AR-2020-21

129 33 rd ANNUAL REPORT 2020-21 In order to keep general public occupied with sky related activities during the lockdown, we presented them a "Moon Challenge", in which they have to look at the Moon at least once every day, over one complete lunar cycle of phases, i.e., from one new moon to the next. The SciPOP team also did this at the same time. StartingApril 23, 2020, many people joined in this, and strived to be with us through the whole lunar cycle. The event was conducted by Samir Dhurde (IUCAA) with the help ofAtharva Pathak, and was actively helped with regular telescopic pictures of the Moon by amateur astronomers Revati Dokhe, AnirudhThakar, and PrabhakaranKutti.
