    It is not because of geo sat flare season - this applies to active,
    stabilized geostationaries that have their solar panel normals pointing near
    the Sun, but in the equatorial plane.
    ETS-6 is spinning out of control, but I managed to find its orientation from
    observations in 1999 and 2000. My old data seem to fit with a few new
    observations, but this is more than expected. I will analyze this to see if
    I can make the model agree with this observation.
    When a spinning satellite with solar panels is passing anywhere on the track
    of the flash cone, its flashes can even be 1-power at distances like ETS-6
    apogee! The flash episodes are short duration if the satellite crosses the
    flash track at large angles, longer if they are nearly parallell.
    Please report times (and/or positions) of unusually bright flashes!
