Comet 217P/Linear

Excited comet watchers have been following with interest the prospects of Comet 217/P - Linear.

Comet hunters have been following it since David Cardenosa from Bootes Observatory in Spain (J05) reported some outbursts on the 22nd.

My Obs from this morning from D90, whilst I was tucked up nicely in bed asleep.....ah the joys of remote astronomy.

217P C2009 08 26.75348 03 49 59.73 -03 11 43.7 14.05R D90
217P C2009 08 26.75433 03 49 59.90 -03 11 45.5 13.78R D90
217P C2009 08 26.75519 03 50 00.16 -03 11 46.0 13.21R D90
217P C2009 08 26.75603 03 50 00.30 -03 11 46.0 13.70R D90

The comet looked a treat at about Mag 10.8 based on nearby catalog stars. It certainly makes a pretty picture passing those two deep sky galaxies.

As you can see its still holding together reasonably well, although does still have a slightly "out of shape" coma.

From the very useful online application Photometrica you can see the 3D shape of the coma.

Closer inspection shows a similar profile to what our Spanish friends observed.

I am still to download all the files, so maybe more later.

Musically reflecting on this, 217P is proving the time honored truth....."breaking up is hard to do."

UPDATE: I have downloaded the rest of the photos and done a 20 x 20 Sec stack.
