Electronic Telegram No. 2758 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION CBAT Director: Daniel W. E. Green; Hoffman Lab 209; Harvard University; 20 Oxford St.; Cambridge, MA 02138; U.S.A. e-mail: cbatiau@eps.harvard.edu (alternate cbat@iau.org) URL http://www.cbat.eps.harvard.edu/index.html Prepared using the Tamkin Foundation Computer Network 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.
