30 years ago #OTD I was in #India to observe a Total #SolarEclipse lasting under a minute in Neem Ka Thana, Rajasthan: my report on the whole trip to this amazing country - written originally for an English magazine - can be found at https://geocities.restorativland.org/CapeCanaveral/5599/india_95_story.html while the picture here was taken by Voyto Rušin at the same observing camp and processed by Miloslav Druckmüller: http://www.zam.fme.vutbr.cz/~druck/eclipse/Ecl1995i/0-info.htm
