LANL's ALEXIS satellite, containing six wide field of view EUV telescopes was launched April 25, 1993. ALEXIS is a sky monitor/survey experiment, and with each 50 second rotation, the satellite's six telescopes scan nearly half of the sky. Due to the damage sustained at launch by the satellite, the ALEXIS project team has had to spend over a year devising new methods to determine spacecraft attitude knowledge, essential for putting photons back on the sky correctly. These efforts have been successful and currently the ALEXIS attitude solutions are precise to better than 0.5 degrees which is the minimum requirement to be able to detect weak sources in the skymaps. The first ALEXIS skymaps were produced on November 4, 1994 which revealed several point sources in addition to the previously detected HZ43 and the Moon using less sophisticated processing. In addition, starting in 1995, daily sky maps are searched for point sources in an effort to detect EUV transients with a 12 to 24 hour response time. This paper will discuss the number and types of transient point sources that have been revealed in the ALEXIS data to date, in particular 1) the June, 1994 superoutburst of the Cataclysmic Variable VW Hyi, 2) the Nov-Dec, 1994 outburst of ALEXIS J1114+43 (=1ES 1113+432) and 3) the fast transient ALEXIS J1139-685.
