IOTA/IOTA-ES occultation update for (914) Palisana / UCAC4-530-137586 event on 2023 Jul 03, 22:56 UT Visible from Europe, Arabia Summary ------- On 2023 Jul 03 UT, the 82 km diameter asteroid (914) Palisana will occult a 12.4 mag star in the constellation Delphinus for observers along a path across Europe, Arabia. In the case of an occultation, the combined light of the asteroid and the star will drop by 0.53 mag to 11.89 mag (the magnitude of the asteroid) for at most 6.490 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.
