Abstract. Observations of the occultation of the star 2UCAC 42376428 by
(423) Diotima on 2005 March 06 at the Vainu Bappu Observatory are reported.
The observed mid time of the event at 15:12:25.1 UT occurred 3.4 s later than
the predicted time but within the 1 uncertainty of 4.3 s of the predictions
by IOTA. The duration of the event of 4.2 s was found to be shorter than the
predictions even allowing for a one sigma uncertainty in the impact parameter.
This implies a narrower projected width of the asteroid along the occultation
track at the time of the event.
