Re: Unusual brightening of comet C/2023 Q1
¿ªÔÆÌåÓýMy entry for the comet for The Astronomer magazine covering observations to the end of November and giving the behaviour for November was: 2023 Q1 (PANSTARRS) observations cover: -144 to -16 days, 2.6 ¨C 3.0 au At 17.5, steady (Carson, Pappa) ? Which does suggest that the brightness seen in December is unexpected. ? I won¡¯t start putting the TA column for the next issue together until around January 4. ? ? Regards, ?

? Hello Thomas, Here are my observations from summer?to now. Unfortunately, I made no observations in October and early November, so although the comet has brightened,?it is not clear if the brightening occurred over a short or long period. ?
