Yesterday I got a 12 min opportunity to search photographically for Alexis,
not seen in 209 days. I have  #38758_#38773_#17528_#7727 and #23279 in 11
images, but there is the faintest track I ever tried to measure, in one or
two of them. It is roughly parallell to Alexis track, but about 4 deg W of
SGP4 prediction in the sky at 42 deg in NW, and about 100 s late.
Integrating an orbit with Advance.14 and correcting for time brings the
prediction less than 1.5 deg from the possible track.
But it is not exactly parallell to the prediction, and the (visible) track
is too short. The preceding image, with an even fainter track that doesn't
exactly line up with one below, and is too close to be at the Alexis
orbital height.
