PERSEID STORM IN EASTERN EUROPE...

Data from Hungarian meteor observers and several radio amateurs in the USA
and Finland have revealed the strong possiblity that the expected strong 
return of the Perseids in 1992 *did* take place. The observations in question
suggest 19-20 UT on Aug 11/12 as the time the outburst occurred. This is 
several hours earlier than predicted since the predicition was based on
the assumption that the activity which took place over Japan in 1991 would
recur again at the same position in the Earth's orbit, namely at 138.86 
(1950.0). As was pointed out by Marsden if the the shower recurred at 
precisely the node of P/Swift-Tuttle the storm would occur several
hours before the 22-23 UT Aug 11/12 shortly after 19 UT, as seems to have
happened. This is **very** strong evidence to suggest that P/Swift-Tuttle is
very nearby and searches for the comet should certainly go into high gear.
This outburst occurred at 138.74 (1950.0) and if it recurs again within
a few tenths of degrees of this position then we can expect a nice meteor
shower in 1993 on Aug 12 at about 1-2 UT. This means North America might
catch some of the activity early in the evening and the moon will be only
4 days from new!! 
Since many details are still missing it is *imperative* that observers either
radio or visual who have data in the interval 18-20 UT report it as soon as
possible so a complete picture of what happened can be constructed.
Further details can be found on IAUC 5586.
