We will likely hit G4-levels (Kp 8) putting us at the "severe" storm level. Hp60 has reached even higher. But no worries, this intensity will subside as we exit the sheath region and solar wind density drops. Magnetic field is flipping now too so all is good. Enjoy the

First we saw, Crimea, then Turkey, then Greece and now China! This is the second time this year we have seen
#aurora
in China. Well done
#SpaceWeather
community! Your reporting has gone above and beyond my wildest expectations! Thank you all for spotting
#aurora
around the globe!
Stunning! The red and green auroras were dancing together in harmony in
#Mohe
, north China's
#Heilongjiang
Province on the evening of Nov 5. This is the first time that green
#aurora
dancing has been recorded on video in
#China
.

This has got to be one of the coolest things I've ever seen a pilot do unannounced for passengers aboard! Spreading the
#SpaceWeatherLove
through an airborne

panorama!
The pilot of this Finnair flight made a 360 turn to allow everyone onboard see the fantastic Northern Lights last night.

X1.9-flare now! Region 3590 fires a big flare at an R3-level
#RadioBlackout
over the Western Pacific, especially Western USA & Canada, New Zealand, Eastern Australia & Indonesia (colored regions in map). Although short-lived, expect more activity from this region!

Two, Three or not Two, Three? For those who missed the
#aurora
, we have two, if not three more
#solarstorms
headed for Earth! NASA models show impact beginning early August 4 for the first, a drive-by graze for the second late the same day, & the third hitting early on August 5.

One of the early glancing
#solarstorms
has arrived and it is stronger than predicted. Even though this is a slow storm, the high density & strong magnetic field should cause
#aurora
to brighten quickly. High-latitudes should already be getting shows. Mid-latitudes, stay ready!

X-1.35 Flare! Region 2975 fires again with a possible Earth-directed

too! Expect waning

The new

forecast is up! Learn the details of back-to-back incoming

users groan this week.

Strange to see satellite startups feeling blindsided by how much orbit degradation their LEO sats experience & how much fuel it takes to keep them aloft now that solar activity has increased. This is exactly what I (along with others) forewarned years ago.

More than a glancing blow! NOAA prediction model shows the Earth-directed
#solarstorm
launched yesterday should impact early on August 1. NASA concurs. G1-G2 storm conditions possible, with
#aurora
views possibly through August 2.

Even as we enjoy
#aurora
from this ongoing G3
#solarstorm
, our
#Sun
launches yet another, near region 3386. This one comes with a
#RadiationStorm
as well.
#GPS
users, HF
#radio
operators, &
#aviators
be wary of potential communication & navigation issues at high latitudes now.

The first of at least two
#solarstorms
has hit! Impact is mild thus far. The storm magnetic field is northward so
#aurora
remains at high latitudes. If the field turns southward & the speed stays the same, aurora shows will improve. For now enjoy a boost in HF
#radio
propagation!

Fast Hit or Slow? An Earth-directed
#solarstorm
is on its way to Earth, but NASA & NOAA predictions disagree on impact time. NASA (shown below) says impact will be near midnight March 28, but NOAA believes 18 hours earlier. Either way
#aurora
could reach to mid-latitudes! (1/2)

The Sun aims south! A partly Earth-directed
#solarstorm
launched today. NASA & NOAA agree, a glancing blow is expected early November 30. This one is going mainly south of Earth so minor effects expected.
#Aurora
possible at high latitudes,
#GPS
& amateur
#radio
impacts minimal.

Our
#Sun
celebrates
#July4
with its own special fireworks! We have two partly Earth-directed
#solarstorms
(aka CMEs) on their way. The second storm will catch up to the first giving us a 1,2-punch. Model predictions show impact likely July 7. I'll post NASA model runs next.

Today's R3-level
#RadioBlackout
from the X3.38 solar flare caused severe amateur radio communication impacts over the Atlantic. Now the ongoing
#RadiationStorm
has reached the S2-level.
#Aviation

#UAV
pilots check ICAO advisories often, especially if flying near the poles.

At long last we have a
#solarstorm
coming (somewhat) towards Earth. The NASA prediction model run indicates we could have a glancing blow by early February 7. Mild effects to
#GPS
reception & amateur
#radio
are expected, but chances for
#aurora
increase by late Monday evening.

Surreal! Owens Peak is south of Las Vegas and about 100 miles east of Bakersfield, California, USA. Seeing pillars so high in the sky at this latitude is nothing short of spectacular. Thanks for reporting!
Never thought I’d see the
#NorthernLights
in Southern California! 😱🤩 I took this pic on my phone, no filter! In the Owens Peak Wilderness in the Southern Sierra.

M4.8-flare now! Region 3088 fires it's largest flare yet. Just like the other flares from today (shown below) expect an R1 (near R2-level)
#radio
blackout on Earth's dayside (especially Alaska, Hawaii, Asian Pacific, Northern Australia, India, & East Russia) over the next hour!

Quite possible. Recent X-flares from Region 3590 are showing radio bursts beyond 12 GHz. This could degrade radio signals way beyond the L-band (e.g. those used by GPS, satellite phones), impacting signals clear up to the X and Ku bands (e.g. those used by Starlink and NASA).
@TamithaSkov
Could this interfere with the Odysseus comms? Just curious.

Ready for a 1,2-Punch? Our
#Sun
launches a big Earth-directed
#solarstorm
on the heels of fast
#solar
wind! NASA & NOAA predictions disagree, but give an impact window of 06:00-20:00 UTC Dec 9. If it arrives early, expect
#aurora
& HF radio issues deep in mid-latitudes for 48hrs!
