[IOTAoccultations] NOMAD_SHORT Star Catalog for OCCULT v4 - Important
--====----====----====----====----====----====----====----====----====----===--
 
Everyone-
 I can now successfully burn DVD copies of the Dave Herald edited version of
 the NOMAD catalog. This catalog is intended for use with OCCULT v4  to
 search for asteroid events and is intended to be distributed with OCCULT
 when it is released. I am helping out with both distributions since I am in
 this hemisphere of the planet..
 OCCULT is not yet on the disc. Even if they both fit on one DVD, when the
 time comes I will be providing OCCULT and NOMAD_SHORT on separate discs as I
 think a star catalog should be on its own disc.. Obviously that may change
 depending on how Dave wants it sent out, if it fits on one disc, etc...
 
 The catalog is copied in its entirety to a DVD +RW disc and verified that it
 is an exact duplicate of the original.
 
 Anywho.. Now that I can make distribution DVDs, my question is who wants
 one? I am primarily distributing to North America, but if you send me a self
 addressed CD Mailer, I will send you a copy. Please send me a direct email
 and I will send you an address to mail the CD Mailer to. If you would like
 to send TWO mailers now, I will save the second mailer for when I send out
 OCCULT v4..

Then on Sept. 27, around 14.8 UT, the Earth will pass between the
shadows of Pluto and Charon, with no occultation by either object visible
from Earth's surface, involving the 8.7-mag. (!) star SAO 160793 =
UCAC2 17h 44m 38.4s, Dec. -16 deg. 46' 35"; the night area of
possible occultations by Plutonian rings being most of Asia
(from Arabia to Vietnam to western & southern China to the Ural
Mountains, the Horn of Africa, western Australia, part of
Antarctica, and the Indian Ocean.

[PLANOCCULT] Possible occn. by the double Centaur
:    2002CR46.GIF
--====----====----====----====----
>From J.Lecacheux.

I searched for occultations by the 42355 Centaur -just that
one newly identified as double- in the 2006.1-2010.0 interval.

I found none, excepted a near miss on 2006 March 21.99, i.e. only one month ahead :

The occultation of the faint rUCAC= 14.2 star 2UCAC 36297026 should miss the Earth by ~ 1100 km, but a modest 0".2 shift (i.e. about one AstDys sigma) toward the south-west would be able to put the occultation path across central Europe between 23:40 and 23:43 UT ( some minutes).

Note that the HST measured 1330 km between the primary and the satellite at the discovery instant. This distance should vary between unknown limits because of the orbital motion of the asteroidal satellite, but nevertheless this is comparable to the above miss distance to the Earth.

Possible occultation duration : 6-12 seconds, if the size of the body is in the 100-200 km range as it is currently estimated.

I think that the best-equipped observers in Europe should try this uncertain and difficult event.
