Summary
-------
On 2024 Oct 11 UT, the 30.6411328885612 km diameter asteroid (4547)
Massachusetts will occult a 10.0 mag star in the constellation Lupus for
observers along a path across .
In the case of an occultation, the combined light of the asteroid and the star
will drop by 7.44 mag to 17.45 mag (the magnitude of the asteroid) for at most
0.830 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
