DAYTIME CRATERID METEORS
     Peter Brown, University of Western Ontario, reports (via P. Jenniskens)
from observations with the Canadian Meteor Orbit Radar that the Daytime
Craterid meteors (DCR; IAU meteor shower number 426) are in outburst.  Based
on similar outbursts in 2003 and 2008, it is expected that this periodic
shower will show strong activity over the next four days and peak on Sept. 1
(around solar longitude 158 deg).  The radiant of the shower at the peak will
be at R.A. = 169 deg, Decl. = -15 deg (equinox 2000.0).  The apparent
velocity is 20 km/s, and the geocentric velocity is 18 km/s.  This location
of the radiant is very near the sun, which means that the shower can be seen
visually only in the hour after sunset, best from locations at southern
latitudes.  It is possible to follow the "DCR" activity at the following
