OCCULTATION OF REGULUS BY (166) RHODOPE OCTOBER 19th 2005

As I mentioned in my address to SPA members on Saturday,15th at Cambridge, the above event was due to take place in 4 days time, and that Anthony Ayiomamitis, a SPA member, had gone to his home town of Athens in order to attempt an observation of a rare asteroidal occultation of a bright first magnitude star. I am plesed to post the e-mail I received from him this morning together with my reply.

Dear Jon,
I would like to thank you VERY much for making all of this possible.I need some rest but I promise to follow-up in a few hours.
Be well!

Anthony.

Anthony'a Initial Report:

The occultation of Regulus by 166-Rhodope was observed successfully
approximately 40 minutes ago. I have captured an AVI video sequence of
the event and I will follow-up in a few hours with additional
information and results.

Using a frame rate of 20 fps (Philips ToUCam Pro 740) and an
Astro-Physics AP160 refractor, I managed to record 41 frames from the
first drop in magnitude for Regulus to the reappearance of partial
magnitude. The predicted time of the occultation for the center of the
predicted path was 1.1 seconds ... HOWEVER, I have a result which
suggests approximately 2.1 seconds and with my observing location lying
approximately 6 km from the predicted center.

Here is my reply:

Oh very well done, Anthony!.We in the SPA Occultation Section are very proud of your achievement ---and as a result we now have another person in this section who has observeda positive asteroidal occultation event --- and what a special one that was! I'm sure you will remember the day Regulus went out, for ever. With very best wishes, Jon
