IOTA/IOTA-ES occultation update for
(45481) 2000 AK233 / TYC 4697-00255-1 event on 2024 Oct 21, 23:14 UT
Visible from
Summary
-------
On 2024 Oct 21 UT, the 14.0698334423641 km diameter asteroid (45481) 2000 AK233
will occult a 9.8 mag star in the constellation Cetus for observers along a
path across .
In the case of an occultation, the combined light of the asteroid and the star
will drop by 6.65 mag to 16.43 mag (the magnitude of the asteroid) for at most
1.690 seconds.
This update is based on, astrometry for the asteroid kindly provided by the IAU
Minor Planet Center.
This work has made use of data from the European Space Agency (ESA)
mission Gaia (http://www.cosmos.esa.int/gaia), processed by the
Gaia Data Processing and Analysis Consortium
(DPAC, http://www.cosmos.esa.int/web/gaia/dpac/consortium).
Funding for the DPAC has been provided by national institutions, in
particular the institutions participating in the Gaia Multilateral Agreement.
