Comet 252P/LINEAR

#1 Post by rwilkinson » Wed Mar 30, 2016 11:19 am

This is the comet which whizzed past the Earth at mere 3.3 million miles last week, and was seen by many in the Southern hemisphere.

Now we have a chance to see it for ourselves as a morning object in Ophiuchus, but it's fading down below 6th magnitude.
Tomorrow morning it will be quite near to the last quarter Moon, but Saturn and Mars will also be lined up to the South as a reward for early risers:

It was cloudy in Bolton this morning (raining, in fact!), but I still managed to get an image of this comet - from the iTelescope T3 in New Mexico:

As well as having better weather, their sunrise is seven hour later than ours, so I took these images just before lunchtime.

This is the comet which approached to within 3.3 million miles of Earth back in March.
I'd taken images of it using the iTelescopes in New South Wales and New Mexico, but last night I finally got an opportunity to image it from Bolton.
It's recently been reported at around 8th magnitude (integrated), but it is now very diffuse, and so difficult to pick out in the moon-glow (and twilight, at this time of year). Nonethelesss, I aimed my 'scope at some nearby stars and took a set of images either side of midnight.
Then this morning's processing confirmed that I had definitely captured this comet:
