Summary
-------
On 2024 Oct 15 UT, the 16.3021537591696 km diameter asteroid (2355) Nei will
occult a 9.6 mag star in the constellation Sagittarius for observers along a
path across .
In the case of an occultation, the combined light of the asteroid and the star
will drop by 7.61 mag to 17.25 mag (the magnitude of the asteroid) for at most
0.670 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.
