[vsnet-alert 300] possible ALEXIS transient

[droussel-dupre@lanl.gov (Diane Roussel-Dupre)]

ALEXIS has detected a transient in Telescope 1B (170 Angstroms, 72eV) at:

         RA= (23 54 36.53)         [23 54 48.24]
         DEC=(-37 49 13.4)         [-37 39 25.2]
         (Current Epoch)           [Epoch 2000]

         Error circle radius = 0.5 degrees (~90% confidence)

There was no evidence of the object in the co-aligned telescope 1A (130
Angstroms, 93 eV). The outburst appeared to to be in 2 flaring episodes,
one at 10 UT 26 Dec, 1995, and the other starting at 4 UT 27 Dec, 1995 and
continuing to 7 UT 27 Dec, 1995 when the data was downloaded from the
satellite.The second flaring episode was much brighter than the first. The
next data down from the satellite will be at 15:14 UT 27 Dec with point
source information available about 2 hours later.

Simbad only show 13 sources within the error box with no good candidates
for optical counterparts.

Groundbased observations made at this time will aid in the identification
of the optical counterpart.
