Comment : Of these there is one interesting observation by Anthony Stokes, which is ~50km north of
the probable north limit. This may be a evidence for a small satellite of (791) Ani, however there exist important negative observation
by Chris Hooker, which is only ~4km south of the Stokes's positive observation. The nature of this satellite is therefore unsure,
other explanations of Stokes's event are possible.
Other 7 observations were reduced and preliminary plot is here (red circles represent D and green R - these are
connected by a white line; lone green circles represent negative observations). There jumps out of line one observation which is
systematically late by 3 seconds, having good duration (Chris Morse), however this correponds to the fact as he noted
"This may be a few secs. out." as he could measure only duration on his stopwatch and absolute time were merely estimates than measurements.
Also Roger Dymock's disappearance seems to be some 2 seconds late as it can be compared to Quinn's and Morse's duration - they were all
almost exactly on such places that the chords overlap. As Frank Leiter and Klaus Spruck observed on the same place so there are finally
in fact 'only' 4 chords which can be used for preliminary analysis. The asteroid's profile is rather squezzed with dimension ~100x65 km.

Comment : Ricard Casas notes : HIP 66600 is a double star with the secondary star at 18" in
PA 2d, and there is "anything" similar to nebula around the system (?).

Comment : Clouded report came from Marek Zawilski (PL). As you can see the event was not observed anywhere.
Unfortunately on two Slovak stations were observations completely aborted by weather: Humenne (48 57 N, 21 55 E; Michal Maturkanic) - clouds came
only 0.5 hour before event) and Kysucke Nove Mesto (49 18 N, 18 46 E; Jan Masiar) fog came also 0.5 hour before event. Both were on very
important places wrt. updated path.

Comment : Oscar metiones that it is possible he could have missed the actual occultation because there were
no suitable reference stars around for this low-amplitude event.

Comment : Stefano Sposetti provided kindly his drift scan CCD image, which I have annotated.
Reduction is only preliminary now. Positive observation (under bad conditions) of Carlos Labordena doesn't agree with other reports. Claudio
Cremaschini must have missed the occultation. Negative observation comes from Wolfgang Beisker; no detailed report yet.
