X-Flare!

July 29, 2024 @ 02:50 UTC (UPDATED)

An X1.5 solar flare was just detected around AR 3764/3766 peaking at 02:37 UTC (July 29th). The active region is now directly facing our planet and is in a great
position for potential Earth directed eruptions. A small plasma wave appears evident in updated AIA imagery so a weak CME may have been produced. A major eruption of
plasma is unlikely.

Stay tuned to SolarHam.com for the most up to date information regarding this event.

ALERT: Type II Radio Emission
Begin Time: 2024 Jul 29 0236 UTC
Estimated Velocity: 535 km/s

SOLAR ACTIVITY IS HIGH: Sunspot complex AR3765-67 is crackling with strong flares--and they're getting stronger. An impulsive X1.5 flare this morning at 0237 UT caused a deep shortwave radio blackout over Japan, southeast Asia and Australia (map). More X-flares are in the offing as the sunspot complex turns directly toward Earth later today.

CANNIBAL CME ALERT: A series of M-class flares over the weekend hurled multiple CMEs toward Earth. According to a NOAA model, the first two CMEs merged to form a potent Cannibal CME. Strong G3-class geomagnetic storms are possible when it reaches Earth on July 30th. Subscribers to our Space Weather Alert Service will receive an instant text message when the CME arrives.

The Cannibal CME is clearing the way for 2 or more CMEs following behind it. SOHO coronagraphs show a wagon-train of clouds leaving the sun on July 28th:

These CMEs are flying into a void created by the earlier Cannibal CME. With little interplanetary material to slow them down, the storm clouds should reach Earth no later than July 31st, potentially intensifying any geomagnetic storm already underway. If the G3 forecast is correct, auroras will be visible at mid-latitudes across Europe and the USA on July 30-31.

'It's possible' the northern lights will be visible in far Northern California this week

The northern lights could appear in skies over the mid-latitudes — including in Washington, Oregon and far Northern California in the U.S. — at the start of this week due to a strong solar activity, according to the National Oceanic Atmospheric Administration’s Space Weather Prediction Center.

While the northern half of the U.S. could be treated to sightings of the aurora borealis in coming days, “it will be nothing like what we saw in May,” said Shawn Dahl, service coordinator for the Space Weather Prediction Center. In May, the aurora put on a rare celestial show with widespread sightings all the way into Southern California.

The northern lights most commonly light up skies over the farthest reaches of the globe near the North Pole, and people travel to places like Iceland and Greenland to see them, but they occasionally appear farther south than usual.


This week’s aurora forecast comes with bursts of material from the sun known as coronal mass ejections triggering a geomagnetic storm.

“Think of it as material from the sun and a strong magnetic field headed toward Earth, and when they arrive at Earth they can cause the geomagnetic storming,” Dahl said. There were also reports of solar flares, blasts of energy from the sun.

These geomagnetic storms drive the northern lights and are measured on a scale of G1 (minor) to G5 (severe). The Space Weather Prediction Center issued a geomagnetic storm watch forecasting G1-G3 conditions for July 29 to 31. Dahl said the West Coast is likely to see G1 geomagnetic storm conditions Monday night, a G3 early Tuesday morning and a G1 on Wednesday night. Early Tuesday morning starting at about midnight is likely to bring the highest possibility of seeing the aurora borealis in far Northern California.


“I would say it’s unlikely, but it’s possible,” he said. Dahl said the timing and the strength of the storms could change.

On the West Coast, the chances of the aurora appearing in Washington and northern Oregon are higher than in southern Oregon and Northern California, Dahl said.
