X-37B SIGHTINGS: Amateur satellite watchers have spotted a US Air Force space plane similar in appearance to NASA's space shuttle circling Earth in a heretofore secret orbit. Known as the "X-37B," it can be seen in the night sky shining about as brightly as the stars of the Big Dipper. Flyby predictions and more information may be found at http://spaceweather.com .

AURORA WATCH: A magnetic filament on the sun erupted yesterday (May 24th), and the blast hurled a coronal mass ejection in the general direction of Earth. High-latitude sky watchers should be alert for auroras around May 27th when the advancing cloud is likely to deal a glancing blow to our planet's magnetic field.
