Comet C/2012 S1 ISON in STEREO H1 A Beacon Images (20-22 November, 2013)

Comet C/2012 S1 ISON as seen in the low resolution beacon images from the H1A instrument form 20-22 November. Nice and bright with a good tail. The tow bright objects are Mercury and Earth, respectively.Animated GIF of the 10 frames of ISON entering the H1A imager. Click to embiggen. Looks like there is some significant tail activity.

Comet C/2012 S1 ISON continues to pass through the field of view of the STEREO H1A instrument. Even in the low resolution images at the momen it is looking good, much brighter than 2P/Enke was.It should be great when we get the high resolution images in a couple of days.
