View the updated prediction.

Observers:
  1    S. Buda, St Kilda East, Australia    
  2(M) D. Herald, Woden, ACT, Australia     
  3(M) D. Gault, Hawkesbury Hts, Australia  

(M) = miss.

Tamara occultation - 2005 April 13

The circle represents the predicted 93 km diameter of Tamara.

Discussion:

Stefan's 1.6 second occultation seen from St Kilda (Melbourne) indicates that he was near either the northern or southern limit of the track. No other observations were reported from Victoria, although the path also passed a little south of ACT where David Herald recorded a miss, and across southern NSW where Dave Gault also recorded a miss.
