Space Station Flares

SPACE STATION FLARES: Lately, a growing number of observers are reporting intense "flares" coming from the International Space Station (ISS). During some nighttime flybys, the luminosity of the space station surges 10-fold or more. Some people have witnessed flares of magnitude -8 or twenty-five times brighter than Venus. A movie featured on today's edition of http://spaceweather.com shows what is happening: sunlight glints from the station's recently expanded solar arrays in a shadow-casting flash. Currently, the flares are unpredictable. You watch a flyby not knowing if one will happen or how bright it might be. That's what makes the hunt for "ISS flares" so much fun.Sky watchers in North America should be alert for flares this week. The ISS is making a series of evening passes over many US and Canadian towns and cities. Flyby times are available from the Simple Satellite Tracker: http://spaceweather.com/flybys

Visible Satellite Crash Debris

SATELLITE DEBRIS: On Feb. 10, 2009, Iridium 33 crashed into Cosmos 2251 and the two satellites were shattered. Since then, US Strategic Command has catalogued nearly a thousand pieces of debris. Today's edition of http://spaceweather.com presents 3D maps showing where the fragments are located on the three-month anniversary of the unprecedented collision. One large piece of Iridium 33 wreckage is visible to the naked eye as it tumbles through the night sky flashing every 4.7 seconds.

Forecasters expect the shower to peak on Wednesday, May 6th, with as many as 85 meteors per hour over the southern hemisphere. Rates in the northern hemisphere will be less, 20 to 30 per hour.
