Absolutely insane! Yesterday's X1.1 class #SolarFlare was observed in high resolution by the NASA IRIS mission. IRIS observes with a small field-of-view, so catching the largest flares is rare. But just look at this, I haven't seen a flare observation this cool in a long time. ☀️ https://pic.twitter.com/FB6IR47ORt
