An early India Section record of Saturn close to the lunar limb.

Observers at IUCAA, Pune timed the occultation using a Celestron C8 and a 3-inch refractor. The ear-and-eye timings were reported to David and Joan Dunham, with Jyotirvidya Parisanstha members participating.
An unusual predicted occultation from Pune was investigated through manual calculations and CCD observations at IUCAA. The brightness difference between Venus and the magnitude 8.5 star made direct timing difficult.

The event formed part of the early visual and photographic archive maintained by the India Section.


The observing team travelled north from Pune toward the GMRT region near Khodad to reach the event geometry and recorded the partial occultation.

A 180-second Canon 7D exposure, synchronized to NIST time, recorded a break in the star trail measured at approximately 11 seconds.

Five observing locations were selected to sample the asteroid shadow. One team recorded the occultation using a Skywatcher 8-inch reflector and Canon 5D Mark II.

An India team worked alongside experienced international observer Paul Maley near Delhi, using video equipment with synchronized computer and recorder timing.

The lunar emersion of Jupiter was observed at approximately 18:08 IST.
