Dec 22nd 1999: Campaign for Photometric observation of (2953) Vysheslavia in January 2000
Astrometric observations of 1992 RF5, 1998 DX1 and 1989 TT3 during the year 2000
Jun 7th 2000: Another 7 asteroids in the surroundings of the 5:2 resonance, two of them, namely (6814) and 2000 GQ6, are located inside the chaotic zone.
Apr 20th 2000: Slides presented at the seminar of Institute of Astronomy MFF UK (Apr 19th 2000) [semau_2953.ps.gz, 1.4 MB]
Apr 20th 2000: Addons: Photometry of (2953) Vysheslavia done by L. Sarounova in Jan 2000. Analysis of "jumps" in runs 2953-cp0bsf, 2953-cp2bsf.
Next conferences we wish to attend are US - European Workshop on Celestial Mechanics (Poznan, Jul 3-7 2000) and NATO ASI - The Restless Universe (Blair Atholl, Jul 23-Aug 5 2000).
Oct 20th 1999: We presented our preliminary results on AAS DPS 31th annual meeting (Padova, Oct 10-15). Look for the slides in the download section.
