[Prediction by Edwin Goffin]

[Prediction using OCCULT software]

[Detailed finder chart by Jan Manek]

Goffin's predicted path crosses the southern Western Australian coast just east of Esperence passing to the northwest leaving the coastline in the Karratha/Onslow area. The path predicted by OCCULT lies around three path widths to the east crossing the coasts near the South Australia border and exiting near Pardoo east of Port Hedland. There is little difference in the predicted times for the two paths.


UPDATE: 26 April 2000

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.

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.
