Chords can be fitted with a 180 × 150 km elliptic profile. Positive observations show the prediction to be exact, at least concerning the position of the centreline. As the short axis was nearly parallel to asteroid motion, the path width was significantly larger than the predicted one, calculated with a 163 km mean diameter.

Note that a similar profile 190 × 155 km has been deduced from 6 chords obtained during the 1994/01/08 event involving HIP 11895 observed from Australia. (from WINOCCULT database)

ELL : observation performed through clouds; only the second disappearance seems to be a true occultation, nothing can be said about the events at the beginning and end - 'graze' phenomena or cloud ?

ELL was just at the southern border of the predicted path but surprisingly observed an event with duration significantly large relative to the max predicted one ( 12.1 s). No conclusion can be drawn : path might have been slightly shifted (about one half of its width) toward SW, but an elongated shape and/or a larger than supposed (42 km) size cannot be excluded.

Observations (BDM and BLI positive and PSY and RAI negative ones) lead to a shift of the path toward S, by one of its width

BLI : Faint flash at 00:32:21.58, taking place exactly at mid-occultation. This could be due to a binary asteroid (two bodies nearly in contact) but in the present case, more likely to a Poisson effect (diffraction of the star light by the asteroid profile, visible only in the axis star-asteroid).

BDM, FRP, RNC : CCD drift scan; FAP : videorecording

FAU : an unexplained ~25s shift must be applied to fit with other observers.

FRP : with LVY; RNC : with F. KUGEL

Chords can be fitted with an elongated profile : 131 × 88 km, with long axis nearly perpendicular to asteroid motion (to be compared with the 108 km mean diameter used for calculation ). A certain scatter may occur, but the shape of the asteroid may be irregular as well. At least concerning the position of the centreline, the prediction was exact since FRP was nearly on the predicted centreline, and his chord is effectively the one of the profile barycentre.

Note that PSY was outside the predicted track but observed an event because of the elongated shape of (40) Harmonia.

2007/12/15 : ( 441 ) Bathilde / TYC 4925-01297-1 GAR

GAR was in the predicted shadow path. His negative observation shows the real one has been shifted but the lack of positive observation lets its position remaining unknown.

ALY, MID, OKE, RTH, WSG : videorecording; MVZ OKE RTH trt WSG

AUD : CCD drift-scan;

FIL : with O. DECHAMBRE, CCD drift-scan ; JNK : no occultation longer than 0.5 s.

JLX, ALY, FIL were in or at immediate vicinity of the predicted path. Incertitude was large for this 27 km asteroid (one s limit was at about five path widths from predicted centreline).

2007/12/18 : ( 219 ) Thusnelda / HIP 38140 CRB

Negative observations from Catania (N 37 33 23, E 15 04 53) and Palermo.

2007/12/19 : ( 5074 ) Goetzoertel / TYC 2409-00519-1 AUD RAI

AUD : CCD drift-scan Incertitude was large for this 15 km asteroid asteroid (one s limit was at about ten path widths from predicted centreline)

2007/12/23 : ( 409 ) Aspasia / TYC 0757-02395-1 JLX

JLX videorecorded the appulse from a site located at N 46 31 08 E 01 50 20 ); (409) Aspasia passed 0.45 ± 0.08" South (560 ± 100 km) from the faint target star, at 22:58:31 UT ± 8s. It results that the occultation path seemed in reasonable agreement with the prediction by Steve PRESTON although the closest approach happened more than one minute earlier than predicted.

2007/12/24 : ( 198 ) Ampella / TYC 1783-00860-1

Received reports and results are summarized on http://www.euraster.net , a web page maintained by Eric FRAPPA from Saint-Etienne Observatory.

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"), refine the orbit of the asteroid or discover un unknown satellite !  

Please DON’T FORGET to use the IAU format YYMMDD for the date of your reports. Clear skies for all.
