IPN Triangulation of GRB 010412
Hurley et al.
SOURCE: GCN
TITLE: GCN GRB OBSERVATION REPORT
NUMBER: 1036
SUBJECT: IPN Triangulation of GRB 010412
DATE: 01/04/13 16:54:08 GMT
FROM: Kevin Hurley at UCBerkeley/SSL <khurley@sunspot.ssl.berkeley.edu>

K. Hurley, on behalf of the Ulysses GRB team, and C. Guidorzi, E. Montanari, and F. Frontera, on behalf of the BeppoSAX GRBM team, report:

Ulysses and BeppoSAX GRBM observed this burst (GCN 1035). As observed by Ulysses, it had a duration ~80 s, a 25-100 keV fluence of 9.4x10^-6 erg/cm^2, and a peak flux over 0.5 s of ~9 x 10^-7 erg/cm^2 s. These numbers are subject to more than the usual uncertainties because Ulysses is recording a solar proton event which raises its background by a factor of 2 or so. Triangulation gives an annulus centered at RA 3.671, DEC -21.012 deg., with radius 75.856 +/- 0.034 deg. (3 sigma). This intersects the WFC error circle to form an error box whose area is approximately 47 sq. arcmin. and whose corners are at

RA(2000) DEC(2000)

This error box can be refined by further processing.
