Discussion:
The circle above is plotted at the expected 45 km diameter of Regina. With two chords we can be reasonably sure that the plot represents a good estimate of the event location.
The figures below shows the lighcurve of Jonathan Bradshaw's chord of the occultation from Limovie software.

At mv 12.0 in bright moonlight the image could be 'held' but not with ease, to the extent that if there had been a 0.2 second event, it could have been missed. However the event was obvious and I don't think I glimpsed the asteroid during disappearance. The star just 'went out'. I know this sounds silly, but if it is not obvious you are concentrating on waiting for the reappearance a few seconds later rather than trying averted vision if the asteroid is not obvious. This period is one of heightened tension with the comparison star continually being monitored because this references the position of the occulted star. _______________________________ Observer Jonathan Bradshaw Location Samford, Queensland, Australia Longitude +152:52:22.7 Latitude -27:21:22.8 Altitude 95 m Datum WGS84 Telescope Dobsonian Aperture 50 cm Seeing Steady Clear Timing GPS - time inserted Video with frame analysis Disappearance 13:05:52.14 Reappearance 13:05:55.62 Comments: An unexpected treat!
