This difficult event may be visible from eastern regions of Australia. The event is not included in Goffin's predictions and was only identified in a search for possible occultations following the discovery of Eugenia's satellite.


UPDATE : 9 May 1999

This prediction has been identified and calculated by Jan Manek of the Stefanik Observatory, Prague. The prediction is based upon 29 USNO, 16 TMO and 54 CAMC astrometric positions obtained between 1989 September 26 and 1998 December 12. The ACT position of the star has been used for the prediction.

Manek notes that the event will only be visible from a very narrow part of Pacific coast of Australia due to unfavourable twilight conditions; in fact the Sun will only be about 8 degrees below the horizon. The position of Eugenia's natural satellite is not known so it is not possible to prepare a path prediction for this.

NOTE: The chance of seeing this event is only marginal; CONDITIONS ARE FAR FROM FAVOURABLE.

Eugenia Update 1

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.
