1. The closest the comet will come to Earth is 0.23 AU (Astronomical Units), or approximately 34-million kilometers, so it poses no threat to us. We will attempt to keep this page updated with the latest observations.http://stereo.gsfc.nasa.gov/gallery/item.php?id=selects&iid=154
Try, for example, "Ahead HI1," "Slideshow," 512 x 512 resolution, start date = 20110801, and end date = 20110803.
I've labelled objects I recognize on the attached image. I believe the object to the lower right of Alpha Sco is M4.
You can also get an approximate idea of what's in the field of view (which is larger than the circle in he resulting diagram) with the SECCHI star map tool at:http://secchi.nrl.navy.mil/index.php?p=sky/secchimap
(enter date, spacecraft, instrument at the bottom of the page). The dashed, red line is the ecliptic.
