DRACONID METEORS 2025
     P. Jenniskens, SETI Institute and NASA Ames Research Center; and M. Odeh,
International Astronomical Center, Abu Dhabi, United Arab Emirates, report a
weak detection of a predicted Draconid meteor shower outburst by low-light
video cameras on Oct. 8.  The outburst was predicted by Egal et al. (2025,
MNRAS Letters, 2025 Oct. 3) as an encounter with primarily the 2012 return
dust ejecta of parent comet 21P/Giacobini-Zinner, with a possible minor
contribution from the comet's return in 2005.  The meteors were predicted to
be primarily faint (magnitude 4 and fainter) and detectable by radar, with
peak activity between 15h and 16h UTC on 2025 Oct. 8.  The video cameras of
the UAE Astronomical Camera Network triangulated Draconid meteors at 15h13m,
15h18m, 15h26m, 15h33m, 16h19m, and 16h44m UTC on Oct. 8, and no meteors
later that night (observing interval Oct. 8d15h07m-9d01h33m UTC).  These
meteors were only slightly brighter than fourth magnitude:  respectively,
3.2, 1.5, 1.9, 2.2, 1.4, and +2.2, in good agreement with the predictions
(cf. website URL http://cams.seti.org/FDL/ for the dates of Oct. 8 and 9).
Jenniskens adds that a report was received from J. Trigo-Rodriguez (Spanish
Meteor Network) stating that the outburst was detected by the Riudellots de
la Selva-Girona forward meteor scatter station of J. Figueras, and a report
by I. Yrjola confirms the detection by forward meteor scatter from a station
at Kuusankoski, Finland.
