ALEXIS has detected an EUV transient in its 1B telescope (172 Angstroms,
71 eV). There is no detection of the source in the co-aligned 1A
telescope (130 Angstroms, 93 eV).
Position: RA,DEC = 13 59 27.6, +53 54 40.3 (J2000 Coordinates)
90% Error Circle Radius = 0.5 degrees
Due to an operational problem, there is no ALEXIS data for 12 hours prior to
23H UT Feb 9. The source was already bright at 0H UT Feb 10, and continued to
be active through 06:30H UT Feb 10. The next data dump from ALEXIS will occur
around 20UT Feb 10. I will post more information after that time as it
becomes available.
Groundbased observations made at this time will aid in the identification
of the optical counterpart.
