S; Sharma, P; Devgun, C. B<br/><br/>Abstract: Twenty pictures of solar corona were taken on October 24, 1995 from Bhind on the central line of totality, covering a wide range of exposure times a 500mm telephoto lens captured Images on 35mm film duly calibrated. This sequence has provided valuable intensity data during the solar minimum. These frames have been digitized, giving lsophotes beyond 1.5 solar radii.

D; Kulkarni, A. G<br/><br/>Abstract: Systematically planned observations conclusively reveal that sudden and large natural changes in the ambient light conditions during a total solar eclipse for a few minutes, initiates and cause marked alterations in the normal behavior pattern of the primates. Observations on the individual as well the group dynamical behavior among the red-faced Bonnet monkeys and the black faced Hanuman Langurs in the thick forested area near Ankola in Uttara Kannada district of Karnataka during the total solar eclipse are reported here.

N; Ghosh, V; Krishna, J. B. M; Verman, J. R; Prakash, H; Pal, G; Mishra, N. R; Bera, M; Reddy, V. R; Ranganath, M. R; Majumdar, C. K<br/><br/>Abstract: The γ-ray and X-ray background was measured at Diamond Harbor located on the total eclipse phase path, during total solar eclipse (TSE) which occurred on October 24, 1995. The data taken by two high resolution γ-ray detectors, a γ discriminator system comprising a liquid scintillator system and a high resolution Si(Li) x-ray detector when analyzed show a sharp dip in both γ-ray and X-ray integral counts over the energy range 150 KeV to 1300 KeV and 1 - 80 Kev respectively coinciding with the TSE time. Also the integral background spectrum vs. eclipse time indicates from the sharp peaking in the background reduction coinciding with exact total eclipse time, that most of this 9% to 10% reduction in both γ and X rays is from the central portion of the Sun. This also agrees with the optical phases of the Sun. The preliminary analysis and inferences of the data are presented in this paper. Further analysis of the data is in progress.

S<br/><br/>Abstract: Flash spectra were recorded at video rate from Behind, Madhya Pradesh A holographic transmission grating, was used in front of a CCD video camera. Using a. solar Image of 0 5mm diameter, the spectrum on the CCD was recorded on 8mm video format at both 2nd and 3rd contacts. The Hα line is visible around 2nd and 3rd contacts for 24 and 18 seconds respectively Prominent emission lines visible are Hα, He, II, Hβ. H. Ca H & K lines for analyzing the growth and decay of emission lines the entire video data have been digitized; consisting of 170 megabytes. An interesting feature observed on digitizing is the fluctuation in the intensity of the CN lines (3883Å). Tue, 29 Oct 1996 22:58:59 GMT
