CAMELOPARDALID METEORS 2014
     P. Brown, University of Western Ontario, reports enhanced activity
associated with the Camelopardalid meteor shower (cf. CBET 3869) based on data
from the Canadian Meteor Orbit Radar.  Shower activity was noticeable during
0h-11h UT on May 24, with a peak (based on numbers of orbits detected) between
7h30m and 8h00m UT.  Using a wavelet-based measurement procedure (cf. Brown
2010, Icarus 207, 66), the mean shower radiant is found to be around R.A. =
124 deg, Decl. = +80 deg (equinox 2000.0), with an estimated (deceleration-
corrected) initial velocity of 21 km/s, based on 92 measured Camelopardalid
radar echoes.  The radiant position and timing is very near the location of
earlier predictions (Ye and Wiegert 2014, MNRAS 437, 3283; CBET 3869),
suggesting that debris from comet 209P/LINEAR encountered the earth much as
predicted.  The shower radar echoes were confined to faint meteors (equivalent
visual magnitude 6-7), consistent with the debris trail populated mainly by
particles of milligram mass and smaller.
