PLANETARY OCCULTATIONS:
AUSTRALIA & NEW ZEALAND - 1999

During 1999 there are about 100 minor planet occultation tracks which could pass over parts of Australia or New Zealand. For a summary of all predicted events click here.

The predicted tracks of a proportion of these events are especially favourably placed for observation from well populated parts of the region (e.g. southeastern Australia). These events have been targetted for "last-minute astrometry", in which an attempt is made to accurately update the original prediction only a few nights before the event.

The following table lists these specially targetted events. Complete predictions for all the events potentially visible from Australasia are available through the RASNZ Occultation Section's CA series of Circulars.


EXPLANATION OF THE TABLE
Update :
Click here for a recent update to the prediction.
Date and hour:
Universal Time (UT). UT is effectively equivalent to Greenwich Mean Time. In New Zealand, add 12 hours to UT to get NZ Standard Time, or add 13 hours to get NZ Daylight Time.
Minor Planet :
The number and name of the minor planet involved. Click for a prediction for the event.

Predictions typically take the form of an approximately 18k GIF file which contains tabular information about the minor planet and star, a world map showing the predicted track, and two star charts showing the star involved and the path of the minor planet several days prior to the event. For further information about interpreting the predictions click here.

Diam (km) :
The planet's expected diameter in kilometres.
Star Name :
Catalog name and number of the star being occulted. Catalog names are: HIP = Hipparcos; TYC = Tycho; PPM = Positions and Proper Motions; TAC = Twin Astrographic Catalog; GSC = Hubble Guide Star Catalog. Star positions in the Hipparcos and Tycho Catalogs are known to less than 30 millarcsecond accuracy. Hence HIP and TYC stars are likely to yield the most accurate predictions.
Star Mag :
Brightness of the star being occulted.
R.A./Dec :
Right Ascension and Declination of the star being occulted for Epoch J2000.
Del m :
The expected drop in magnitude (brightness) if the star is occulted. A drop in magnitude of about 0.6 is generally accepted as being at about the limit of human perception.
Max Durn :
Maximum expected duration (in seconds) of the occultation for a planet of the quoted diameter.
Pr :
The relative importance (Priority) of the event, and the likelihood "last-minute astrometry" will be obtained. Priorities have been assigned taking into account the size of the minor planet, star magnitude, Delta M, predicted region of visibility and population density therein, potential path error, and other factors. Priority 1 events have the greatest chance of being updated.
Region :
The expected region in which the occultation will be observed.
"A" = Australia; "NZ" = New Zealand; "PNG" = Papua New Guinea;
"s" = south; "n" = north; "e" = east; etc.
