Huge Eruption on the Sun Creates 250,000-Mile-Long ‘Canyon of Fire’ https://petapixel.com/2025/07/16/huge-eruption-on-the-sun-creates-250000-mile-long-canyon-of-fire/ #solardynamicsobservatory #spaceweather #science #aurora #Space #News #NASA #cme #sun
Spectacular Solar eruption could cause auroras on Earth.
PetaPixelA relatively small but Earth directed Coronal Mass was emitted by the Sun at 1954Z 28Jun2024.
This NOAA simulation predicts it's arrival at about 0100Z on 2Jul2024. That's 1pm NZ time, but activity is predicted to last for about 18 hours.
Aurora may be observed at higher and lower latitudes.

Another X-Flare
June 19, 2025 @ 23:55 UTC
"X-Flare Alert. Sunspot region 4114 just produced an X1.9 solar flare peaking at 23:50 UTC (Jun 19). Coronal dimming is not yet evident meaning a noteworthy #CME is unlikely. More to follow whenever necessary."

“The G4 (Severe) geomagnetic storm watch remains in effect for tonight, June 1st…There are indications that the coronal mass ejection (CME) passage is weakening, but the solar wind conditions remain elevated, therefore additional periods of G3-G4 (Strong-Severe) levels remain possible. However, we now anticipate that conditions should weaken enough by tomorrow evening, June 2nd (EDT), that G1 (Minor) storm levels is the most likely peak response."

SEVERE GEOMAGNETIC STORM WATCH: A #CME is heading straight for Earth. NASA and NOAA models agree that it will strike Earth on June 1st. The impact could spark a severe (G4-class) geomagnetic storm with #aurora visible across Europe and many US states, including Connecticut. This won't be as big as the famous May 2024 storm, but it could be one of the bigger events of Solar Cycle 25 if a severe storm materializes. Check spaceweather.com for the latest.
An Earth directed Solar Flare has just been released from the Sun and it is a doozy! I will be keeping a close eye on Space Weather to give updates but I would expect auroras Sunday night/Monday morning!
Let's hope this offers similar views to Oct 10, 2024 or better!

Negative polarity CH HSS triggers G3 – Strong geomagnetic storm
A G3 – Strong geomagnetic storm was observed at 02:16 UTC on May 29, 2025, triggered by the arrival of a negative polarity coronal hole high-speed stream (CH HSS) at Earth. Coronal hole high-speed streams, and their associated transition zones called co-rotating interaction regions (CIRs), can create CME-like shock waves that are capable of producing strong geomagnetic disturbances and widespread auroras.
Potential Impacts: Area of impact primarily poleward of 50 degrees Geomagnetic Latitude.
Induced Currents - Power system voltage irregularities possible, false alarms may be triggered on some protection devices.
Spacecraft - Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur.
Navigation - Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur.
Radio - HF (high frequency) radio may be intermittent.
Aurora - Aurora may be seen as low as Pennsylvania to Iowa to Oregon. #geomagneticstorm #spaceweather #CME

In a real-life situation, the primary impacts would lead to serious disruptions in many sectors, including aviation, emergency response and health care, as hospitals would have to rely on back-up power generators for days.

Interested in cancer genetics? Don't want to fly somewhere to here about it? Next week the American Society of Human Genetics is having an online-only digital symposium on cancer genetics.

I think it's also worth up to 6 #CME credits if you do continuing medical education.

An X1.1 flare erupted from a new active region on the east limb, peaking at 15h20 UT 28 Mar (not 15h35 UT as previously stated).
After 1.5 hours the XRay flux is still above M-level, but is falling. The flare appears to be a filament eruption.
An R3 radio blackout affected the Caribbean, Central America and northern S America.
10cm, type II and type IV radio emissions and a coronal mass ejection were observed.
This flare marks the end of couple of fairly quiet weeks on the sun!
"G3 (Strong) Geomagnetic Storm Watch for 23 Mar" by NOAA Space Weather Prediction Center - The Sun erupted a coronal mass ejection (CME) expected to reach Earth on March 23 UTC at G3 storm level. That means forecasted Kp=7 for aurora down to Oregon, Idaho, Wyoming, Nebraska, Iowa, Illinois, Indiana, Ohio, Pennsylvania, New York and Massachusetts. https://www.spaceweather.gov/news/g3-strong-geomagnetic-storm-watch-23-mar #astronomy #aurora #AuroraBorealis #AuroraAustralis #CME #SpaceWeather
The nice thing about the expansion of diagnostic panels for respiratory pathogens is that even those who did not read the CDC EPIC study back in 2015 can now clearly appreciate the number of people who get to see the inside of a hospital/ICU from the sniffles "rhinovirus". #CME
