ALEXIS has detected a transient in Telescope 2B (183 Angstroms, 66eV) at:

         RA=251.23 Degrees (16 44 55)
         DEC=-3.21 Degrees (-03 12.5m)
         (Current Epoch)

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

There was no evidence of the object in the co-aligned telescope 2A (130
Angstroms, 93 eV). The outburst appeared to start early on 4 May, 1995 UT.
In the latest data, this source is still visible. It initially
appeared about as bright in Telescope 2B as HZ43, which was being observed
simultaneously and has remained at that level in all of the 5 May, 1995
data. At the count HZ43 count rate, this source is about 0.15
photons/cm^2/s/A.
It is currently near the edge of the FOV making precise flux and position
measurements difficult. Simbad only show 15 sources within the error box
with no good candidates for optical counterparts. Observations made at this
time will aid in the identification of the optical counterpart.
