IOTA/IOTA-ES occultation update for (914) Palisana / UCAC4 546-129980 event on 2023 Jul 13, 22:08 UT Visible from Africa Summary ------- On 2023 Jul 13 UT, the 82 km diameter asteroid (914) Palisana will occult a 11.6 mag star in the constellation Delphinus for observers along a path across Africa. In the case of an occultation, the combined light of the asteroid and the star will drop by 0.85 mag to 11.78 mag (the magnitude of the asteroid) for at most 7.130 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.
