This is the fourth X-class solar flare since November 9, and the sixth since November 4. If we look just at Region 4274, this is its fifth X-class since X1.8 at 17:34 UTC on November 4, X1.7 at 07:35 UTC on November 9, X1.2 at 09:19 UTC on November 10, and X5.1 at 10:04 UTC on November 11.<\/p>\n
A Type II Radio Emission, with an estimated velocity of 1 525 km\/s, was associated with today\u2019s X4.0 event, suggesting a coronal mass ejection (CME) was produced.<\/p>\n
Source Region 4274 is positioned near the west limb of the Sun, a location that generally reduces the likelihood of producing Earth-directed CMEs. However, if the eruption generates a halo CME, it would still be expected to contain an Earth-directed component despite the unfavorable geometry.<\/p>\n
Radio frequencies were forecast to be most degraded over SE Africa and the Indian Ocean at the time of the flare.<\/p>\n
