Check my feed daily this week and next for a “comet tracker” with sky-charts and tips for viewing Comet A3 (Tsuchinshan-ATLAS). Comet A3 is expected to brighten dramatically, visible in the east before sunrise and in the west after sunset. It may become a naked-eye target, especially with good planning and clear weather. On Friday, Sept. 27, look east-southeast an hour before sunrise (around 07:00 in the U.S.) to see it at its brightest, with an expected magnitude of +4.5.
