419 Aurelia Occultation - Report from Adelaide

We had broken cloud here all the way up to the event time, so it was really difficult to get the telescope set up and aligned properly. Add to that a problem with the preparation of the finder chart (it was printed mirror imaged and reversed!), and we didn't start the drift image capture until too late. Anyhow, here it is:

You can see it was not a complete loss, we still got the end time of the event, and an upper bound on the start time. From manual measurement of the drift image, we got Tstart < 12:53:34.5 UT and Tend = 12:53:37 +/- 0.5s UT.

Our location was S 34 53 04.2 E 138 37 51.3, Elev 44 m.

Perhaps the data point is of some scientific value. I wish we had got the image started even just 10 seconds earlier!

Anyway, there's always next time!
