IOTA/IOTA-ES occultation update for (122) Gerda / UCAC4 391-131759 event on 2022 Jun 22, 04:03 UT Visible from Europe Summary ------- On 2022 Jun 22 UT, the 78 km diameter asteroid (122) Gerda will occult a 12.3 mag star in the constellation Capricornus for observers along a path across Europe. In the case of an occultation, the combined light of the asteroid and the star will drop by 1.34 mag to 13.22 mag (the magnitude of the asteroid) for at most 53.870 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.
