NEW METEOR SHOWER M2024-U1 IN LYRA
[Editor's note:  this text corrects that on CBET 5469 (m.p. designation)]
     D. Vida, University of Western Ontario, Canada; and D. Segon, Croatian
Meteor Network, report an outburst of meteors with a radiant in Lyra.
Seventeen meteors (magnitude range +2.5 to -1.25) were observed by the
Global Meteor Network low-light video cameras on 2024 Oct. 26-27 (cf. URL
https://globalmeteornetwork.org/data/).  The shower was independently observed
by cameras located in nine different countries.  The shower had a median
geocentric radiant with coordinates R.A. = 288.87 deg, Decl. = +37.01 deg,
within a circle having a standard deviation of +/- 0.55 deg (equinox J2000.0).
The median sun-centered ecliptic coordinates were L-L0 = 85.98 deg, beta =
+58.52 deg.  The geocentric velocity was very low at 13.1 +/- 0.3 km/s.  The
orbital elements are those of a Jupiter-family comet (Tisserand parameter 2.9
+/- 0.1):  q = 0.99382 +/- 0.00004 AU, e = 0.65 +/- 0.01, i =  16.86 +/- 0.48
deg, Peri. = 179.9 +/- 0.7 deg, Node = 213.67 +/- 0.16 deg (equinox J2000.0).
All meteors appeared in the solar-longitude interval 213.42-213.94 degrees,
with a peak around 213.55 deg.  A parent-body search suggests possible parent
bodies might be 2014 UR_34 (with Southworth and Hawkins D criterion of 0.07)
or comet 185P/Petriew (Southworth and Hawkins D criterion of 0.1).  The new
shower received the working designation M2024-U1 from the IAU Meteor Data
Center.
