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.

WEEKEND PLANETS: When the
two brightest objects in the night sky get together, not even clouds
can hold them back. Saturday night in Colorado, "Venus and
the Moon shone right through the haze," says photographer and
physics professor Jimmy
Westlake:

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!
