>Possible naked-eye gamma ray burst detected (GRB 080319B)
>March 19, 2008
>
>The intense gamma-ray burst GRB 080319B was detected in gamma ray, x-ray,
>optical light, and early indications by two automated cameras suggest that
>the optical afterglow of the burst may have briefly reached naked-eye
>visibility (mag ~ 5.76, GCN 7445, Cwiok et al) within 60 seconds of the
>onset. It is highly unlikely the burst was caught visually, but it is
>possible the burst may have been detected if any observers were monitoring
>this area of the sky (e.g. for minor planet searching).
>
>The coordinates of the burst are:
>
>RA: 14 31 40.98 , Dec: +36 18 8.8 (J2000)
>
>Observers with any images of this field taken since 2008 March 19 0600 UT
>are urgently asked to check these images for optical transients. This
>includes wide-field images, sky and meteor patrol images, and any and
>all CCD imaging, filtered or not.
>
>Observers are also asked to obtain additional images of this field as
>the afterglow decays. The object was at magnitude 16 less than ten
>hours post burst, but it may remain within range of observers with
>12-inch or larger telescope apertures and CCD cameras.
>
>If you are able to obtain any magnitudes, magnitude estimates, or limits
>from your images, please submit them to the AAVSO with the name
>"GRB 080319B" or AUID "000-BFT-137".
