Re: (meteorobs) Meteor Hunt of November 4/5, 2002!



Hi Mark and meteor observers,

Many thanks for the Taurid report. It looks very fine,
and it's just some thoughts I'd like to mention.

When computed from the path length and duration, the
angular velocities are all very plausible. The Taurids
are generally slow

This leads to 10, 7, 3, 6, 10+, and 8 degrees/sec. All these
velocities are relatively slow, but since the observation
was done in the early evening, also the sporadics are expected
to be slow in general. Looks consistent. You might try to
estimate deg/sec directly without the detour via path length
and duration.

The SKY OBSCURED may be misleading. It sounds like an observer
should have the entire sky as a field of view. The typical
field, however, in which 98% of the meteors are seen is slightly
larger than 100 degrees in diameter. Only obscuration of this 
field should be noted. Could you tell whether you refer to the
entire sky or a field of view with these 20%?

Best wishes,
Rainer
