LEONID METEORS 2006
     P. Jenniskens, SETI Institute, reports, from observations at
Orgiva and Baza, Spain, that the earth encountered the two-revolution
dust trail of comet 55P/Tempel-Tuttle on 2006 Nov. 19d04h41m +/- 10m
UT (predicted time 19d04h50m +/- 15m; cf. CBET 710), with a FWHM of
54 +/- 15 min (predicted FWHM = 38 min) and peak rate of ZHR = 110 +/-
30 meteors/hr (predicted rate 50-200 per hour).  Larger meteoroids
than expected were present at this remote part of the dust trail.  The
observed Leonids had a magnitude distribution index of chi = 2.45 +/-
0.11 (predicted index 3.47 and up).  Observers at Orgiva were K.
Miskotte, M. Vandeputte, C. Johannink, J. van 't Leven, P. Bus, and P.
Jenniskens; at Baza, the observers were C. ter Kuile and R. Haas.
