February Hydrids Meteor Shower Outburst

February Hydrids Meteor Shower Outburst

Screen capture of the outburst as seen from CAMS

Peter Jenniskens reports that the global Cameras for Allsky Meteor Surveillance (CAMS) low-light video-camera networks detected an outburst of February Hydrids this year (cf. website URL http://cams.seti.org/FDL/ for dates of 2023 Feb. 11-17). The shower was previously in outburst in 2013 (when 3 meteors were triangulated) and in 2018, when the shower was first recognized from twelve triangulated orbits. The shower is nearly absent in CAMS data in other years.  The episodic returns and measured semi-major axis are consistent with a 4.7-year periodicity from dust trapped in the 5:2 mean motion resonance with Jupiter.  Based on the shape of the orbit, this shower is caused by an unidentified Jupiter-family comet.

JWST: NASA’s Amazing Next Generation Observatory


JWST eBook preview

The James Webb Space Telescope (JWST) has been called Hubble’s successor, and in terms of how it could revolutionize astronomy, perhaps it will earn that title. But JWST’s true lineage lies in the invisible realm of infrared astronomy, a type of light that can unlock the secrets of star birth, the chemistry of exoplanets, and the dawn of the age of galaxies. Meet JWST’s predecessors, get to know the beauty of the infrared sky, and see how JWST’s amazing design will change the way we see, and comprehend, our universe.
