Narrow Band Photometry in Emission Lines during the Total Solar Eclipse of October 24, 1995

Abstract

To investigate the spatial variation of tempereture and density within coronal strucures, narrow band photometry in three coronal emission lines was done during this eclipse. The emission lines 6374 (FeX), 7892 (Fe XI) and 5303 Armstrong (Fe XIV) represented temperatures in the Armstrong range of 1-2 million degrees. Peltier cooled CCD camera was used to record the coronal images thorugh 5 Armstrong interference filters with pixel resolution of 11 arcsec.
