IOTA/IOTA-ES occultation update for
(1126) Otero / UCAC4 594-040929 event on 2024 Oct 20, 09:37 UT
Visible from
Summary
-------
On 2024 Oct 20 UT, the 10.858 km diameter asteroid (1126) Otero will occult a
10.8 mag star in the constellation Gemini for observers along a path across .
In the case of an occultation, the combined light of the asteroid and the star
will drop by 5.16 mag to 15.92 mag (the magnitude of the asteroid) for at most
0.590 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
