Comet 220P/McNaught
Tuesday, August 11, 2026
August 10, and another comet. This is 220P/McNaught, a periodic comet which recently exploded and brightened enormously (see Aug 9 entry), from magnitude 17 up to 7 or so:
It’s quite distant so isn’t as good a target as C2025R3 back in April. But it’s higher in the sky.
