Active region #1429, the source of several major flares, CMEs, and radio blackouts earlier this month, has made it all the way around the sun. The STEREO spacecraft followed it across the far side, and now it is just becoming visible on the limb. It is still flaring regularly, and producing large CMEs which are only marginally geoeffective at this point.
Expect daily solar fluxes to rise out of the 100 range, and K indices to approach the event threshold as this region continues its movement across the disk, and as a full-halo CME from another region on March 27 UTC approaches our planet. In addition, C class flares are likely, and M class is not out of the question.

Auroral Event In Progress
Check out the photos of incredible aurora at high geomagnetic latitudes at this Daily Mail photo story.
The past two Kp indices have been 3, below the storm threshold. As the news story notes, this was not a severe storm. While energetic particles are traveling at a high velocity, most are missing the Earth. HF propagation will not take a major hit from this one, although some signals from transauroral paths do seem much weaker or missing tonight.

Planetary K Index Now = 5
We have crossed the minor storm threshold. Expect degradation of high-latitude paths, and perhaps a nice auroral show tonight in the northern US.
Geomagnetic Event Commences On Schedule
Space Weather News for Jan. 24, 2012 http://spaceweather.com CME IMPACT: As predicted by analysts at the Goddard Space Weather Lab, a CME hit Earth's magnetic field on Jan. 24 at ~1500 UT (10 am EST). A geomagnetic storm is brewing in the aftermath of the impact, but as this alert is being written it is too soon to say how weak or strong the storm might be. High-latitude sky watchers should be alert for auroras after local nightfall; the hours around local midnight are often best for seeing the Northern Lights. Chances for a good display favor observers in northern Europe, Greenland, Iceland, Canada, Alaska, and possibly northern tier US states such as Maine, Wisconsin and Minnesota. Check http://spaceweather.com for updates.
Local news media seem awfully excited about this event. So far, one K index of 4 has been recorded, and HF propagation seems to be holding up. Keep watching...

Solar: Stand By For Action!
An energetic, flaring region has just become visible to Earth in its rotation on the Sun's surface. Propagation disturbances, and hopefully some higher solar fluxes, are likely.

Start Watching the K Index
Breathless news reports indicate magnetic fluctuations, and one has even blamed it for an earthquake. (Not likely.)
The K index comes out every 3 hours, and measures the most disturbed of three axes on standard magnetometers on a quasi-logarithmic scale from one to nine. The high latitudes will be affected first. Paths from places like Japan will degrade. When the Boulder ("WWV") K index rises, you know it's happening.

The Boulder K index is still only 2 right now, but this is supposed to change when a CME gets here Tuesday UTC.

Here comes the sun storm
Alan Boyle writes: NASA's Solar Dynamics Observatory has captured what appears to be a disturbance in the force - on the sun. Astronomers say Sunday morning's eruption sent out a blast of electrically charged particles that should create brilliant auroral displays on Tuesday night.
"This eruption is directed right at us, and is expected to get here early in the day on August 4th [UTC? -Hugh]," astronomer Leon Golub said in a statement from the Harvard-Smithsonian Center for Astrophysics. "It's the first major Earth-directed eruption in quite some time."

Shuttle Docks; SDO Scrubs
You know about the shuttle already, so let's get to SDO, the Solar Dynamics Observatory. This payload's been awaiting launch forever. It's a unique mission, and one that's very interesting for those of us who live and breathe radio propagation.
Basically the SDO will ultimately reach geosynchronous orbit over New Mexico, from which it will return absolutely unprecedented data from observations of the sun at an absolutely mind boggling data rate. It will be able to fill a CD's worth every 36 seconds! This requires a dedicated ground station, with dishes pointed at SDO's stationary spot in the sky.
SDO scrubbed this morning after wind violated launch constraints. The Atlas booster's computers auto-aborted the count at T-3 minutes. The next opportunity is Thursday morning at 10:23 a.m. - 11:23 a.m. EST (1523-1623 UTC).
The SDO Launch Blog is here.
You can also follow SDO on twitter. Tweets are written in the first person, as if the payload is talking. They're fun and informative, and SDO has a huge following.
This mission's going to be good.
