Dear David,

Thank you very much for making my mouth water through offering me the opportunity of computing an upcoming star occultation by the Moon.

I have computed results WITHOUT Limb shape corrections. For Mar 21, 2010 with deltaT=66.8s I find the following results as seen from the new USNO in DC :

Immersion at UT=01h46m42.2s and Emersion at 02h48m18.9s, to be compared with your more accurate results with the same "no Limb shape correction" assumption :
UT=01h46m45s and UT=02h48m20s

I would think that the main reason for the (slight) lack of accuracy in my computations comes from the Moon apparent coordinates which - for lack of programming space - I can compute with an accuracy of only 4.5 arc seconds on my handheld calculator (4 sigma error), which is anyway more than sufficient for conventional CelNav and Lunars too...

Unfortunately for us people living here, this star occultation will not be visible from our "Belle France"

Thank you and Best Regards

Antoine M. "Kermit" Couëtte

For the fun of it ... - Paul, are you here ??? :-))) - I get the following apparent coordinates for NSV 1321, as computed from ICRS(2000) data with the P03 Precession series(IAU 2006) and the full Whar's Nutation series which were in use for some 20 years from 1984 onwards :

RA = 03h48m57.5808s , including a Gravitational Deflection correction of +0.0005s, and

Delta= N+23°27'12.191" including a GD correction of +0.0019"
