I logged observations of three asteroids during an observing session on the evening of November 19th between 8:30pm and 11:00pm PST. When I look at the observations for that session now (the evening of 11/30), all the asteroid names have changed!
"(3) Juno" became "S-NET D" (I think, this might possibly have been an observation of "(647) Adelgunde" that was changed to "S-NET D")
"(433) Eros" became "(427) Galene"
"(456) Abnoba" became "(450) Brigitta"
"(293) Brasilia" became "(287) Nephthys"
These all looked fine the night of the observing session, and just noticed the change tonight. Did a subsequent update to my SS6 minor planet database somehow corrupt this?
