ANOTHER X-FLARE: Old sunspot AR3664 isn’t as big as it used to be, but it is still very active. On May 29th (1437 UT), it produced an X1.4-class solar flare.

SOME COMETS LIKE IT HOT: Yesterday, Sept. 17th, Comet Nishimura (C/2023 P1) made a close approach to the sun deep inside the orbit of Mercury (0.22 AU). The comet survived. Petr Horalek photographed it emerging intact from Mount Lysa in Sabinov, Slovakia:
Earth-facing Sunspot 3363
Greetings Kin,
NOAA reports an M6.8 class coronal event today. I don’t see the sunspot number in the report to see if it came from the huge Earth-facing AR3363. Yesterday’s CME came from a smaller spot on the lower right limb. CME’s are forecast with 40-45% chance of radio frequency disruptions in the higher atmosphere. Impacts are expected to reach Earth from the two from July 12-13, 2023.
I would have expected the size/shape of the sunspot to change after a projection, so we may yet to know what AR3363 might do.
Below, the update is included above the original Spaceweather post.

GEOMAGNETIC STORM WATCH: Minor G1-class geomagnetic storms are possible on July 13th when a CME is expected to pass close to Earth. NASA and NOAA models of the CME give different results. NASA predicts a glancing blow, NOAA a clean miss. Either way, a close encounter could disturb Earth’s magnetic field and produce high latitude auroras.

A SLOW-MOVING CME APPROACHES: Most CMEs take only a few days to cross the distance between the Sun and Earth. A CME that left the sun on April 15th might take a whole week. NOAA forecasters say the unusually slow-moving CME could hit Earth’s magnetic field on April 22nd, producing, at most, minor geomagnetic storms.
