2019 Geomagnetic Storms

Post by Christopher K. » January 4th, 2019, 12:53 pm

Saturday 5 January: G1

Happy New Year! There were 221 spotless days in 2018, so when they show themselves, look! A lot of this "surface" activity is correlated to other activity like the material currently streaming out of this hole in the Sun's atmosphere...

This material may create G1 level conditions at the Earth tomorrow. G1 conditions include possible "weak power grid fluctuations"...

Saturday 24 January: G1

In addition to the G1 activity today, there was earlier (on 15, 16, 17 and 19 January) brief "unsettled" periods of geomagnetic field activity. There is a related Active Region near the center of the Sun's disk at this time.

Saturday 23 March: G2

Yesterday at 6:18am CDT, a C4 flare erupted from the Sun. It is likely that the Earth will receive some sort of CME component related to the flare.

Saturday 8 June: G1
Sunday 9 June: G1


A strongly-magnetized edge of plasma hit our magnetic field today. It's probably the edge of a coronal mass ejection (CME), which left the Sun Monday. Here is some video from STEREO-A...

Monday 5 August: G1

Tony Phillip's Spaceweather states the atmospheric hole is hourglass-shaped. Estimated time of arrival of the solar wind is Monday and/or Tuesday. Requests for "eyes to the skies" are being sent to the Southern Hemisphere, as it is experiencing winter and therefore there is more nighttime.

Saturday 31 August: G1

If any storm conditions occur, they will probably happen during the last half of Saturday. The absolute lower boundary for possible aurora sightings includes most of Missouri and a good deal of Kansas.

Sunday 1 September: G2

At this time, the Sun is optically quiet. Indeed, sixty-nine percent of the 2019 days so far have been spotless. However, with this G2 activity aurora could descend to Montana and Washington state.

Friday 27 September: G1

Today I explained to a homeschool group from Pointe Coupee that the Sun's surface activity comes and goes over an eleven-year cycle. Some are predicting a full-tilt Solar Maximum for 2023.
