Jan 1/2 Meteors and Tonight’s Quadrantids
January 2, 2014 1 Comment
Tonight brings the peak of the best meteor shower you have probably never seen. The best showers of the year are almost always August’s Perseids and December’s Geminids. Number 3 and 4 are usually October’s Orionids or tonight’s shower, the Quadrantids.
The reason I say the Quads are probably the best shower you’ve never seen is two-fold. First as a northern shower, they take place in the dead of winter and only a few days after New Year’s. If the exhaustion from the Holiday’s season doesn’t keep most people inside then the cold definitely will. Also unlike most showers which have broad peaks which last a few days, the peak of the Quads is very narrow. Even if you are observing on the peak night, you can miss much of the show if you are off the peak by only 12 hours.
The International Meteor Organization predicts this year’s Quads peak to take place at ~19:30 UT on the 3rd which suggests the best viewing will be in Asia. But… predicting the peak time for this shower is always difficult so pretty much anywhere on Earth may see the best. The only way to know is to get out and look.
Bob Lunsford has posted an excellent guide to observing the Quads at the American Meteor Society (AMS) website. Please check it and the AMS (of which I am their Secretary) out.
For many years, astronomers were uncertain as to which comet caused the Quadrantids. No known comets was visible on a similar orbit even though the narrowness and strength of the meteor stream suggested it was created recently. We now know that the asteroid (196256) 2003 EH1 is the likely parent body of the Quads. Even though today it appears as nothing more than an asteroid it was a comet in the past and a rather bright one when seen in 1490. Earlier this year I observed 2003 EH1 with the Vatican Obs/Univ. of Arizona VATT 1.8-m as seen in the image below.
[I forgot to add that yesterday’s Earth impacting asteroid, 2014 AA, is not related to the Quadrantid meteor shower. The asteroid and the meteors have very different orbits and the fact that they both intersected the Earth on the same day (or two) is not only a coincidence but shows just how crowded space is with debris.]
Last night was another clear night in Tucson. Though 28 meteors were detected, only 2 were possible Quads. Tonight should see a huge increase in Quadrantid meteors.
