CommentsMars should have been a nice sight in the binodular just to the upper left of M44, but I couldn’t see the cluster. Asellus Australis (Mag 3.94) was easily seen but there was only a hint of something over at Asellus Borealis (Mag 4.66).

CommentsI had hoped to locate the three main stars of the constellation by using Regulus and 31 Leo (Mag 4.39) as pointers but I couldn’t find 31 Leo so the Mag 4.5 – 5 stars of Sex were out of the question

Just before the flare was due to occur the street lamp out in that direction went out and I could finally see Denebola (Mag 2.14) and Algieba (Mag 2.01) naked-eye.

Out to the west it appeared darker. I identified Cygnus and Lyra. Overhead I wasn’t able to see alcor.
