 Total Solar Eclipse captured at Vanarpati and Masulipatam on August 18, 1868 | Result: 1. First-time spectroscopy applied to a solar eclipse. 2. Detection of Hydrogen lines in emission in chromospheres. 3. Observation of the yellow line near the sodium D line later attributed to Helium. |
 Total Solar Eclipse captured at Sahdol on January 22, 1898 | Result: White light photo-graphs of different scales were obtained. |
 Total Solar Eclipse captured at Miahuatlan, Mexico on March 7, 1970 | Result: Detection of cooler gas in hot million degrees corona inferred from hydrogen, helium coronal region. |
 Total Solar Eclipse captured at Jawalgera and Hosur on February 16, 1980 | Result: The high-resolution multi-slit spectra showed that solar corona is remarkably quiet and it corotates with photospheric layers. Detailed information on temperature motions and the structure of solar corona was obtained. It was found that collisional excitation dominates up to 1.3 solar radii, and beyond 1.3 R, radiative excitation dominates. |
 Total Solar Eclipse captured at Tanjung Kodok, Indonesia at June 11, 1983 | Result: These experiments confirmed the findings of 1970 and 1980 eclipses findings. |
 Total Solar Eclipse captured at Neem Ka Thana, Rajasthan, India, on October 24, 1995 | Result: 1. The dust ring around the sun was not found as predicted by some earlier observations. 2. Detection of Short-Period Coronal Oscillations |
 Total Solar Eclipse captured at Maitri, Antarctica on November 23, 2003 | Result: Spica and Jupiter are recorded in some frames. The diamond rings were recorded for four seconds before the second contact and for an unusually long duration of close to 30 seconds after the third contact. Shadow bands on a 1m square board (seen with the frames) were recorded at a site near Maitri in Antarctica. |
 Total Solar Eclipse captured at Manavgat, Turkey, on March 29, 2006 | Result: Intensity Oscillation in the Corona as Observed during the Total Solar Eclipse of March 29, 2006. |
 Total Solar Eclipse captured at Easter Island, Chile, on July 11, 2010 | Result: Successful observations made. Data is being analyzed to understand the chromospheric. |
