between the chromospheric network at Hα
  ± 0.5 Å results partly from the interactions of the bright streaks
  of different stages of evolution traversing the area in different
  directions.

Title: The structure of the solar chromosphere, I: Identification
    of spicules on the disk
Authors: Bhavilai, Rawi
1965MNRAS.130..411B    Altcode:
  Spicules have been studied in the H line with (a) a i/8 A tunable
  filter, and (b) a 3/4 A filter equipped with a beam splitter yielding
  simultaneous photographs in opposite wings. Spicules have been traced
  from outside the solar limb on to the chromospheric disk just inside
  the limb, where they appear as bright emission featares. On the disk,
  they appear as mottles which are bright at all positions across
  the line profile. The well-known dark mottles, although merging to
  form the general chromosphere at the limb, do not extend beyond as
  spicules. However, there is a close association between the dark
  and bright mottles, the latter being found in the central parts of
  the well-known chains of the chromospheric network or of clusters of
  dark mottles. A three-dimensional model of some of these structures
  is described.

Title: The "double Limb" in Ha.
Authors: Bhavilai, Rawi; Norton, D. G.; Giovanelli, R. G.
1965ApJ...141..274B    Altcode:
  Photographs of the solar chromosphere in monochromatic light of
  pass band 1s A centered on Ha show that the well-known "double limb"
  vanishes on eliminating all traces of the surrounding continuum. The
  inner limb is spurious and is simply an image of the photosphere in
  stray light of unwanted wavelengths.
