Update on Comet PanSTARRS in STEREO

Image credit NASA/STEREO

Comet C/2011 L4 PanSTARRS captured in the low resolution beacon images for the STEREO Behind  H1 imager.

Still waiting to download the high resolution images, but this expanded set of beacon images you can distinguish between the image artefact spike and the dust tail (the spike is the straightish line, the broad fan of the dust tail sweeps off to the right, compare to yesterdays set).

Also in the image is Mercury (up close to the Sun) and Earth (the bright dot centre right).

Here's another animated GIF.  There is a better one at the STEREO site.

The hi-res images have been published and widely discussed on Monday already: http://skyweek.wordpress.com/2013/03/09/allgemeines-live-blog-ab-dem-9-marz-2013
No, only a processed image has been released, we are still waiting for the HiRes images to become available in the STEREO archives (juts checked again, only the 9th is there).

Karl may have access to them, but not me :-)
