A powerful X1.4-class solar flare erupted from Active Region 4405 on March 30, 2026, producing a large coronal mass ejection (CME) and triggering renewed monitoring of potential space weather impacts, according to solar observation data. <\/p>\n
The flare peaked at 03:19 UTC, following an initial eruption at 02:47 UTC and ending at 03:44 UTC. It was accompanied by a strong Type II radio emission, indicating a fast-moving shock wave with an estimated speed of 1,872 km\/s, a sign that a significant CME was generated, News.Az<\/a> reports, citing The Watchers<\/a>.<\/p>\n Subsequent coronagraph imagery confirmed a wide CME propagating eastward into space, with scientists noting that a partial Earth-directed component cannot yet be ruled out. Further analysis is underway to determine its trajectory.<\/p>\n The event also produced a strong 10cm radio burst, which can interfere with sensitive systems such as GPS, radar, and satellite communications. Temporary radio disruptions were expected across regions including East Asia, Southeast Asia, Australia<\/a>, and the western Pacific.<\/p>\n \n \n Solar activity had been relatively low in the preceding 24 hours, but rising solar wind speeds, increasing from around 350 km\/s to 450 km\/s, along with shifting magnetic field conditions, signaled heightened space weather variability.<\/p>\n Forecasters also noted that geomagnetic conditions could reach minor storm levels (G1) due to coronal hole high-speed streams, with further disturbances expected through March 31 before easing later.<\/p>\n Scientists continue to monitor whether the CME will interact with Earth\u2019s magnetic field in the coming days.<\/p>\n
