GAMMA DRACONIDS METEORS 2025
     P. Jenniskens, SETI Institute and NASA Ames Research Center; and C.
Johannink and M. Breukers, Dutch Meteor Society, report that the CAMS/BeNeLux
low-light video camera network triangulated nine gamma-Draconid meteors
between 2025 Apr. 4d21h and 5d04h UTC (cf. URL http://cams.seti.org/FDL/ for
the date of 2025 Apr. 5).  Only one meteor of this shower was detected on this
date by all CAMS networks combined in 2024.  The shower had a compact
geocentric radiant at R.A. = 275.6 deg, Decl. = +53.8 deg, and geocentric
velocity 36.5 km/s during solar longitude 15.01-15.28 deg (equinox J2000.0),
with the following corresponding Mellish-type or long-period-comet-type median
orbital elements (N = 9 orbits):  q = 1.0003 +/- 0.0003 AU, e = 0.937 +/-
0.120, i = 59.1 +/- 1.7 deg, Peri. = 179.0 +/- 1.3 deg, Node = 15.189 +/-
0.096 deg, in good agreement with those of the annual shower (cf. Jenniskens
2023, *Atlas of Earth's Meteor Showers*, p. 773).
