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 (Before March 19 and after October 1).

ZC :

Star number in Robertson's Zodiacal Catalog.

Mag :

Star Magnitude. "V" indicates that the star is slightly variable.

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. 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 a lunar eclipse.

Auck/Well/Chch/Dudn :

Time of the occultation at Auckland, Wellington, Christchurch and Dunedin, 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 Occult" indicates that no occultation will be visible from that site. "Below Hor" indicates that the moon is below the horizon at the time of the occultation. "Daylight" indicates that the sun is above the horizon at the time of the occultation. "Graze" indicates that there is a grazing occultation close to the position and occultation times will vary dramatically over small distances or may not happen at all. Green text indicates that the event occurs at an altitude less than 15 degrees. Red text indicates that the event occurs with the sun less than 10 degrees below the horizon. Events can have both conditions current.

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.

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.

Notes on Events

May 11, disappearance of ZC810 this is a daytime event.

June 16, occultation of Jupiter and its satellites. These are extended objects, so events are prolonged:
Jupiter will take 2 or 3 minutes to be completely obscured, the satellites a few seconds.
The reappearance of Jupiter is at the bright limb as is the partial graze visible from Dunedin.

September 22, the stars occulted are in the Pleiades. Note that the order of occultation of the stars varies from place to place.
