Astronomical Halloween: The Jack-o-lantern sun

The sun looks to have pulled out its Halloween costume for the season, dressing as a classic jack-o'-lantern!

In actual fact, this picture was taken on October 8th 2014, but is perfect for today. The most active regions of the sun show up brighter and make the sun appear as our favourite carved pumpkin.

The shot was captured by NASA’s Solar Dynamics Observatory which launched on February 11th 2010, with the mission to study how the sun creates solar activity which drives space weather.

This is no easy task and the SDO is not just a camera looking at the sun. It takes measurements of our solar system’s biggest star from the interior to the atmosphere, the magnetic field, and energy output.

Solar activity such as solar flares can have a huge impact on Earth’s communications systems. Where there is a strong solar storm, it impacts GPS systems, radios, and other ways of communicating on our very own planet.

Make sure the sun, and clouds, are going to behave for Halloween tonight by keeping check on the WeatherRadar through the day.
