IOTA/IOTA-ES occultation update for (109) Felicitas / UCAC4-283-191217 event on 2023 May 16, 12:10 UT Visible from New Zealand, Australia Summary ------- On 2023 May 16 UT, the 87.4 km diameter asteroid (109) Felicitas will occult a 12.3 mag star in the constellation Sagittarius for observers along a path across New Zealand, Australia. In the case of an occultation, the combined light of the asteroid and the star will drop by 2.26 mag to 14.46 mag (the magnitude of the asteroid) for at most 9.980 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.
