Hawaii and later the California coast. Its impacting Hawaii now.

For those tracking the #tsunami, it has reached the Midway Islands. The signature is unmistakable, far above statistical error levels. This is not a warning to blow off. Please contact those you know who may be in harm's way. From the map, impact will occur in less than 2 hours.

Finally, from STEREO-A imagery, it does look like three separate eruptions. Remember, STEREO-A is looking at the Sun from the west side, so the signatures will not look like halos from STEREO-A's perspective. But you can clearly see the bright fronts of each stacked in close proximity.

Looking at NOAA's recently released run, it seems SWPC might have modeled a two-part eruption. The stronger part being directed slightly eastward of Earth, while the weaker part directed more towards Earth. This is likely why NOAA believes we won't see much of an impact until early July 27.

Now, it looks like NASA chose to model this multi-part eruption as a single storm because the coronagraph signature was so complex. Their model run shows essentially a direct hit early on July 26, circa 0400 UTC.

In actuality, there are multiple partial halos in this complex structure-- one that launches to the east, one more northward, and another structure that launches a bit more southward. I will go over this in more detail in my upcoming forecast.

Now, here is what makes things interesting. These eruptions happened so close together that in coronagraphs they look like a single structure launching to the east side of the Sun, but that is not consistent with the location of the main filament launch, which was west of center disk.

To break things down a bit more simply, here is a detailed animation that shows the scars created by the two bits of the complex eruption that are Earth-directed. These dark scars are highlighted by the ovals and show where the final two bits tore off from the Sun.

Next, early on July 23, the filament near center disk (see arrows) launches slowly. This is the main Earth-directed eruption. Then by mid-afternoon on July 23, Region 4149 finally lets go of the remaining material connected to the filament. It is a three-part process that is deceptively complex.

Our Sun rapid-fire launched multiple #solarstorms, but they were so close together in time that they look as if they are one structure in coronagraphs. A thread 🧵. Late on July 22, you can see a slight "puff" just to the east of Region 4150. This launches the first solar storm and sets the stage.

It was inevitable this kind of #SpaceWeather effect would become more noticeable considering the explosive growth of the commercial space industry and developing countries' emerging government space sectors! www.sciencealert.com/mysterious-r...

Aww! Much thanks. It is an extremely eye-opening science, but still so much in its infancy. It's also a controversial topic, so finding robust research by pedigreed medical researchers is a bit tricky. One needs to know where to look!

Thanks for sharing Andy!

The post reads, "Today, June 26th, the #aurora was spotted on a live camera heading towards #Mt_Katahdin at #Millinocket Lake (45°44′N) in #Maine, USA. A #green aurora appeared, sometimes accompanied by #pillars. It was a beautiful time before dawn."

WOW I just read this thread. So glad my forecasts help! Indeed, a growing community of folks are realizing they are susceptible to space weather. Im actively engaged with MDs at Harvard & U of Minnesota doing heliobiology research. More is coming. Thanks to @paullecomtephoto.nz for the introduction.

Activity ramps up due to some fast #solar wind from a coronal hole entering the Earth strike zone now. #AuroraAustralis chasers at high latitudes could get a decent show through June 28. Expect views to be more sporadic at mid-latitudes. Amateur radio operators expect a full forecast for Field Day.

Region 4114 strikes again with an X1.75-flare at an R3 #RadioBlackout level. Expect radio communication degradation through the Asian Pacific, China, Australia, New Zealand, as well as in the Western Hemisphere over the next hour (see colored regions in map). A #solarstorm may also be launching.

Overall, the Sun is remaining extremely active this week, launching many solar storms, as we can see in this SUVI 304A view. Despite the activity, none of these storms are truly Earth-directed. However, this could change very soon!

Here is the SUVI 131A view showing the location of the big flare X-flare today. Notice the new region flaring on the Sun's east limb!

Region 4114 fired an X1.27-flare today causing a R3-level #RadioBlackout (watch the lines disappear in the colored regions of the map). No #solarstorm launch, but the region is crossing through the Earth strike zone now. A new X-flare player also rotates into view now, so expect more big flares!

Yes, it is a gorgeous display! This filament channel continues to fill and release. It is the same channel participated in that massive Earth-directed eruption back on June 8. That is the one where I joked the eruption took the Sun's face off!

Our Sun gets busy! Big flare action from Region 4114 continues, causing increased risk for #RadioBlackouts and #RadiationStorms. A wide coronal hole brings extended fast solar wind & #aurora views through this week. Region 4105 launches some gorgeous eye candy near the west limb!

During the #solarstorm launch, a strong blast wave occurs, but it propagates mainly northward. So the main structure was launched towards the northern pole of the Sun. However, Region 4114 is crossing the Earth-strike zone now, so we could see an Earth-directed storm launch yet!
