BRIGHT GRAZING OCCULTATIONS:
NEW ZEALAND - 1999
- Note:
- 'S' at the end of a track indicates interference from the Sun
- 'A' indicates that the star is at low altitude
EXPLANATION OF THE TABLE
- Date :
- 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.
- Star :
- ZC indicates the star number in Robertson's Zodiacal Catalog.
- S indicates the star number in the SAO Catalog.
- Mag :
- Star Magnitude.
- Time :
- Approximate hour and minute of graze (Universal Time) for a longitude about the middle of the map. For sites to the west times may be a minute or so earlier whilst to the east they may be a little later. Events may occur
for a minute or two either side of the predicted time.
- %Snlt :
- Percent sunlit of the moon. "+" is waxing (before Full Moon) and "-" waning. Before Full Moon the star will appear to approach the moon from its dark side. After Full Moon the star appears to approach across the lighted lunar limb.
- CA & Limit :
- The Limit indicates whether the star grazes the Northern or Southern edge of the Moon. The associated figure shows the number of degrees round the circumference of the Moon from the bright cusp at which mid graze occurs. The centres of all grazes given above are on the unlit portion of the limb.
- Notes :
- If the grazing star is a double, quantities given are: the magnitudes of the components, the separation in seconds of arc, and the Position Angle of the secondary component from the primary.
- Prediction for... :
- An entry here indicates IOTA Predictions and a profile are available as a text file for this graze. Once downloaded and saved, you should view the file with a non-proportional font (e.g. Courier 10 point) to preserve the formatting.
