(Please pardon me if this has been referenced before.) The Alexis satellite's home page is: http://alexis-www.lanl.gov/ For telescopic observers, the following page, containing information about the satellite, says that it spins once every 50 seconds: http://alexis-www.lanl.gov/~asocops/education_outreach.html#anchor64763 Okay, the (flash?) period is known. Has anyone observed this tiny thing flashing? (Mike, please pardon me if I've seen it flashing in your telescope and forgotten....) These Alexis pages include the satellite's current location (Java and no-Java), pass times over Los Alamos, and a lot of other information, but no TLEs. Ed C.
