New Delhi: A cluster of sunspots designated as Sunspot Group 687 by the Solar Influences Data Analysis Centre (SIDC) operated by the Royal Observatory of Belgium and Active Region 4274 by the US National and Oceanic Administration (NOAA) has fired off the fifth X-class solar flare. The X4.0 solar flare lasted for nearly an hour, peaking at 08:30 UTC on 14 November. After rotating into view, AR 4274 fired off an X1.8 solar flare , the first X-class outburst since June. This solar flare was not aimed at the Earth, but the sunspot cluster erupted in three more flares while crossing the central meridian of the Sun, all of which were aimed straight at the Earth.

AR 4374 produced an X 1.7 flare on 09 November, followed by a long-duration X1.2 flare on 10 November, and then an X5.1 flare
