3-SAGITTARIIDS METEOR OUTBURST 2025
     P. Jenniskens, SETI Institute and NASA Ames Research Center; T. Cooper,
Cameras for Allsky Meteor Surveillance (CAMS) project, South Africa; N.
Moskovitz and S. Hemmelgarn, Lowell Observatory CAMS; J. Scott and W. J.
Baggaley, CAMS, New Zealand; and M. Odeh, United Arab Emirates Astronomical
Camera Network, report a meteor outburst of 3-Sagittariids (IAU shower 1132)
starting on June 11 and ongoing on June 23, when 165 shower meteors were
detected (see website URL http://cams.seti.org/FDL/ for dates of 2025 June
20-23).  During the solar longitude interval 87.9-91.2 deg, the shower
radiated from a compact geocentric radiant (with standard errors for the
median) centered at R.A. = 270.16 +/- 0.08, Decl. = -29.00 +/- 0.05 with
geocentric velocity 24.72 +/- 0.12 km/s (N = 112).  The corresponding
sun-centered radiant has longitude = 180.46 +/- 0.06 deg, latitude = -5.56
+/- 0.05 deg.  The median orbital elements are those of a Jupiter-family comet
with a = 2.97 AU, q = 0.543 +/- 0.001 AU, e = 0.816 +/- 0.004, i = 4.73 +/-
0.05 deg, Peri. = 91.5 +/- 0.1 deg, Node = 269.92 +/- 0.08 (equinox J2000.0).
Past CAMS data only show a weak detection, and this shower was not included in
the Atlas of Earth's Meteor Showers (Jenniskens 2023).
