This prediction update has been computed by Stephen Kerr based on astrometry from Ron Stone of the US Naval Observatory - Flagstaff Station. The Tycho-1 position of the target star has been used.

Summary:

This update places the new path around 1.5 of a path width to the north-east and about 20 seconds later than given by Goffin. The path now crosses New Caledonia (9:55 UT) and southern Papua New Guinea (9:59 UT).

• Date and approx. UT time of event: June 16, 2000 @ 9:51 UT
• Magnitude of target star: 10.38
• Magnitude drop [mag]: 2.0
• Estimated maximum duration [s]: 15.9
• Path description: See above.
• Goffin's original chart reference: A00_0613

• Approximate width [km]: 169
• Map: See below

• Name: TYC 6779 780 = PPM 264931 = SAO 183978
• Constellation: Scorpius
• J2000 position [h,m,s; ^o,',"]: 15h 58m 12.707s; -23^o 28' 36.51"
• Position source: Tycho 1
• V mag [mag]: 10.38
• Spectral Type: G5
• Remarks:
• The target star is in western Scorpius. It lies 1 degree south-west of delta Scorpii (magnitude = 2.3). The magnitude 6.8 star HIP 78183 = V928 Sco lies only 6' south-west of the target star.

• Number, name: (241) Germania
• Approx. diameter [km]: 169
• Source of used astrometry: US Naval Observatory - Flagstaff Station (Ron Stone)
• Number of used observations: 9
• Number of rejected observations: 0
• Time covered by the observations: 2000 05 23 - 2000 06 09

• UT date and time of least geocentric approach: 2000 June 16, 9:51.814 UT
• Approx. V mag of minor planet at event [mag]: 12.16
• Geocentric parallax of minor planet ["]: 3.35
• Magnitude drop [mag]: 2.0
• Estimated maximum duration [s]: 15.9
• Apparent motion of minor planet ["/h]: 25.17
• Angular distance to moon, phase of moon [deg,%]: 19, 100%
• Update computed by: Stephen Kerr - DOS Occult 4.2

IMPORTANT NOTE!

Astrometric updates such as these should not be taken as definitive, but rather only as an indication of where the true track may lie relative to the original predicted track. Observers must bear in mind that later astrometry, in which the target star is measured in the same field as the asteroid, may still reveal substantial changes to the predicted track and time of the event. For this reason it is most important that observers far from the predicted track still monitor the event.
