R3 Event on 16 July 2024 from Region 3738

R3 Event on 16 July 2024 from Region 3738
published: Tuesday, July 16, 2024 14:18 UTC

Departing Region 3738 produced an X1.9 (R3-Strong) flare that peaked at 9:26am EDT (1326 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, SWPC forecasters will analyze any coronagraph imagery as it becomes available. Please continue to visit our webpage for the latest information and updates.
