The sun emitted three mid-level solar flares on July 22 and 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 whats called solar minimum when there are few to no solar eruptions – so these flares were the first significant events observed since April. They are categorized as mid-strength flares, substantially less intense than the most powerful solar flares.
