What's up in space
 

Metallic photos of the sun by renowned photographer Greg Piepol bring together the best of art and science. Buy one or a whole set. They make a stellar gift.

CME IMPACT: A CME hit Earth's magnetic field on Nov. 26th at approximately 0500 UT (Nov. 25th @ 9 PM PST). The weak impact did not cause a geomagnetic storm. Aurora alerts: text, voice.

MORNING CONJUNCTION: As dawn begins on Tuesday morning, look southeast to find Venus and Saturn less than 1° apart in the constellation Virgo. Venus is very bright, Saturn much less so. A small telescope will reveal the rings of Saturn and the gibbous phase of Venus. [sky map]

Dennis Fitts and John Stetson photographed the two planets converging over South Portland, Maine on Nov. 26th:

"The lighthouse in the foreground is Bug Light," explains Stetson. "Seeing the conjunction was a nice way to start the day on Dennis's birthday. This morning, the 26th, Saturn and Venus were separated by 0.8 degrees; tomorrow, the 27th, these planets will be separated by 0.7 degrees."

PRESTO! A HUGE SUNSPOT: Yesterday, sunspot AR1620 was barely visible. Today it is a behemoth wider than a half-dozen planet Earths. NASA's Solar Dynamics Observatory recorded the sunspot's rapid growth in a period of less than 20 hours on Nov. 25-26:

AR1620 has a beta-gamma magnetic field that harbors energy for strong flares. Because of the sunspot's proximty to the center of the solar disk, Earth would be in the line of fire of any eruptons. NOAA forecasters estimate a 30% chance of M-class solar flares in the next 24 hours. Solar flare alerts: text, voice.

  Near Earth Asteroids
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 November 26, 2012 there were 1353 potentially hazardous asteroids.
