ASTROMETRIC UPDATE:
OCCULTATION BY (403) CYANE - 2021 FEB 03

[Edwin Goffin's Prediction + Finder Charts]

[Detailed Finder Charts]


Updated:   2020 Dec 31, 01:01 UT

Event Rank : 98

(The event Rank is a measure of the likelihood of observing an event, and is equal to the probability of at least one successful observation by a team of two observers spaced 1/8 path width just inside opposite sides of the predicted path. An event rank of 100 indicates that the prediction is expected to be very accurate).


THE UPDATED PATH

Note: The duration given in the line below is the interval during which the occultation shadow sweeps across the Earth - please see the minute markers on the map to determine the approximate time for your location.

Cyane Update Map


On 2021 Feb 03 UT, the 48 km diameter asteroid (403) Cyane will occult a 12.0 mag star in the constellation Orion for observers along a path across north-western New South Wales, southern Queensland, northern South Australia and southern West Australia, running from Geraldton to Casino.

In the case of an occultation, the combined light of the asteroid and the star will drop by 1.36 mag to 12.94 mag (the magnitude of the asteroid) for at most 9.2 seconds.

This update is based on UNSO/Flagstaff astrometry for the asteroid kindly provided by Hugh Harris, astrometry for the asteroid kindly provided by Bill Owen, 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.
