Wasn't It six months ago we were talking about how LOW the moon was?

Anyway this wasn't as straight forward as I thought. SkyMap's Ephemeris
doesn't calculate extremes of altitude, so I ran an ephemeris for =
extremes
in declination, eliminated the southerly extremes. Then I looked up the
transit times for the days the moon reached the Northerly extreme in =
Dec,
set the time to the transit and looked up the altitude. The results =
below:

Date (UT)                    Dec                     Alt

2007 Aug 08 23:11       +28=B0 20' 23"  +84=B0 29' 56"

2007 Oct 29 18:29       +28=B0 06' 58"  +84=B0 14' 49"
2007 Mar 25 05:54       +28=B0 34' 53"  +84=B0 13' 17"
2007 Jun 15 08:32       +28=B0 12' 37"  +84=B0 13' 05"
2007 Nov 26 04:11       +27=B0 57' 20"  +84=B0 08' 35"
2007 Dec 23 14:32       +27=B0 54' 57"  +84=B0 02' 17"
2007 Apr 21 13:49       +28=B0 26' 44"  +82=B0 49' 12"

Looks like this months moon is actually near the low end of the scale, =
Last
month was the winner , only 5=B0 10' 10" from the zenith, at least from =
my
house :)

Hello everybody,

So who has the answer:  old Luna is looking pretty straight-up right =
about
now.  What is the max altitude for tonight or for this month for that
matter?

Thanks,

Matt
