[BAA Comets] Fw: Animation of 2013US10 tail features from this morning 21st Dec

[Shanklin, Jonathan D.]

If I've done the sums correctly its about 200 km/sec, though I have made several approximations.

Regards,

Jonathan Shanklin

Hi all,

I was plagued with broken cloud this morning but did manage some images of C/2013US10.  As the 120 second exposures appeared on my observatory PC monitor it was obvious  there was activity in the gas tail.

I’ve put together this 4 frame animation showing features moving down the tail. The four frames span 6 minutes between 06.05UT and 06.11UT.

The coma is just off the image and the frame is 36 arc mins wide.

It sure must be “windy” up there!!

Peter
