FAST
CORONAL MASS EJECTION: A coronal
mass ejection (CME) exploded from the vicinity of
sunspot 1164 during the late hours of March 7th.
It leapt away from the sun traveling ~2200 km/s,
making it the fastest CME since Sept. 2005. A
movie of the cloud prepared by Karl Battams
of the Naval Research Lab shows a possibly substantial
Earth-directed component. This CME and at least
one other could brush against Earth's magnetic field
on March 9th or 10th. High-latitude sky watchers
should be
alert for auroras.
SUNSPOT
CONJUNCTION: On March 7th, shortly
after space shuttle Discovery undocked from the
International Space Station, the two ships flew
directly in front of the sun over Europe. Catalin
Fus of Krakow, Poland, had his solar-filtered telescope trained on sunspot 1166 and recorded this
amazing conjunction:
"I was surprised that I could
see Discovery flying around the station," says
Fus. "The shuttle is so small compared to the
ISS." Nevertheless, both silhouettes were clearly
visible alongside the sunspot. Browse the links

more | Another great night in Abisko! I was very happy to see an aurora watch posted on spaceweather.com tonight just before heading to work. As I was eating dinner a friend of mine called me and told me to stop whatever I was doing, grab my camera and RUN outside. Needless to say I was not disappointed when I saw what was waiting for me outside!! The auroras just keep getting better. I cant wait to see what the last few weeks of this great season have to offer!! Shot with a Nikon D7000, Tokina 11-16 2.8, and 1 to 3 second exposures (this was a BRIGHT aurora!).
