SDO: The Solar Dynamics Observatory launched on 2-11-2010 ... to study solar variability ... its impacts on Earth ... by studying the solar atmosphere in many wavelengths simultaneously ... how the Sun's magnetic field is generated and structured ... how it forms solar wind, energetic particles, and variations in the solar irradiance ... how Space Weather comes from that activity. This recurring diary highlights that solar activity.
Citizen Scientists use the images from SDO in their own projects. One such project is on Youtube channel GeeMackVideo. The SDO image data is publicly available soon after being received by the science teams. Images are provided at a rate of about one per channel every 15 minutes. The following video is from this morning as the AIA/HMI instrument was rotated to complete an alignment. The process took about 10 hours to complete. Yes, GeeMack has a sense of humor.
Just after the video starts, click the icons like the ones below these colored arrows for HD and full screen.

The Solar Dynamics Observatory (SDO) generates an enormous amount of data as it monitors the Sun's activity. It is a sun-pointing spacecraft making nearly continuous observations with an almost constant data downlink of 130 Megabits per second. The spacecraft is 4.5 m x 2 m with a mass of 3100 kg. One of the instruments is the Atmospheric Imaging Assembly (AIA).

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
