Event Rank : 72

(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).


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.

Bressole Update Map

On 2017 Jan 28 UT, the 46 km diameter asteroid (1211) Bressole will occult a 10.7 mag star in the constellation Cetus for observers along a path running near New Zealand.

In the case of an occultation, the combined light of the asteroid and the star will drop by 5.61 mag to 16.30 mag (the magnitude of the asteroid) for at most 2.8 seconds.

This update is based on UNSO/Flagstaff astrometry for the asteroid kindly provided by Hugh Harris, 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 (, processed by the Gaia Data Processing and Analysis Consortium (DPAC, Funding for the DPAC has been provided by national institutions, in particular the institutions participating in the Gaia Multilateral Agreement.
