One of the strongest flares of cycle 25 and aurora

Active regions 14274, 14272, and 14275 predicted  by GONG's farside imaging continue producing strong flares and CMEs. This enhanced solar activity also produces strong geomagnetic storms and aurora. Last  night (11 Nov 2025), the aurora was observed as far south as Santa Fe, New Mexico, USA. Photo shows aurora in Denver, Colorado. On 11 November 2025, AR14274 produced a very large solar flare of X5.1 class. More aurora displays to come! Video shows flare as observed in H-alpha by GONG station at Teide Observatory, Canary Islands, Spain.
