The shadow of 34km diameter Roccapalumba passed across my home location where i was able to record it occult the star with my C11. ( Prediction with Occult4 software and Gaia data release).   I was using a USB3 camera at 80ms exposure.  There was a good opportunity to set up a mobile telescope to get second set of observations from a position near the middle of the shadow.  The star was 10.7 magnitude and well placed near the head of Hydra.

I used a second telescope (EQ6) with a 4.5" Helios refractor. The C11 was set to start a scheduled recording while I drove about 11 miles to a carpark to set up the refractor and video camera. (pictured)

The inset show the two light curves overlapped. The 120mm is the more noisy recording and the duration is longer.  The duration times were 1.36 sec and 2.00 sec

I believe this is the first report of a dual-chord asteroid observation by single UK based observer. (Not the first world-wide though.)   There may be other opportunities coming up.  For e.g. (212) Medea on Jan 21    https://britastro.org/node/26482
