IOTA/IOTA-ES occultation update for (1952) Hesburgh / UCAC4 601-040109 event on 2020 Dec 16, 04:52 UT Visible from S USA Summary ------- On 2020 Dec 16 UT, the 37.8 km diameter asteroid (1952) Hesburgh will occult a 12.1 mag star in the constellation Gemini for observers along a path across S USA. In the case of an occultation, the combined light of the asteroid and the star will drop by 2.52 mag to 14.55 mag (the magnitude of the asteroid) for at most 3.3 seconds. This update is based on UNSO/Flagstaff astrometry for the asteroid kindly provided by Hugh Harris, 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.
