TAROT (Acronym for “Télescope à Action Rapide pour les Objets Transitoires”) is an automatic telescope, located at Calern Observatory, dedicated to g-rays bursts optical study;
when available, it can be used for various survey programs.

GHD : videorecording, observation was only partial due to clouds and dawn; BEI, FAR, HCP, MNK, OKE, PAR : videorecording.
HCP was in the predicted shadow path, near its southern border, MNK was situated 16km north of his predicted northern limit : there has been a slight shift (0.2 path width) of the shadow path toward north, relative to the prediction.
An unrealistic -18 s correction must be applied to BEI timing, to fit with the other mid-events. More probably, BEI blink is not a real event, as it is not confirmed by HCP, PAR and SHI, situated nearly on same chord, and even if HCP and PAR reported they could have miss “a 0.2 to 1 s duration event”. The other positive observations (except KHL’s one, see here after) can be fitted with a 129 ´ 82 km elliptic profile, with long axis parallel to asteroid motion, what is consistent with the 110 km mean value used for calculations. OKE missed the northern limb by 15 km.
On 2000.06.17, was observed from New-Zealand, an occultation of HIP 84192 by (164) Eva that let think this asteroid possibly have a satellite. Alan THOMAS and Clive ROWE registered occultation (5.8 and 1.5 s duration, respectively) but Brian LOADER and Lionel HUSSEY laying between the two, saw no event. Consequently, ROWE’s observation, if real, is possibly an occultation by a satellite (at least 25 km in diameter). (All information by courtesy of IOTA)
KHL present observation, if real, is irreconcilable with others (his chord is at about 90 km from the southern limb and occurred 43 s sooner than the predicted appulse time for his location). So he perhaps observed a 10 km chord of the hypothetical satellite.

JVA : videorecording, two drops of about two magnitude; PAR : videorecording, observation was disturbed by clouds.
LEI and PAR were in the predicted path but registered no event longer than 2 s.
The duration of the two events recorded by JVA are each close to the maximal value (132 s), which is a problem : one of them is obviously an artefact, if not the two, as the appulse at the JVA location occurred at 01:37:15 UT. The wide shift of the shadow path toward west (nearly 2 path widths) needed to explain one event only would be unlikely.

FMY : CCD imaging; FRP, SCB : videorecording; PUM, ROY : CCD drift-scan.
FRP transmitted a negative observation by COF.
(22) Kalliope is known to have a satellite S/20018 (22)_1 (Linus). Its track was predicted to run about 800 km south of the main body path, i.e. over Greece, Sardinia and the northern part of Spain. All the observers failed to observe any event in relation with this 36 km body.
The event observed by FMY is an occultation by the main body Kalliope itself.
According to the 3D model developed by J. BERTHIER (IMCCE), Kalliope’s profile at the occultation time was elongated (160 km ´ 220 km) and the shadow path width slightly increased (by about 25 km, in the Bessel plane), relative to the predictions, which used a 181 to 187 km mean diameter. Negative observations by LBA and ROY (just near the southern border of the predicted paths, inside the J. MANEK’s one, outside the S. PRESTON’s one) imply a small shift of the real path by at least half of these 25 km toward north (less than 0.1 path width).

JSZ and CTM were in double station.
amg : blinks probably due to clouds (J. Mc FARLAND observing a few meters away registered cloudy conditions).
Many observers were in the shadow path but didn’t observe any event. There must have been an important shift toward East (about one path width) but the lack of positive observation made it impossible to fix precisely.
FRP transmitted a negative observation by COF.

A possible satellite of (146) Lucina might have been observed during previous events : in 1982 (videorecording at the Meudon Obs. 1 m - telescope) and in 2001 (R. DUSSER reported a 1.9-s extinction when he observed visually a Lucina occultation on 2001.05.01). Its size could be ~15 km, and it can be anywhere as far apart as 2000 km from the main body.
Event published on KRT, NVI, PST web-sites.
RTH : videorecording.
IVY was situated on the centreline of the shadow path, since he registered a duration close to the max predicted one : 8.2 s. There must have been a small shift relative to NVI and PST predictions (0.6 path width toward SW), whereas KRT prediction was nearly exact.

MRX was just at the southern border. OKE was just at the northern border and registered an extinction about 15 s before the predicted time. OKE comment : “Star was very, very faint. I checked the tape from 20:50:00 to 20:52:00 UT several times. Star "maybe"disappeared for some seconds around 20:50:27, but I think star was lost in noise.”
JLX was well within the predicted shadow path. As the maximum predicted duration was 4.4 s, part of the observation (probably the emersion) is spurious. The best indication in favour of a real event is the good time agreement with PST prediction (~6 seconds early).

16 Reports have been sent by Tsutomu HAYAMIZU from JOIN (Japanese Occultation Information Network), about observations (one positive, one doubtful) of the occultation
of TYC 0272-00256-1 (mag. 9.7) by (253) Mathilde on 2004.04.09.
Predictions with finder charts and up-dated shadow path are regrouped (since September 2004) on the EAON web-site: http://astrosurf.com/eaon, maintained by Jean SCHWAENEN.

Received reports and results are

Saint-Etienne Observatory.
Please send the reports quickly, about positive as well as negative observations !
It is necessary to send a report even if there has been no occultation for your place (negative observation). These negative observations can sometimes be of as great interest as positive ones : they can be decisive to determine the shape (“shepherd observations”), refine the orbit of the asteroid or discover un unknown satellite ! Attention, there is no need to send a report if the weather conditions have prevented the event observation.
Please DON’T FORGET to use the IAU format for the date, YY.MM.DD.
