SOLAR ACTIVITY: If you have a solar telescope, point it at the sun today. A large and beautiful prominence is dancing along the eastern limb. Pete Lawrence sends this picture from his back yard in Selsey, UK:
Prominences are clouds of hydrogen held up by solar magnetic fields. This one is so big, Jupiter would fit through its arcs and loops with room to spare. Sometimes the magnetic field of a prominence will become unstable and explode, producing a Hyder flare. Hyder flares are rare, but watching for them can be very satisfying.

VENUS AND THE MOON: When the two brightest objects in the night sky get together, not even clouds can hold them back. Last night in Colorado, "Venus and the Moon shone right through the haze," says photographer and physics professor Jimmy Westlake:
Photo details: Fuji Finepix S2, ISO 400, 35 mm Nikkor lens at f5.6, 8 seconds.
The pair of heavenly bodies were barely 1o apart, combining in brilliance for an unforgettable display. In Wallsend, Australia, David Hough saw them in broad daylight while photographer P-M Heden found that they rivaled the streetlights of Vallentuna, Sweden. "It was marvelous," he says. Now the Moon is moving away from Venus en route to another close encounter--with Saturn on May 22nd. Stay tuned!
