NEW METEOR SHOWER M2024-U1 IN LYRA
     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 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 in nine countries across the
globe.  The shower had a median geocentric radiant with coordinates R.A.
= 288.87 deg, Decl. = +37.01 deg, within a circle with 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_36 (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.
