C/2021 A1 (Leonard) 2022-Jan-07 Mike Olason
Twilight and lower comet altitudes continue to merge here in Tucson as one can see from the color image at 0130UT. Comet C/2021 A1 is about the same magnitude this evening as the past 2 evenings. Astrometrica calculated V=6.4 on 10x20s green filter images, R=6.3 on 4x20s red filter images and V=6.3 on 5x20s unfiltered images at 0133, 0137, 0139UT. Forecast is for increasing clouds and showers the next week, so you all may be spared from anymore of these sad looking images.
