> SEPTEMBER PERSEID METEORS 2008
>     P. Jenniskens, SETI Institute, reports that the September Perseid
> shower
> had an outburst of mostly bright (magnitude +4 to -8) meteors on Sept.
> 9d08h20m +/- 20m UT over a period of four hours.  J. Brower (Kelowna, BC,
> Canada) recorded eleven September Perseids of magnitude +1 and brighter
> with
> a wide-field, low-light-level video camera between 7h26m and 9h21m UT (and
> only two other meteors in the period 3h00m-13h30m).  P. Martsching
> (Ames, IA,
> U.S.A.) visually observed no unusual activity from 5h to 6h UT -- but then
> increasing rates, many meteors having negative magnitude (to -8) and nearly
> all leaving a brief train.  The outburst is confirmed by several "Radio
> Forward Meteor Scatter" observers, including E. Lyytinen (Helsinki,
> Finland),
> who observed increased rates from 7h18m to 10h05m, and D. Entwistle
> (Goosnargh, UK).  W. J. Cooke, Meteor Environments Office, Marshall
> Spaceflight Center, NASA, reports -- from single-station, all-sky video
> observations -- a significant outburst of bright meteors between Sept.
> 9d06h20m and 10h30m UT.  In total, some 25 meteors of apparent magnitude
> greater than -2 were detected from a single radiant during this 4-hr
> interval.
> An approximate apparent radiant is found to be at R.A. = 49.5 deg, Decl. =
> +43.0 deg -- close to the radiant of the September Perseid shower at R.A. =
> 50 deg., Decl. = +39 deg, nominally thought to peak during Sept. 10-12
> (Jenniskens 2006, Meteor Showers and Their Parent Comets, Cambridge Univ.
> Press).  No previous outbursts of this shower are known.
