BRIGHT STARS OCCULTED BY THE MOON
AUSTRALIA - 2012

Sydney, Canberra, Melbourne and Hobart


EXPLANATION OF THE TABLE
Date :
Universal Time (UT). UT is effectively equivalent to Greenwich Mean Time.
ZC :
Star number in Robertson's Zodiacal Catalog.
Mag :
Star Magnitude.
Ev :
Event, either a Disappearance of the star behind the edge of the Moon, or a Reappearance of the star from behind the lunar limb. Almost all events listed take place at the dark limb. Disappearances occur before Full Moon when the Moon's eastern limb is dark. Reappearances occur after Full Moon when the Moon's western limb is dark.
% :
Percentage of the moon illuminated; "+" indicates waxing and "-" waning. "E" indicates that the event occurs during a lunar eclipse with the number representing the amount of moon outside the umbra.
City Name :
Time of the occultation at the named locations, expressed in hours and decimal minutes of Universal Time. Because the actual time of an event depends very much on the observer's physical location, times given are approximate and may vary by a minute or two across a distance of several tens of kilometres. "no occultation" indicates that no occultation will be visible from that site. "Graze" indicates that there is a grazing occultation close to the site, and occultation times will vary dramatically or may not happen at all.  Green text indicates that the event occurs at an altitude less the 15 degrees.  Red indicates that the event occurs with the Sun less than 10 degrees below the horizon.  Magenta indicates that both conditions are current. 

Note: For detailed information about interesting graze events in Australia refer to [Grazing Lunar Occultation Predictions for Australia - 2012]

CA :
Cusp Angle, or angle around the moon's limb at which the occultation occurs. This is measured from the Northern or Southern cusp of the Moon in the direction of the unlit part of the Moon.  If CA is negative this indicates that the event will be against the sunlit part of the moon and will probably require a large telescope to be observable.
Notes :
For a double or triple star, the magnitudes of the components and the separation in seconds of arc.
For a variable star, the magnitudes between which the star varies.
