ALEXIS has detected a possible transient with a likely potential counterpart.
The source was detected in our 170 angstrom channel (telescope 1B).
The negative caveats here are that the source is near the edge of a
telescope scan path and the total amount of exposure is small.
The positive caveats are that the source has a high statistical
significance, and it is very nearly coincident with a Rosat WFC source
that was not detected in the EUVE Second catalog, potentially indicating
variability.
The transient is located at ( RA = 11 04 2.46 DEC = -04 02 41.0) +/- 0.5
degrees, current Epoch.
The source was detected in the last 48 hours of data, and is consistent
with the Rosat WFC source: 2RE J1104-041.
Here are the details on that source:
