CHANCE OF FLARES: NOAA forecasters estimate a 60% chance of M-class solar flares and a 10% chance of X-flares during the next 24 hours. The most likely source of any eruption is big sunspot AR1598. Solar flare alerts: text, voice.
BRIDE, GROOM, AURORAS: Space weather can have a big influence on human affairs--and we're not just talking about radio blackouts and power outages. Last night, photographers Ronn Murray and Marketa Stanczykova were married under the Northern Lights in Alaska, and according to the groom, it was space weather that brought them together:
"Marketa Stanczykova and I met after a she looked me up from Iceland when she found this image on the cover of spaceweather.com 1 year and 21 days ago," explains Ronn. "We became friends on Facebook and after shooting auroras together in Alaska we fell in love. So, we gathered a small group of friends and headed up to the University of Alaska's Poker Flat Research Range where the aurora is studied. Last night we said 'I do' in front of the AuroraCam for all the world to see." (continued below)
"This is a self portrait of the Aurora and wedding photographers celebrating their own love under the magnificent lights."
"The sky was dark and aurora activity was non existent until we pulled up to the observatory. As if by magic, the sky came alive and we were able to say our vows with a select group of incredible friends, the amazing aurora that brought us together, and the Aurora Cam as our witnesses. It was a day none of us will forget!"

MAGNETIC FROTH: Sunspot AR1598 has quieted down since unleashing an X1-class solar flare on Oct. 23rd. It might be the calm before the storm. The sunspot is still large and apparently potent, as shown in this image captured by amateur astronomer Sergio Castillo of Inglewood,California:
Castillo used a telescope capped with a "Calcium K" filter tuned to the light of ionized calcium atoms in the sun's lower atmosphere. Calcium K filters highlight the bright magnetic froth that sometimes forms around a sunspot's dark core. AR1598 is very frothy indeed.
Magnetic froth does not necessarily herald an explosion, but it does guarantee a photogenic sunspot. Scan the gallery for the latest images:

Potentially Hazardous Asteroids (PHAs
) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones
all the time.
On October 25, 2012 there were potentially hazardous asteroids. Notes: LD means "Lunar Distance." 1 LD = 384,401 km, the distance between Earth and the Moon. 1 LD also equals 0.00256 AU. MAG is the visual magnitude of the asteroid on the date of closest approach.
