[BAA Comets] C/2013 US10 (Catalina) this morning

[Nick James]

Jonathan,

I got mag 6.5 using my VEM software which is nicely consistent with your 
estimate:

Yes, it's not as bright as it could have been but it is still a very 
nice comet. The tail length on my image from this morning is around 2 deg.

I'm still optimising my software but I hope soon to start feeding 
properly formatted magnitude estimates into COBS.

Nick.

> The comet was conveniently placed from my bedroom window in central Cambridge, so I didn't even have to go outside.  Mag 6.3 in 20x80B, with a short tail, and similar mag in 8x40B, but no tail.  Nice, but I think that Venus, Mars, Jupiter and the Moon would probably attract more public attention.  Unless the comet does something unexpected it won't be as widely observed as seemed possible six months ago.
