The Sun's surface has been quite active overnight.

Region 4298 emitted an X1.1 flare at 05:01 UTC, 1.3x stronger than the M8.1 flare from region 4299 on 06 Dec. Since region 4298 is towards the eastern edge of the Sun, any associated CME is unlikely to impact earth.

Region 4299 has stayed active and there were two medium-strength flares at 00:10 and 6:54 UTC resp., not reported by SWPC yet.

Here is a link to a GOES-19 SUVI time-lapse video covering the past 11 hours. One can see eruptions of plasma that loop along the magnetic lines of force; some material falls back to the surface, other escapes into space.

Chances are excellent for some good aurora viewing tonight in the upper- and mid-latitudes, esp. in the latter half of the night in Canada and northern U.S. states, due to the anticipated passage of the CME from 06 December.

Keep those cameras ready!
