IOTA/IOTA-ES occultation update for
(785) Zwetana / TYC 1918-00430-1 event on 2024 Oct 25, 04:28 UT
Visible from
Summary
-------
On 2024 Oct 25 UT, the 50.3199120799669 km diameter asteroid (785) Zwetana will
occult a 11.2 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 3.36 mag to 14.51 mag (the magnitude of the asteroid) for at most
4.460 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.
