Comet Neowise July 21st 2020

Comet Neowise was easily visible with the naked eye during these days. The broad yellowish tail is the dust tail, and the smaller blue one is the ion tail mostly from CO+. After closest approach to the sun the coma turned green which is an indication of high amount of CN and C2 molecules.
