Solar Storm Heading Our Way

By Nancy Atkinson - August 3, 2011 at 6:54 PM UTC | Solar Astronomy

Early today, (Aug 3, 2011) two active regions on the Sun, sunspot 1261 and 1263 unleashed solar flares, which was captured by NASA's Solar Dynamics Observatory. The above video shows an M6 class flare from 1261 in a couple of different wavelengths.

SolarstormWatch,

a citizen science project through the Royal Observatory in Greenwich, England predicts the solar storm from the larger flare to reach Earth at 15:00 UTC on August 5, 2011, and also predict direct hit on Earth.

See below for a graph of the activity:

Solar storms are a concern if they hit Earth directly since under the right conditions, they can create extra electrical currents in Earth's magnetosphere. The electrical power grid is vulnerable to any extra currents, which can infiltrate high-voltage transmission lines, causing transformers to overheat and possibly burn out.

She is currently retired from daily writing, but worked at Universe Today for 20 years as a writer and editor. She also contributed articles to The Planetary Society, Ad Astra (National Space Society), New Scientist and many other online outlets.

Her 2019 book, "Eight Years to the Moon: The History of the Apollo Missions,” shares the untold stories of engineers and scientists who worked behind the scenes to make the Apollo program so successful, despite the daunting odds against it. Her first book “Incredible Stories From Space: A Behind-the-Scenes Look at the Missions Changing Our View of the Cosmos” (2016) tells the stories of 37 scientists and engineers that work on several current NASA robotic missions to explore the solar system and beyond.

Nancy is also a NASA/JPL Solar System Ambassador, and through this program, she has the opportunity to share her passion of space and astronomy with children and adults through presentations and programs. Nancy's personal website is nancyatkinson.com
