Observation Notes
This was a fantastic sight! The comet shared the view with brilliant, second magnitude Alpha Coronae Borealis. The nucleus still appeared stellar with a fan shaped tail blowing to the southwest. The tail seemed to trail about 38', distending an angle of about 45°. The brightest portion was still the northwest edge. Motion was apparent over the course of the observation, but I didn't end up marking it.
I was able to find both the B and C components with my 10 x 50 binoculars (hand held). They both just barely fit in the field together.
