New possible ALEXIS transient on Jan. 18

New possible ALEXIS transient

(vsnet-alert 314, 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
