This prediction update is supplied by Jan Manek of the Stefanik Observatory, Prague, and is based on USNO/Flagstaff astrometry for the minor planet and the TYC-2 star position.
Summary:
This update places the path around 0.4" to the north-east of the path given by Goffin near that given by OCCULT and about 40 seconds earlier. The path runs now just to the west of Tasmania (19:48 UT), crosses the Western Australian southern coast just west of the South Australia border (19:52:50 UT) passing to the north-west crossing the coast again just to the east of Port Hedland (19:55:15 UT). The path then crosses Java and Surakarta (15:59 UT) and between Borneo and Sumatra (20:10 UT). The path then crosses Thailand east of Krungh Thep (20:04 UT) before crossing eastern Burma, far eastern India, central China and Russia at low altitude.
The target star is the brighter component of the double star STN 34. See further comments below.
THE EVENT AT ONE GLIMPSE:
IMPORTANT NOTE!
Astrometric updates such as these should not be taken as definitive, but rather only as an indication of where the true track may lie relative to the original predicted track. Observers must bear in mind that later astrometry, in which the target star is measured in the same field as the asteroid, may still reveal substantial changes to the predicted track and time of the event. For this reason it is most important that observers far from the predicted track still monitor the event.
