Sequence now available for V6566 Sgr

A sequence is now available for V6566 Sgr (N Sgr 2020). The field is extremely crowded, and it is recommended to create an 'f' or 'g' scale chart (18.5 arcmin and 7.5 arcmin, respectively). Many thanks to AAVSO Sequence Team member Tom Bretl!

Good observing,

Elizabeth
