Geomagnetic Storm Strength Increases


Geomagnetic storms due to coronal mass ejections (CMEs) earlier in the week have increased in strength, and are now rated a G3 on a scale from G1 to G5.

This space weather is due to the March 7 activity from the sun that caused rapid changes to the shape of Earth’s magnetosphere – the bubble of protective magnetic fields surrounding the planet — resulting in a geomagnetic storm. As of March 8, the storm was fairly mild since the magnetic fields from the CMEs were partially aligned with Earth’s own and thus slid around the magnetosphere. However, the geomagnetic storm has increased because the magnetic fields of the CMEs have now changed direction such that they can more easily deposit magnetic energy and radiation into Earth’s environment.

NASA Tweetups Are Evolving. It’s Time To Be More Social


NASA is expanding its successful program of Tweetups to include more social media platforms, broadening the agency’s use of social media to engage audiences about the agency’s mission of exploration and discovery. As part of this effort, the “NASA Tweetup” will now be known as “NASA Social.”

Since 2009, NASA has hosted 34 in-person Tweetups, which are informal meetings of people who use the social messaging medium Twitter. Hundreds of participants have shared thousands of tweets, pictures, videos and blog posts with their followers, detailing behind-the-scenes views of NASA launches, centers, missions and speakers. The agency’s primary Twitter account, @NASA, has nearly 2 million followers. Multiple NASA missions and centers maintain Twitter accounts as well. NASA’s innovative use of Twitter has been recognized as one of the best in federal government.
