UPDATE: May 25, 2014: It seems the shower was but a sprinkle of possibly 5-10 meteors per hour. As with some other events of this type, the media and social media hype far exceeds anything the true event could produce. But, it was a nice night for being out under the stars.
Astronomers are predicting a new meteor shower the morning of May 24th for North America. Comet 209P/LINEAR was discovered February 3, 2004 by Lincoln Near-Earth Asteroid Research (LINEAR). It has an orbital period of 5.1 years. At the farthest point from the Sun, it is nearly as far away as the orbit of Jupiter. At the nearest point, it is as far as the orbit of Earth from the Sun. Meteor counts of 100-400 per hour have been predicted by some astronomers. Some say there is a chance for up to 1000. No one knows for certain. This will be the first time Earth passes through the debris in the path of this comet.
I recorded this desktop simulation of the orbit of the comet intersecting the orbit of Earth to give a sense of perspective. The plane of the orbit of the comet is inclined about 22˚ to the plane of Earth’s orbit. We are expected to pass through the debris left on some of the previous passes of the comet in our neighborhood of space. No one knows exactly how much debris we will encounter. If we are lucky, it might be a large amount that could produce some beautiful meteor streaks from north to south.
Here are two frames from the video for you to get a better look. The first is an oblique view. The second is from directly above.
Viewed Above – Note the orbits of Earth and Jupiter
If you are fortunate to have clear skies where you live, look to the north for Polaris as depicted in this graphic from Space.com. The meteors are to radiate from the constellation Camelopardalis, the Giraffe, near Polaris. Note the location of the Ursa Major (Big Dipper) to the left and Cassiopeia to the right. This view is for the early morning hours of Saturday May 24th.
NASA released this excellent video summarizing the event and the best times to view it. I invite you to watch the 3 minute video. Let’s all hope for clear skies that morning. Set your clock. Chances are good you will see some meteors. It is is possible you will see something spectacular. Don’t risk missing it.
Here is one more special treat…the Moon occulted Saturn May 14 as seen from New South Wales in Australia. Thank for the video on Vimeo by Colin Legg.
Capture from 20 km north of Albury, NSW. I missed egress in February, so nice to get it this time around. Egress sequence centred around 10 pm Australian EST. The moon was higher for egress than ingress so seeing was better.
