About this work
The sun emitted three mid-level solar flares on July 22-23, 2016, the strongest peaking at 1:16 am EDT on July 23. The sun is currently in a period of low activity, moving toward what's called solar minimum when there are few to no solar eruptions – so these flares were the first large ones observed since April. They are categorized as mid-strength flares, substantially less intense than the most powerful solar flares. These flares were classified as M-level flares.
