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 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.

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.

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.

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

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.

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.

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

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.

41,000 years ago, Earth's magnetosphere collapsed to 10% strength: auroras at the Equator, cosmic rays, and UV bombardment for 700 years. How did our ancestors survive? With surprising innovations!

NASA's TRACERS mission successfully deployed its first payloads, including the PExT tech demo and REAL CubeSat, to study Earth's magnetosphere and solar wind interactions.

The twin satellites will orbit the poles, enhancing space weather understanding.
