Hopefully we'll be able to spot the 29th January asteroid

Hubble will be covering the 2007 WD5/Mars close approach. From the schedule:
11497 A6C Noll Observations of Mars and 2007 WD5 2008.030 10:54:00 11:05:00 1149705 Noll 05-001 MARS WFPC2 IMAGE PC1-FIX F410M 1.20 05 01 02 2008.030 10:54:00 11:05:00 1149705 Noll 05-002 MARS WFPC2 IMAGE PC1-FIX F502N 1.80 05 01 03 2008.030 10:54:00 11:05:00 1149705 Noll 05-003 MARS WFPC2 IMAGE PC1 F673N 0.40 05 01 04 By the fact that they are only using three filters (approximately RGB) and Kieth Noll who sets up Hubble Heritage observations, this is likely simply being done for the coolness factor. -------------------- |

QUOTE (tedstryk @ Jan 25 2008, 09:09 PM)  Hubble will be covering the 2007 WD5/Mars close approach. From the schedule: FWIW, the Hubble observations have not yet made their way into the major asteroid tracking sites. Both JPL and NEODys are reporting their most recent observations as 2008-01-09. Assuming they can do good astrometry from a moving telescope, observations so close to the asteroid's pass by Mars should refine the subsequent trajectory.11497 A6C Noll Observations of Mars and 2007 WD5 2008.030 10:54:00 11:05:00 1149705 Noll 05-001 MARS WFPC2 IMAGE PC1-FIX F410M 1.20 05 01 02 2008.030 10:54:00 11:05:00 1149705 Noll 05-002 MARS WFPC2 IMAGE PC1-FIX F502N 1.80 05 01 03 2008.030 10:54:00 11:05:00 1149705 Noll 05-003 MARS WFPC2 IMAGE PC1 F673N 0.40 05 01 04 Steve M |
