IOTA/IOTA-ES occultation update for
(57) Mnemosyne / TYC 5237-00287-1 event on 2022 Jan 05, 12:52 UT
Visible from SE Asia
Summary
-------
On 2022 Jan 05 UT, the 115.7 km diameter asteroid (57) Mnemosyne will occult a
8.7 mag star in the constellation Aquarius for observers along a path across SE
Asia.
In the case of an occultation, the combined light of the asteroid and the star
will drop by 4.18 mag to 12.83 mag (the magnitude of the asteroid) for at most
3.410 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.
