ASTEROIDAL OCCULTATION ON WEDNESDAY 24 SEPTEMBER
By Jon Harper
Occultation Section Director
Asteroidal Occultation of TYC 0633-01047-1 by (56) Melete on Wednesday
24 September at around 22h 36m UT in UK: an interesting event of
reasonable length. The m(v) 10.9 star lies just inside Aries near its
boundary with Cetus and Pisces, at
R.A. 2h 5m 38s.9, decl +10d 59' 31".2 (2000)
Altitude at time of occultation about 32 degrees, azimuth around 120
degrees (ESE/SE).
Melete will be at m(v) 11.8 and may be detected before and after the
occultation in the vicinity of the star. The duration of the
occultation at the central line is estimated to be around 14 seconds,
but will of course be less the further you are from the centre line.
Observers should expect to see a drop in the combined light of the
asteroid and star of around 1.3 magnitudes.
The wide occultation path crosses the UK from north-eastern England to
the south coast, crossing the country between 22:36 and 22:37 UT.
You should set up in good time and find the star. It is a good idea
to start watching the star for any occultation a couple of minutes
before the predicted time. If you would like to observe the event,
and require a star chart of the area, please drop me an e-mail.
I will be happy to send one by return as an attachment for you to
print out. I also have the most up-to-date occultation path generated
by Occult Watcher and Google Earth available too, again please
request. (jonvran@aol.com)
If you intend to do a timing please download a report form from the
SPA Occultation Section's web site :

You will find examples of how to fill the forms in on the same page.
If you require any further help please ask. Please let me know how
you get on, and if you do attempt a timing I will be happy to receive
your results.
