Timings are in UT. To convert these into IST add 5 hours and 30 mins.

P: Phenomenon, R – Reappearance, D – Disappearance

Mag (v): Visual Magnitude of the star occulted.

CA: Cusp angle of the event. This is the number of degrees from the northern (N) or southern (S) cusp to the event. The positive (+) events occur on dark limb and are easiest to see; negative (-) events occur on bright limb. See the figure below.

PA: is the position angle measured in degrees. Similar to the position angle for double stars, it is the angle from due north (0°) to the point on the Moon's limb where the Event occurs. 90° is celestial east (to the left), 180° is celestial south, 270° is celestial west (to the right). See left figure below.
