NEW METEOR SHOWERS RECOGNIZED
P. Jenniskens, Chair of IAU Commission 22's Task Group on Meteor Shower
Nomenclature, reports that, since the previous announcement (cf. CBET 1938),
the following 18 showers were added to the IAU Working List on Meteor Showers.
In the table below, the solar longitude, R.A., and Decl. are given in degrees
for equinox 2000.0; V_g is the geocentric velocity of the meteoroids at the
earth, but outside the earth's gravitational field. Other details for each
shower are given at the IAU Meteor Data Center's website (see the following
URL: http://www.ta3.sk/IAUC22DB/MDC2007/). The list is maintained by T.
Jopek, Poznan University.
