Massive sunspot chain AR 4366 is one for the record books. In just the span of a few days, the group has grown from near obscurity to a monster, more than 200,000 miles in length. For context, the chain would nearly stretch from the Earth to the Moon...though placing it there would fry us all in the process.
You can currently safely see the sunspot group with eclipse glasses… no magnification needed. It’s also crackling with potential energy in a ‘beta-gamma-delta’ configuration aimed Earthward today, and sent off yet another X-class flare earlier this morning. We may see a glancing blow from Sunday night’s X-8 flare over the next 24 hours. Some interesting spaceweather times ahead. https://www.youtube.com/watch?v=p1tRsmho_TY
