Hello Troy,
You're welcome! Regarding the reporting of the upcoming full moon (and
associated clamor), a very good local paper, The San Jose Mercury, today
reported, see URL and snippet below, that the 1912 full moon was
actually a far brighter moon. I don't know, perhaps 0.2% is far
I decided to get out xephem 3.0 and do some calculations for the
upcoming solstice/lunar perigee/full moon. Times are Mountain
Standard Time (UT - 7).
According to the xephem's solver, here are the time and other values
at the solstice (I found this by using the solver to minimize the

Thanks for the very detailed explaination Luke. So is the answer 27.2%
brightness difference between the June Moon and the Dec. Moon? That would
mean the paper was wrong. The newspaper also predicted the January Moon
would be even brighter (something you didn't cover).

Last night, I was looking at the moon. It was noticibly larger than the
night before. This was easy to judge, as it was very close to Jupiter and
Saturn which help as size references. These planets look to be about 10
degrees apart. So looking at the moon again tonight, it will be easy to

I'm not sure of the exact time of Full Moon, but according to my Psion the
declination at midnight will be 19deg26min.
I hope that helps!

Roger,
I hope the information below is helpful. Note that because the moon is
so close there is an offset between the true geocentric coords. and
the apparent or topocentric coords., this effect is termed geocentric
parallax. See chap. 39 in Meeus for more details. The topocentric values

When planning your solstice celebrations, the lunar perigee will be an
additional focus this year. An interesting point is that your sundials will
act as moondials on that night when the moon is full. The location of the
moon is directly opposite the sun so the time is displaced by 12 hours. By
almanac lost...there is a program that will do this..i'll see if i can find it
