This event lasted roughly 10 seconds. As far as I know no one else captured this event with CCD or other device. A friend of mine, Andrea Manna, observed visually at about 10km distance and confirmed the occultation. The field of view is about 20 x 20 arcminutes. In the gif-animated file one can see Diotima roughly 30 minutes before and 50 minutes after the occultation.
North is up.
