C/2020 S3 (Erasmus) @ 2020 October 29, 11:49 UT

Comet C/2020 S3 Erasmus imaged on October 29, 2020 just before the Moon entered into the morning sky. Since my previous image two weeks ago, it has increased in brightness from magnitude 11 to 10, with a coma that has increased in angular size from 3 to 5.5 minutes and a tail that begins to be noted toward west (to the right). Angularly approaching to Sun, in November we will have the last chance to observe it already within reach of binoculars.
