ASTROMETRIC UPDATE:
OCCULTATION BY (59905) 1999RB151 - 2021 Jul 18

[Detailed Finder Charts]


Updated:   2021 MAY 29, 00:23 UT

Event Rank : 24

(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.

1999RB151 Update Map


On 2021 Jul 18 UT, the 10.0907574049891 km diameter asteroid (59905) 1999 RB151 will occult a 5.7 mag star in the constellation Capricornus for observers along a path across Australia from Port Lincoln across south-eastern South Australia in early morning twilight and into north-western New South Wales and southern Queensland in morning twilight and at decreasing elevation.

In the case of an occultation, the combined light of the asteroid and the star will drop by 12.56 mag to 18.26 mag (the magnitude of the asteroid) for at most 1.1 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, inparticular the institutions participating in the Gaia Multilateral Agreement.
