Comet Hartley 2 and the Sun.

I have been asked by a friend, and member of my local astronomical society, Macc Astro Soc.
If I can post a couple of observing reports, together with a picture, taken recently of C2003P Hartley 2 and a drawing of the Sun. Drawn using a Coronado PST, by Mr Paul Canon.


Sun Sketching

The Sun was very active  on Wednesday. There were four  sunspot regions in the disc. Each region was surrounded by a large plage. Two large broad filaments were in the north east quarter with a smattering of smaller ones scattered around the disc. South east there was a plage region with a large filaprom visible. Around the limb there were groups of prominences, but not on the south west limb that I could see. The largest prominences were along the south east limb. Two unusual ones were near the north pole, one hanging above the limb the other looking like a tree trunk with a single branch.








Comet 103P Hartley 2

A go at Hartley through the murk  early Tuesday morning. 5 x 5min images stacked on the head and   processed in  Photoshop. The comets tail in this image is towards the north east off the central core. The  coma around the core is very large, but diffuse and requires processing to bring it out.
