General Description

This is a single observation of Delta Velorum at the exact time of its
 secondary total eclipse. The same kind of obsrvations were already recorded previously,
 outside of the eclipse. The only difficulty of this observation is its strict timing
 constraint, as the eclipse duration is only about 1h45 minutes.

Critical Observing Condition Constraints

This is a bright star and there is no critital observing condition.

Time-Critical Aspects

This observation must be done during the total eclipse of delta Vel Ab
 by delta Vel Aa. The time slot during which the star is eclipsed is between 2008-12-04UT06:26
 and 2008-12-04UT08:10. Preferentially, the observations should be executed between
 2008-12-04UT06:58 and 2008-12-04UT07:38 to ensure that the eclipse is really total.
