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.

ELL : videorecording; the site is just within the predicted track, close to the northern edge but no occultation was evident on playback.  However, the predicted magnitude drop was only 0.29 so the tape would require further analysis to be sure.

 

2005.01.15 : (654) Zelinda / TYC 1194-01098 -1                      JLX        NEL

JLX : CCD imaging at Pic-du-Midi (N 42 56 10.8 E 00 08 32.2 +2880 m). Event  predicted as central at 17:58.8 UT, at this location both by Winoccult1 with actualized data and by M. Kretlow. Approximate miss distance, from only 4 CCD images: ~ 0.2" S (or 300 km) at 17:58.7 UT – what means that the real occultation path crossed over north of Spain.

                [asteroid 0".225 ± 0".015  (2 sd) N of star at 18:52:46.5 UT ± 3 s., from 95 CCD images]

So according to these measurements, the Pic-du-Midi was about 380 km South (in the Bessel plane) from the centreline, a little more than what can be deduced (275 km) from the positive observations (BAO was nearly on the centreline, as the maximum predicted duration is 5.3 s). The path has been shifted toward north by about its width, relative to the Winoccult[1] prediction.

JLX comment :  “Predicted apparent mean radius of (690) Wratislavia : 0".037,  maximum predicted duration for assumed diameter 145 km : 6.8 s. From the above astrometry, my chord (142 ±2 km) was a bit southerly relative to the asteroid centre, but not so far as  I have measured.  As actually I took the astrometric images far from culmination, between the altitudes 48 deg. and 19 deg., it probably resulted  some systematic declination excess, maybe by 0".04-0".05 (?), because of the differential colour between the grey asteroid   (C-type, B-V= +0.66) and the red star (B-V= +1.5)”.

The path has been shifted by about half of its width, toward south, relative to the Winoccult1 prediction.

As PCI was the only observer and registered an event duration significantly shorter than the maximum predicted one (4.2 s), one cannot say if he was on the northern or southern side of the shadow path. At least, the path has been shifted by about 0.75 path width toward north, relative to S. Preston prediction.

Several observers were in the predicted shadow path but reported no occultation. So the path has been shifted but the lack of positive observations lets its real location remaining unknown.

PCI : CCD drift-scan. A 1.6 s long light drop from 18:03:49.7 to 51.3 (50 km long chord) needs to be confirmed.

As the appulse time was predicted at approx. 18:45:30 for this location, situated far (about 1.5 path width) toward north of the predicted path, obviously this light drop doesn’t concern the Hertha event.

Central event was predicted at approx. 23:16:30 (M. Kretlow), 23:16:45 (S. Preston) for this location, situated on the northern limit of S. Preston’s predicted path. As the maximum duration was 4.8 s, the real path must have been shifted by about half of its width toward north relative to the S. Preston’s prediction (by about three path widths relative to M. Kretlow’s one).

Positive observations show a half width shift of the shadow path toward south. This shift made AZT just miss the event. The chords are scattered but can be fitted with a 150 km -mean diameter circle, in agreement with the assumed one : 160 km.

The negative observations of ELL, JLX, FRP and LVY (all of them in the predicted path, the three last after a long special trip) and the positive observation of SPS and its duration, close to the maximum value ( 9.9 s ), reveal a shift of about four path widths toward NE, relative to the S. Preston updated prediction. JHP just missed the southern limb of the asteroid.

Received reports and results are summarized on www.euraster.net, a web page maintained by Eric FRAPPA from

Predictions with finder charts and up-dated shadow path are regrouped on the EAON web-site: http://astrosurf.com/eaon, maintained by Jean SCHWAENEN.

 

It is necessary to send a report even if there has been no occultation from 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” : see the case of AZT for the Zelia event or of JHP for the Bronislawa one, in this info), refine the orbit of the asteroid or discover un unknown satellite !  

Please DON’T FORGET to use the IAU format for the date, YYMMDD.
