Large amounts of plasma (consisting of mostly electrons and protons) ejected from the sun.
Gamma-Ray Bursts
Short bursts of gamma-rays (very high frequency electromagentic radiation) with very energetic explosions. These bursts can last from a few milliseconds to a few about an hour.
Geomagnetic Storms
A disturbance in the Earth's magnetosphere caused by changes in space weather such as solar erutptions.
The region around the sun that is filled with the Sun's gases, solar winds, and magentic fields.
The magnetic field produced by the Sun that is carried through by solar winds.
The uppermost part of the atmosphere. It also forms the inner surface of the magnetosphere and is reponsible for radio communication between distant places on Earth.
Lagrangian Point
Equilibrium points in space where the gravitational pull by a massive body is equal to that of another body.
Forms when a stream of charged particles, such as a solar wind, interacts with the magnetic field of a planet.
The surface of the sun that you see.
Solar Eruptions
These are sudden intense bursts of energy in the sun. They may develop in a few minutes and last for several hours.
Solar Wind
A constant stream pf charged particles, such as electrons and protons, that are continuously ejected from the upper atmosphere of the Sun.
Suprathermal Ions
Ions, charged particles, that have more energy than similar particles of the same type.

STEREO has a new launch date: April 11, 2006.

May 1 - 4, 2005

The STEREO working team meeting took place in Hamburg, Germany at the Hamburg Planetarium. Several news articles were written about the meeting after a STEREO press conference in Hamburg. One article was written by the DPA news service, a German wire service akin to the Associated Press. Google and Yahoo showed about 40 newspapers/webpages picked up the story. There was also a TV story on STEREO and an article in the STERN magazine. Most of the articles quoted Mike Kaiser of NASA and Janet Luhmann of Berkeley. Volker Bothmer was also quoted along with Thomas from the Planetarium.

Progress Report on Spacecraft Integration:

Dave Curtis and Jeremy McCauley successfully delivered the FM1 IMPACT Boom with SWEA, STE and MAG FM1s attached, to APL last week. It was bolted to the spacecraft as a fit-check (see image). Looks great! It came off until a SWAVES box gets attached in the next week or so. Thanks to all the Boom suite participants for reaching this milestone.
Still need to finish up environments test on the SEP suite and remaining tests and delivery on the Boom suite FM2.

Mach 16, 2005

Dave Curtis (UC Berkeley Space Sciences Laboratory) has visited APL to deliver the very first peice of STEREO instrument hardware for integration into STEREO-A. View an image of FM1 IDPU box here.

Dr. Laura Peticolas gave a talk at the American Association of Physics Teachers on the STEREO-IMPACT Sounds of Space project. Find out more about this project here.

he two magnetism teacher's guides, "Exploring Magnetism" and "Exploring Magnetism in the Solar Wind" were printed and are ready for teachers to use in the activities and worksheets in their classrooms! They are available online here or email us at outreach@ssl.berkeley.edu FIX THIS LINK and request the printed guides to be sent to you.
