X-Flare Alert: Major X-Class Solar Flare and CME from Large Sunspot AR3738

Departing Region 3738 produced an X1.9 (R3-Strong) flare that peaked at 9:26 a.m. EDT (13:26 UTC). The flare was associated with radio signatures that suggest a coronal mass ejection (CME) was likely associated with this activity, but due to its far southwestern location, an Earth-directed component is not anticipated. However, NOAA forecasters will analyze any coronagraph imagery as it becomes available. Radiation from the flare caused a deep shortwave radio blackout over the Atlantic Ocean: map. Transatlantic mariners and ham radio operators may have noticed loss of signal at all frequencies below 30 MHz for as much as an hour after the flare. #Xflare #CME #radioblackout Images credit: AIA/SDO, NOAA/SWPC, nemesis maturity channel, Music credit: YouTube Audio Library Lazy Laura - Quincas Moreira
