PERSEID PEAK - ADDITIONAL MAXIMA?
By Alastair McBeath

Late predictions of a clutch of possible additional Perseid maximum 
timings were issued by the IAU on August 3, based on independent 
work by Peter Jenniskens, Esko Lyytinen, I. Sato and Jeremie 
Vaubaillon. These included peaks around August 12, 22h55m UT (but 
not all researchers agreed on this timing; others suggested August 12, 
22h42m UT or August 13, 00h27m UT; ZHRs probably just a weak 
addition to the existing rates, so perhaps not sensibly identifiable), 
August 13, ~04h UT (ZHRs unknown, suggested as due to a young 
stream filament) and August 13, ~10h UT (ZHRs 80 +/- 20). As 
these straddle the existing International Meteor Organization predictions 
for around 05:00-07:30 UT on August 13, already given in ENB 225 
and on the SPA website, August 12-13 remains the key night for 
British watchers, but the importance of continuing to observe for as 
long as possible overnight then is emphasized, to get the best idea of 
when - or if - any of these predictions prove accurate.
