Apologies for the lack of space wx updates today. I’ve been attending a workshop about STEVE, a type of aurora that is mysterious and still new to science. Excited to share more about what we discuss after the workshop is over on Saturday :)

🌞 The Solar Wind: When the Sun Breathes Across Space Discover how the Sun’s solar wind shapes space weather, powers auroras, and affects life on Earth.

🌞 The solar wind flows from the Sun’s corona as charged particles. 🌍 Earth’s magnetic field deflects most, but some reach the poles. 💫 They spark colorful auroras, Earth’s luminous space‑weather signature.

Niño is a temporary global climate change resulting from unusually warm water in the central Pacific Ocean. El Niño can cause unusual or severe weather for some locations over the next few months. Warm water is shown in white in the above false-color picture taken by the orbiting TOPEX/Poseidon satellite in late October. The Pacific Ocean is color coded by sea surface height relative to normal ocean levels. The large white area represents a mass of warm water 30 times greater than all the Great Lakes, flowing toward the Americas. Although El Niños occur every decade or so, this year's is the first ever predicted. The cause and full effects of El Niños are still under study.

We continue to see protons in ACE EPAM rise. We may see the CME arrive soon, probably in the next few hours or sooner! Keep an eye out for the shock signature in solar wind L1 data.

Sunspots of 1 September 1859, as sketched by Richard Carrington. A and B mark the initial positions of an intensely bright event, which moved over the course of five minutes to C and D before disappearing.

The Carrington Event, the most intense geomagnetic storm in recorded history, peaked on September 1–2, 1859, during solar cycle 10. It created strong auroral displays that were reported globally and caused sparking and even fires at multiple telegraph stations.

Simulations prove early Earth's liquid core generated protective magnetic field Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged particles that make life difficult.

✨Earth's magnetic shield—a cosmic guardian!🛡️ It protects us from relentless space radiation, unlike Mars. What secrets do planetary shields hold? 🌌 #SpaceWeather

The NOAA ENLIL model shows impact from our M4.4 CME around 2025-08-08 at 12 UTC.

This would be Friday morning for NA timezones, so hopefully the CME arrives earlier than NOAA thinks.

Glancing blows are hard to forecast, so take exact timing with a grain of salt.

A screenshot of a graph of water levels from a station in Hawaii as the tsunami impacted the region.

Does water always recede prior to the arrival of a tsunami?

I was asked this yesterday after posting a graph of observed water levels at a station in Hawaii, which shows water levels first *increasing,* contrary to what many have heard about tsunamis.

The answer: no, not always! A thread... 🧵 1/9

#10. MAGNITUDE 8.6 (2012). Sumatra, Indonesia - Located off the coast of northern Sumatra, this quake produced heavy shaking, but only a handful of fatalities, mostly caused by heart attacks. #9. MAGNITUDE 8.6 (1950). Arunachal Pradesh, India - Referred to as the Assam-Tibet earthquake, this quake produced intense shaking, triggered sandblows, ground cracks, and large landslides across the region. All told, 780 people died. #8. MAGNITUDE 8.7 (1965). Alaska, USA - Located near the Rat Islands of Alaska's Aleutian Islands, this earthquake generated a tsunami that was reportedly 35 feet high. #7. MAGNITUDE 8.8 (1906). Esmeraldas, Ecuador - Referred to as the Ecuador-Colombia earthquake, this quake produced a strong tsunami that killed 1,500 and reached as far north as San Francisco. #6. MAGNITUDE 8.8 (2010). Biobío, Chile - Occurring offshore near the city of Quirihue, this intense earthquake killed 523 people and destroyed more than 370,000 homes. #5. MAGNITUDE 9.0 (1952). Kamchatka Krai, Russia - The world's first recorded magnitude 9 earthquake triggered a massive tsunami that struck Hawaii, causing over $1 million in damages. #4. MAGNITUDE 9.1 (2011). Tōhoku, Japan - Named the Great Tōhoku earthquake, this quake and subsequent tsunami killed more than 15,000 people and displaced 130,000 more. #3. MAGNITUDE 9.1 (2004). Sumatra, Indonesia -The Sumatra-Andaman Islands earthquake triggered massive tsunamis and killed more than 280,000 people while displacing 1.1 million across South Asia and East Africa. #2. MAGNITUDE 9.2 (1964). Alaska, USA - Often referred to as the Great Alaska earthquake, the Prince William Sound earthquake, or the Good Friday earthquake, this quake and ensuing tsunami killed 130 people and caused $2.3 billion in damage. #1. MAGNITUDE 9.5 (1960). Biobío, Chile - Commonly referred to as the Valdivia earthquake or Great Chilean earthquake, the largest earthquake ever killed 1,655 people and left 2 million homeless.

For some perspective: The recent earthquake off the coast of Russia has been revised to M8.8, which would tie the 2010 Chile and 1906 Ecuador quakes as the 6th strongest earthquake ever recorded.

We still have elevated solar wind conditions (Bt > 10 nT), but Bz is pinned north due to an unfortunately-oriented flux rope. This likely ENW (east-north-west) flux rope means Bz will remain positive as By rotates east->west (positive->negative). Flux ropes can last many hours.

TRACERS dual-satellite mission prepares to explore magnetic reconnection at Earth's cusp NASA's Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) mission, a collaborative effort led by the University of Iowa (UI) with substantial contributions from Southwest Research Institute (SwRI), has entered its final integration phase. NASA is set to launch TRACERS' two satellites into low Earth orbit on July 22nd from Vandenberg Space Force Base in California. The TRACERS mission will explore the dynamic interactions between the sun's and Earth's magnetic fields.

A view down into a mountain cirque, from above treeline; camera is on the continental divide at the edge of the Indian Peaks wilderness in Colorado. A stand of pine trees and krummholz are visible 400 feet below. In the background are several glacial lakes and a spectacular waterfall, with a snowy and rocky mountain ridge forming the skyline.

Here's where we camped Friday night (in the krummholz down below), after scrambling down next to the snowfield in the foreground. Gorgeous cirque, and a great reward for a 12-mile half-day (Amtrak dropped us off at noon, this was nearly 7pm)
