IT DID IT AGAIN : THIRD and LAST attempt since some text by the end of my post got suppressed on first two trials. This time, I have slightly modified the arrangement of the end of my text, and did not include the Annex which was transmitted OK on the first 2 trials. Will it go thru entirely this time ???

Dear Hewitt,

You wrote : "Looking at Kermit's results, I'd say he used the 6-30-2009 date."

I will reply as follow :
YES ! I used the 6-30-2009 (UT) date, with LT-UT = +9 , which was subsequently confirmed as correct by Jeremy.

And for the time of the Moon Transit (UT=09h51m39.7s), I am getting the following data for the Moon :

GHA = 229°56'3 with RA hourly change = +0°.5064 and

DEC = S-12°38'7 with DEC hourly change = -12'.86

The actual Moon declination on 6-30-2009 was (much) further to the South than what Jeremy first indicated : QUOTE The declination is about 7 degrees south UNQUOTE, which tells us that Jeremy's clue would actually have been more appropriate for 6-29-2009 as you say, but it was nevertheless quite "valid" for 6-30-2009 in the sense that the Moon was - for both dates - South of the 6-30-2009 Observer's Position.

Hewitt, since in your subsequent post (RE : http://www.fer3.com/arc/m2.aspx?i=115508) you indicated : QUOTE Thanks, Jeremy,, that clears it up nicely, -Hewitt UNQUOTE, which results are you getting for this Moon LAN ?

I would guess that all of us - yourself, Peter, Andres, Kermit, and others - should derive (almost) the same end result (see my enclosed listing of entries and results : NOT INCLUDED IN THIS THIRD SENDING TRIAL), even with a plain parabolic fit to Jeremy's data which certainly should be fully appropriate here given both the "moderate" (55 degree) Culmination height and the rather "tight" (+/- 12 minutes of time) time-span around Culmination Time in this specific example.

Best Regards

Kermit

LAST NOTE TO THE ATTENTION OF FRANK E. REED : Now and then, I have noticed that some of my posts get "shortened/abridged" by your NavList Computer system. Any clue or reason for that, Frank ?
