Space Weather News for Jan. 31, 2005

FAR SIDE OF THE SUN: Remember giant sunspot 720? On Jan. 20th it exploded,
sparking bright auroras over Europe and the most intense proton storm in
15 years. Since then the 'spot has been transiting the far side of the
sun, carried around by our star's 27-day rotation.

Although sunspot 720 is on the sun's far side now, it's not out of sight.
Using a technique called helioseismic holography, solar physicists can
take pictures of the sun's far side--and they've seen sunspot 720 there.
If the active region holds together a while longer, it could turn to face
Earth again in early- to mid-February.

COMET MACHHOLZ: With the bright Moon waning, now is a good time to see
Comet Machholz again. Step outside after sunset and face north. You'll
find the comet near the W-shaped constellation Cassiopeia. It looks like a
faint fuzzball, barely visible to the unaided eye but an easy target for
binoculars or a small telescope.
