If you’re looking for intelligent, easy to “get up to speed on” lessons on the sun, go to Youtube and review “Suspicious0bservers”. He also has a website.
Ben Davidson is a PA resident who has been studying the sun for over a decade. He, and other colleagues have created earthquake prediction models that recently received successful peer review and are now accepted science - his work is saving lives.
Suspicious0bservers.org too, but you have to pay for that site.
