Tau Herculids Meteor Shower (11mm Ra) with Labels.jpg
The rare Tau Herculids meteor shower predicted for May 30/31, 2022 as a possible meteor storm, but instead produced a modest "normal" meteor shower. The meteors appeared yellowish (as in the bright meteor) and were slow-moving, and often had a sparkling effect as they moved, again as per the irregular brightness of the bright meteor streak. The meteors were from remnants of the Comet 73P/Schawassmann-Wachmann 3 which broke apart in 1995.
This is a blend of exposures taken over nearly 90 minutes from 11:23 pm MDT to 12:47 am MDT, capturing 15 meteors, including a very bright one, the best of the night, which left an orange ionization "smoke" trail expanding away from the meteor over the next few minutes. The blend includess at least three non-shower "sporadic" meteors, including one very bright one shooting toward the horizon at left in Scorpius.
This shows the radiant point of the Tau Herculids, actually located in Boötes above the bright star Arcturus above centre. The field of view spans the sky from Leo, setting at far right, to Lyra and the summer Milky Way rising at far left. The Coma Berenices star cluster is below the bright meteor. Corona Borealis and Hercules are left of Arcturus, while bright Vega in Lyra is at upper left. Spica in Virgo is low in the southwest at bottom right. Scorpius and Antares are low in the southeast rising on the horizon.
This is a blend of 18 exposures for the meteors and smoke trails, stacked onto the sky background taken just before the very bright meteor occured earlier in the night when the sky was still blue from lingering twilight.
All were with the Canon Ra for 15 seconds each but at ISOs from 1600 to 6400, increased through the night as the sky darkened, and with the 11mm TTArtisan full-frame fish-eye lens wide open at f/2.8. The camera was on a Star Adventurer tracking mount to keep the stars stationary over the sequence to aid in aligning and stacking the images, so the meteors appear in their correct positions r
