IOTA/IOTA-ES occultation update for
(93) Minerva / 2UCAC 43944479 event on 2011 Jan 28, 10:13 UT
Visible from USA, Japan
Summary
-------
On 2011 Jan 28 UT, the 170 km diameter asteroid (93) Minerva will occult a 12.9
mag star in the constellation Auriga for observers along a path across USA,
Japan.
In the case of an occultation, the combined light of the asteroid and the star
will drop by 0.6 mag to 12.6 mag (the magnitude of the asteroid) for at most
15.7 seconds.
This update is based on UNSO/Flagstaff astrometry for the asteroid kindly
provided by Alice Monet, TMO astrometry for the asteroid kindly provided by Bill
Owen, historical astrometry from the MPC files (via AstDys), and the following
catalogs for the star position: UCAC.
The event at a glimpse

* magnitude drop [mag]: 0.6
* estimated maximum duration [s]: 15.7
* Moon: 30 % sunlit, 145� distance
