First X-class flare of SC25
An X1.5 flare was produced on 3 July (peak at 14:29UT) by a region that started to develop only late on the previous day. Its location was very close to the northwest limb making an accurate assessment of its magnetic complexity difficult.
HF communications were most likely briefly disturbed over Greenland, the North Atlantic and Brazil (D-RAP - D Region Absorption Predictions (D-RAP) | NOAA / NWS Space Weather Prediction Center )
