Strong Metor Shower is Expected Tonight

The annual Perseid meteor shower is expected to put on a good show this week for those willing to get up in the wee hours of the morning and wait patiently for the shooting stars, and Bonaire, with its lack of light pollution, should provide an excellent viewing platform.

In the northern hemisphere, the best time to watch will be between midnight to 5 a.m. on Wednesday, Aug. 12, but late Tuesday night and also Wednesday night could prove fruitful, weather permitting.  The Perseids are always reliable, and sometimes rather spectacular. The only things that puts a damper on the August show are bad weather or bright moonlight. Unfortunately this week, as the Perseids reach their peak tonight and tomorrow, the moon will be high in the sky, outshining the fainter meteors.

The Perseids are bits of debris from Comet Swift-Tuttle, which has laid down several streams of debris, each in a slightly different location, over the centuries as it orbits the sun. Every August, Earth passes through these debris streams, which spread out over time.

Low numbers of Perseids, including some bright fireballs, have already been reported as Earth began entering the stream in late July. Seasoned observers have counted up to 25 per hour already, or nearly one every two minutes.  Most meteors are no bigger than a pea. They vaporize as they enter Earth’s atmosphere, creating bright streaks across the sky.

Astronomers expect up to 200 meteors per hour in short bursts of up to 15 minutes or so. But many of the fainter meteors will simply not be visible due to moonlight, and rates will go down even more for those in urban areas. More likely a typical observer under reasonably dark skies might hope to see a meteor every couple minutes when the bursts come, and fewer during lulls.

The best time to watch is between midnight and dawn Wednesday. Forecasters say the best stretch could come between 4 a.m. and 5 a.m. AST.  Some Perseids might be visible late Tuesday night, and Wednesday night into Thursday morning could prove worthwhile, too.

The best location is away from Kralendijk, ideally where there are no lights.  Attempt to find a structure or tree to block the moon.  Then scan as much of the sky as possible. The meteors can appear anywhere, heading in any direction. If you trace their paths backward, they’ll all point to the constellation Perseus.  Seasoned sky-watchers advise using a blanket or lounge chair for comfort, so you can lie back and look up for long periods. Allow at least 15 minutes for your eyes to fully adjust to the darkness. Then expect meteors to be sporadic: You might see two in a row, or several minutes could go by between shooting stars.
