Two powerful X-class solar flares were recorded on November 4 \u2014 an X1.8 from Region 4274 and an X1.1 from a region just beyond the east limb. Both flares produced CMEs largely off the solar limb.<\/p>\n
Although the eruptions were not Earth-directed, NOAA forecasts minor to moderate geomagnetic storming from late November 6 into November 7 as a glancing shock from these CMEs may combine with an incoming coronal hole high-speed stream.<\/p>\n
The first X-class flare, an X1.8\/1b flare, erupted at 17:34 UTC from Active Region 4274 (\u2018beta-gamma-delta\u2019). The event produced Type IV radio emissions, a 160 sfu Tenflare, and a partial halo CME first visible in coronagraph imagery at 17:36 UTC.<\/p>\n
The CME was directed primarily off the northeast limb, and model analyses indicate that most of the ejecta will pass behind Earth. However, forecasters note the possibility of a shock enhancement reaching Earth late on November 6 to early November 7.<\/p>\n
