    Re: Aldebaran occultation

    You say that your program is not very precise for occultations.
    Is there a simple way to compare my timing with some calculation ?
    Or I have to do all calculation by hand myself?
    P.S. This is the first time that I observe an occultation. I agree with Brad 
    that this is tiresome and cold:-)
    But the main conclusion I infer from my observation is that a binocular is absolutely necessary.
    There is no way to see a star approaching the Moon (1/2 or more) with naked eye.
    Binoculars (or "night glasses" are relatively recent invention, 18 century or so).
    Could people use this method in the earlier times by somehow obscuring (shielding) the Moon?

    While Wayne was observing from my secondary recommended location, I and 
    another student from this weekend's class, Paul M, as well as a highly 
    experienced occultation observer (from Massachusetts who drove down thanks to 
    my suggestion on Sky & Telescope's website) all watched from the parking lot 
    by the movie theater in South Kingstown, Rhode Island. Lots of fun. Saw 
    Aldebaran blink out and then back with my own eyes via binoculars. For the 
    remaining minute of the event, I watched on the video screen attached to our 
    guest's telescope which removed my shivering hands from the equation. We saw 
    several more clear vanishings and re-appearances. Very cool and lots of fun! 
    My thanks to orbital mechanics for arranging the occultation graze zone so 
    close to my backyard.
    For folks interested in treating this as a lunar, my lunar clearing web app is 
    not designed for occultations. It's question of sensitivity to individual 
    altitudes versus sensitivity to the difference in altitudes.
    We just took noon Sun sights at Stonington Point, by the way, and I am waiting 
    for the class to return from lunch break. Oh here are several of them now!
