2002 (January to February) Observations

Usually negative, excepted when otherwise specified. ‘mp’ stands for the minor planet, ‘*’ for the star. All times are in UTC.

Differential astrometry of mp and * from Sabadell and pdm yields conflicting results.

Anyway, PSY is well away the shadow path deduced from the two sets of astrometric measurements (resp. 692 or 1036 km, i.e. 9 to 13 times the diameter of Arctica). Photometric analysis of the original CCD file of PSY gives only 0.4 magnitude for the event depth. Any real occultation should have an amplitude of 3.2 magnitudes. Thus if this brief occultation was a real one, it was only very partial or by a secondary body very much brighter than the main one. In the two cases, such a distant satellite would have been detected visually for a long time. Not easy to explain, this event had chances to be spurious : the tiny break in the trail could sum up just to a fortuitous succession of 6 low counts in consecutive pixels, a wrong consequence of the weak star/sky ratio (about 0.07) in the frame.

Astrometric data closely confirm the last update by S.Preston. TVH observation has been interrupted at closest approach by thin clouds.
