#Comet #12P #PonsBrooks below Jupiter sinking into the murk on April 11. Probably my last opportunity for this one
Turn your eyes to the sky for a two-for-one astronomical spectacle as the 'devil comet' finally creeps into view for the southern hemisphere just in time for the Lyrid meteor shower! ☄️
The Comet Pons–Brooks is visible to the naked eye, but only if you know where to look.

The green color seen in the coma of most comets, but not in their tails, is due to emissions from Diatomic carbon C2 (aka dicarbon) molecules.
Sunlight heats the comet’s ice and organic material to produce C2 molecules, which break apart in ~2 days before they reach the tail. C2 is excited by solar UV radiation and emits mostly in infrared but its triplet state radiates at 518 nm (d3Πg → a3Πu transition below).

#Comet #12P #PonsBrooks (very faintly visible, upper left) over the #Moon last night. This is a somewhat fake composite of 100 4 second frames, aligned separately on the stars, moon and foreground. Too close to twilight to get much of the comet
Too bad: The clouds were eventually gone, but when it finally got dark enough to make out #Comet12p #PonsBrooks on the photos of my amateur camera, it disappeared behind the trees. So, no chance of getting a shot of its tail. 🙁
Still: A nice constellation of the crescent Moon, Jupiter (with three of its own moons), and Uranus. 🙂
