We have already taken several exposures of these asteroids and weather permitting, we will take CCD exposures at our observatory at particular times (e.g. 0h00 and 1:00 UT). Submitted by: Astronomische Arbeitsgemeinschaft Osnabrueck Positions: 84 Klio: 19. 1h UT: RA 02h 05m 14s decl. +31d 11' 39" (2000) 20. 1h UT: 02 04 29 +31 04 20 990 Yerkes: 19. 1h UT: 02 39 05 +29 13 19 20. 1h UT: 02 38 09 +29 10 02 584 Semiramis: 19. 1h UT: 02 34 49 +32 48 33 20. 1h UT: 02 34 05 +32 36 01 Magnitudes: 84: 11.8, 990: 14.3, 584: 10.6mag List of exposures: several short (30s) exposures at larger time intervals (1h) preferrably with R filter Rationale: In collaboration with the Koblenz group we try to determine the absolute dimensions of the solar system. More details are given in the collaborative project "distance to the sun". We have already got some experience in astrometric work and we have taken exposures to determine the orbit of the asteroids (see our web-page www.physik.uni-osnabrueck.de/students/ahaenel). Comments: Observations from the two observatories should be taken as simultaneous as possible. But as this might not be possible, several exposures at time intervals should be taken to allow interpolation. Suggested Telscopes: La Silla Dutch or La Palma to have a large enough baseline.
