IOTA/IOTA-ES occultation update for
(726) Joella / TYC 1337-01224-1 event on 2006 Aug 23, 20:36 UT
Visible from China
Summary
-------
On 2006 Aug 23 UT, the 44 km diameter asteroid (726) Joella will occult a 7.6
mag star in the constellation Gemini for observers along a path across China.
In the case of an occultation, the combined light of the asteroid and the star
will drop by 7.9 mag to 15.5 mag (the magnitude of the asteroid) for at most 1.3
seconds.
This update is based on UNSO/Flagstaff astrometry for the asteroid kindly
provided by Ron Stone, historical astrometry from the MPC files (via AstDys),
and the following catalogs for the star position: .
