Annular solar eclipse of June 21

Because of COVID-19 lockdowns unable to travel into the zone of annularity, where a 0.3% annulus of everyday sun remained around the lunar silhouette at maximum, Prof. Pasachoff monitored the eclipse progress from Williamstown on the Web.  He had made suggestions to several observers in Oman and India for observing methods and, together with Prof. Marcos Peñaloza-Murillo, arranged for temperature measurements to be made—with one report from Oman showing the temperature declining from 116°F as the eclipse began own to 90°F just after annularity (a drop from 45°C to 32°C).
