C/2020 F3 (NEOWISE) – a memorable moment
Around 17th July, the core of the Neowise comet starting giving a greenish-glow. At first, I thought this is due to some glitch in my camera sensor (I used an entry-level DSLR), but other photos online also started reporting this greenish glow. It has been speculated to be because of the formation of a new vent on its surface discharging gaseous ions which starting glowing green in the presence of sunlight.
