IOTA/IOTA-ES occultation update for (931) Whittemora / UCAC4 406-065090 event on 2023 May 12, 15:19 UT Visible from Australia Summary ------- On 2023 May 12 UT, the 45.9 km diameter asteroid (931) Whittemora will occult a 12.2 mag star in the constellation Scorpius for observers along a path across Australia. In the case of an occultation, the combined light of the asteroid and the star will drop by 2.84 mag to 14.99 mag (the magnitude of the asteroid) for at most 2.910 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.
