Upcoming NASA/NSTA web seminar on Solar Activity and Space Weather.
Dr. Therese Kucera, a solar physicist working at NASA's Goddard Space Flight Center in Greenbelt, Maryland, will be giving an NSTA web seminar on Solar Activity and Space Weather Dec. 14, 6:30-8:00 EST. The target audience is teachers of grades 4-9. Pre-registration is required, but anyone can sign up. This is part of an on-going series of web seminars.

STEREO will be featured on Discovery HD, Dec 29 at 10:00pm. They will be using a lot of video products that Walt Feimer and APL created to support STEREO.

P2 burns on STEREO A & B were both very successful. The instruments were turned off for an eclipse at perigee (about 25 minutes). Both spacecraft came out of eclipse without any problems. All the instruments were turned back on without problems. The A2 burn & P2 burn look so good on spacecraft A that the spacecraft will not need to do any more burns. It is now on a trajectory to get to lunar swingby and its 22 degree drift orbit. The spacecraft B has two lunar swingbys, so it is much more sensitive to errors. The mission may have to do one more burn on spacecraft B closer to the lunar encounters.

This is STEREO’s second week in Earth orbit(s). The execution of the apogee propulsive maneuvers on both spacecraft successfully raised their perigees to altitudes that are comfortably above the atmosphere. Currently, both observatories are operating nominally. All subsystems and instruments on both observatories have a GREEN health status. The Delta II 3rd stage reentered the atmosphere on Sunday evening 7:48 pm at a point 600 miles east – north-east of the U.S. Virgin Islands. Those interested in tracking STEREO through their early orbits can get information at the Advanced Plasma Laboratory orbit website.

The IMPACT booms successfully deployed today. They are now stretching out into space from the spacecraft body (bus). They hold IMPACT instruments far from the spacecraft's electrical and magnetic contamination. Congratulations to the boom team: Robert Ullrich, Jeremy McCauley and Paul Turin!

Here is a continued update from the launch activities: Launch was near perfect so there is plenty of fuel for an extended mission. STEREO WAVES (S/WAVES) powered up and antennas were deployed. Everything is running smoothly with SWAVES and the instruments have observed the first solar burst (a commonplace type III from flare). The satellites will turn on their "thrusters" at apogee (highest point in their orbit) today to change orbits. The SECCHI doors opened a tiny bit successfully. The heaters have been turned on and were detected by SWAVES and MAG.

The IMPACT instruments: Magnetometer (MAG), Suprathermal Electron (STE), and Solar Wind Electron Analyzer (SWEA) on both STEREO spacecraft were successfully powered up.

The STEREO satellites are healthy, tracking stars, and communicating with Earth. Instrument tests start Oct. 27th.

STEREO successfully launched today at 8:52pm EDT! STEREO was launched into an almost perfect Florida night sky last night and successfully went into its elliptical transfer orbit. Spacecraft were separated and solar panels deployed within approximately a half hour of launch.
You can read more about it on the NASA STEREO webpage.

Many articles about STEREO came out in anticipation of the launch. Co-Investigator, Dr. Janet Luhmann, was part of the press interview panel at the STEREO launch facilities. Furthermore, KTVU's 10 O'Clock News ran a snippet on STEREO. Watch Laura Peticolas and Janet Luhmann appear on TV!

NASA aids in resolving long standing solar cycle mystery - The Sun's 11 year sunspot cycle is a cycle that varies from a dynamic and active Sun, throwing off large quantities of mass and x-rays as solar storms, to a quiet Sun with very few solar storms.

Take a survey about SEGway’s Exploring Magnetism lesson guides:
Supplies are running low on SEGway’s printed booklets of the Exploring Magnetism educator guide, plus we have just completed a new guide in the series: Exploring Magnetism in Solar Flares.
To help us decide whether or not to print more copies of these guides or to produce CD-ROMs containing all the Exploring Magnetism guides please take our survey at http://www.surveymonkey.com/s.asp?u=671391810708
