Comet C/2021 A1 Leonard

7 Dec 2021: This moderately bright comet is now a nice object in binoculars from a reasonably dark sky. A small telescope is better from suburban areas. I made it 7th mag last night from a suburban sky.

However, it is rapidly moving south and by 12 December it is only 5.3° high at the start of Nautical Twilight (Dublin; at 05.57 UT). On the morning of 9th December it lies 9° above (or NNE) 2.6 mag star Alpha Serpentis. So catch it while you can.
