This is an important event because this will give us a lot of information mainly about the sun and more about the solar system. STERO launched from Cape Canaveral Air Force Station which is in Florida.

STEREO sent back it's first images of the sun. It showed the sun has a super hot atmosphere and is a million degrees celsius.
-
A solar eclipse happened on the sun but it was not visible on Earth. It is strange because it is weird how it was not visible on earth.
-
A sunspot erupted unexpectedly. It made a huge cloud with gas and was equivalent to a space tsunami not waves of water but of boiling magnetism.
-
A high solar wind erupted on the far side of the sun. It is one of the first major activities STEREO has seen so far.
-
The two STEREO spacecraft observed a huge eruption on the sun which happened for thirty hours (went into September 27). Both of the spacecrafts watched it for hours in a row which is one of the first times this has happened.
-
The mission saw the whole sun for the first time ever.
-
STERO discovered 122 eclipse stars. Even though STEREO's main purpose was for the sun, it could see starts from up to 20 days away.
-
For the first time, the spacecraft for STEREO watched a storm go onto our planet. This could advance space weather forecasting.
-
A sunspot with little warning exploded. A big explosion happened with hydrogen atoms. It is very powerful and STEREO watched it for one and a half hours.
