    Re: Aldebaran occultation

    Using MICA, I arrived at a slightly different start time for the occultation as seen from Alexandre's given location. The times I get are:

    Start: 03:57:10 UT1 (16.134')

    Minimum: 04:17:31 UT1  (12.184')

    End: 04:37:24 UT1  (16.141')

    Also, I get a SD of the Moon of 16'08.27" at the time of occultation. This differs from Paul's figure by -8.13". Using a time of 03:57:10 UT1 (March 4th 22:57:10 UT-5, my time zone) gives a pretty good match in Stellarium.

    Incidentally, the IOTA bright star lunar occultation website gives a time of 03:56:48 UT1 for Indianapolis (line 391), exactly matching Alexandre's time.

    Regards,

    Sean C.
