Video sequence of the minor planet 8474 Rettig moving across the night sky.
I often participate in astronomical research by way of providing observations to other amateurs and to professionals. The promise is always there of credit for the observations but rarely has it actually eventuate in to anything published with my name on it. Here’s one from recently I’m happy to be involved in and credited for my participation (which was a small but useful contribution):

Mathematics, Moscow, report that photometric observations obtained during
May 19-July 23 reveal that minor planet (8474) is a binary system with an
orbital period of 30.54 +/- 0.01 hr. Mutual eclipse/occultation events
that are 0.60- to 0.93-magnitude deep indicate a lower limit on the
secondary-to-primary mean-diameter ratio of 0.86. Rotations of the
components appear to be synchronous with the orbital motion and an
amplitude of the combined primary plus secondary rotational lightcurve is
0.34 mag at solar phases 7-15 deg.
