[vsnet-alert 314] possible ALEXIS transient

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

ALEXIS has detected a transient in Telescope 3A (170 Angstroms, 72eV) at:

         RA= (07 14 16.21)
         DEC=(+10 43 56.3)
         (Current Epoch)

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

Another known source in the same detector scan path (G191-b2b) is detected
within 16' of its known position. There was no evidence of the object in
the co-aligned telescope 3B (66 eV). We are attempting to get EUVE to slew
around as I write to look at this as a TOO. The source turn on appeared to
start about 12 UT 18 Jan and was still bright at the end of the last data
set which we got a few hours ago and looks like it had been bright for >24
hours. A flaring episode occurred about 0UT 19 Jan.

Simbad only show 12 sources in this direction, l=206, b=+10, which are F, K
and A stars with a few iras sources thrown in.

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

More information will be included in the next message
