SPACE PLANE FLARES: The US Air Force X-37B space plane is
circling Earth on a classified mission. Although its orbit
is officially unpublished, amateur sky watchers have spotted
it and are monitoring its progress. This week, a veteran
observer witnessed a spectacular flare from the X-37B,
exceeding the brightness of Venus. Details may be found on
today's edition of http://spaceweather.com.

SATURN'S RINGS SURGE IN BRIGHTNESS: This weekend, Saturn will
be at opposition--that is, opposite the sun in the skies of Earth.
Whenever this happens, Saturn's rings surge in brightness due to
backscattering of sunlight. Even a small telescope will show
the effect. Visit http://spaceweather.com for observing tips and a sky map.
