A Large Sunspot

AND a Juno update.  First take a look at this sunspot.  The spot is named AR2665 and it is huge.  Estimates are about 120,000 km / 74,560 miles from end to end and its a configuration that is not all that stable.  If this thing were to let off a flare, it could be an M-class and would be directed straight at us likely to produce vivid auroras at the least.

The image comes from the Solar Dynamics Observatory using the onboard Helioseismic and Magnetic Imager (HMI) is one of three instruments aboard the Solar Dynamics Observatory(SDO) designed to study oscillations and the magnetic field at the solar surface. HMI observes the full solar disk at 6173 Å with a resolution of 1 arc second.

The Juno spacecraft successfully flew over the Great Red Spot of Jupiter at a distance of only 9,000 km / 5,600 miles. Images to be released on 14 July.
