    Re: Help with Lunar distance.
    From: Dave Walden
    Date: 2010 May 13, 14:10 -0700

    Here's what I think we know: a lunar distance of about 7 deg was observed from quite near 36-48S, 174-46E at close to 18:15:52 GMT. The Moon and Jupiter altitudes were calculated by a program apparently associated with tecepe.com.br.
    The moon passed Jupiter on 9 May 2010 GMT. At the first time when the lunar distance was about 7 deg, Jupiter and the Moon were below the local horizon.

    Possiblities: The GMT data was in fact 9 May. The 8 May date gives an LD quite a bit too big. The fact that the same LD occured twice in one day may have confused the tecepe software. It took the first occurance, calculated incorrect altitudes, (the negative altitudes may not be handled? that may also affect the pointed out incorrect sign of the PA correction?) The observation may have been far limb to far limb. If so, the discrepency seems about 10 min in LD observation, or about 30 min in observation time, or some combination.
