Any residual visual light from this supernova that occured last night - the most distant naked eye visual object ever seen from Earth - will probably be washed out by the full Moon, but here's a finder chart anyway. May be worth throwing a quick binocular on it: My amateur finder chart at: http://gallery.utahastronomy.com/main.php?g2_itemId=11063 Decimal position data from Swift Uvot image files at: http://swift.gsfc.nasa.gov/cgi-bin/sdc/list?seq=sw00306757000.013 converted to ra-dec: Right-ascension 217.917 143139.99 Declination 36.304 +361813.1 Approx. 2 degs due south dec of gam Boo. NASA Press releases http://www.nasa.gov/home/hqnews/2008/mar/HQ_08086_Swift_Detects_GRB.html http://www.nasa.gov/mission_pages/swift/bursts/brightest_grb.html ====== "This burst was a whopper," said Swift principal investigator Neil Gehrels of NASA's Goddard Space Flight Center in Greenbelt, Md. "It blows away every gamma ray burst we've seen so far." Swift's Burst Alert Telescope picked up the burst at 2:12 a.m. EDT, March 19, and pinpointed the coordinates in the constellation Boötes. Telescopes in space and on the ground quickly moved to observe the afterglow. The burst is named GRB 080319B, because it was the second gamma ray burst detected that day. Swift's other two instruments, the X-ray Telescope and the Ultraviolet/Optical Telescope, also observed brilliant afterglows. Several ground-based telescopes saw the afterglow brighten to visual magnitudes between 5 and 6 in the logarithmic magnitude scale used by astronomers. The brighter an object is, the lower its magnitude number. From a dark location in the countryside, people with normal vision can see stars slightly fainter than magnitude 6. That means the afterglow would have been dim, but visible to the naked eye. . . . . GRB 080319B's optical afterglow was 2.5 million times more luminous than the most luminous supernova ever recorded, making it the most intrinsically bright object ever observed by humans in the universe. The most distant previous object that could have been seen by the naked eye is the nearby galaxy M33, a relatively short 2.9 million light-years from Earth." ======= Blogged reports from around the world by professional observatories http://grad40.as.utexas.edu/grblog.php?view=burst&GRB=20080319B Swift site xray and visual camera images http://swift.gsfc.nasa.gov/docs/swift/swiftsc.html - Kurt ____________________________________________________________________________________ Looking for last minute shopping deals?

Kurt, you left out the most astounding bit from the news release; the estimated distance of the GRB. Yikes! "Later that evening, the Very Large Telescope in Chile and the Hobby- Eberly Telescope in Texas measured the burst's redshift at 0.94. A redshift is a measure of the distance to an object. A redshift of 0.94 translates into a distance of 7.5 billion light years, meaning the explosion took place 7.5 billion years ago, a time when the universe was less than half its current age and Earth had yet to form. This is more than halfway across the visible universe. "No other known object or type of explosion could be seen by the naked eye at such an immense distance," said Swift science team member Stephen Holland of Goddard. "If someone just happened to be looking at the right place at the right time, they saw the most distant object ever seen by human eyes without optical aid."
