Heh, and here I thought band conditions were poor yesterday...

Protip: a coronal mass ejection is not only an event after you've consumed too many Mexican lagers.

#CME incoming, possibility of #aurora

Predicted arrival time around 15Apr2025 1800 GMT, so 6am 16Apr NZ time. Not so good for NZ, perhaps better further West where it will be longer until daybreak..

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!

A Carrington Level Event today would pretty much plunge the entire planet into full auto-destruct mode.

A Coronal Mass Ejection from the Sun is predicted to impact Earth within the next hour.

Sadly it is daylight and cloudy here but you Northern hemisphere folks may have better luck.

"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

While another solar wind stream is heading for Earth today, a solar storm last year demonstrated that even smaller solar events are something to worry about. The Gannon storm in May was formed when dozens of solar flares sent at least five coronal mass ejections (CMEs) toward Earth. Those CMEs merged creating a major event. Researchers estimate the Gannon storm caused at least $500 million in losses for farmers alone. https://spacenews.com/solar-flares-in-may-2024-revealed-earths-vulnerability-to-space-weather/

STRONG GEOMAGNETIC STORM PREDICTED: Two CMEs are heading for Earth, due to arrive on Dec. 31-Jan. 1. The one-two punch to Earth's magnetic field could spark a strong G3-class geomagnetic storm with mid-latitude auroras in the USA and Europe. Full story @ Spaceweather.com

AN X-CLASS DOUBLE SOLAR FLARE: Solar activity remains high with an X-class double solar flare on Oct. 26th. The explosion hurled an impressive CME into space, and it appears to have an Earth-directed component. Several big sunspots are turning toward Earth, so this could be the beginning of a week of stormy space weather. Also, a CME grazed Earth today, 10/26. The impact was weak, barely increasing solar wind speeds near Earth. High-latitude auroras are possible tonight. Spaceweather.com

October 24, 2024 @ 04:25 UTC (UPDATED)

"A returning sunspot region now reassigned AR 3869 just produced a strong X3.3 solar flare at 03:57 UTC (Oct 24). A type II radio emission with an estimated velocity of 610 km/s was recorded. This event will be associated with a coronal mass ejection (#CME) based on dimming following the event. Because the flare location is located off the east limb, it will be directed mostly away from Earth. A further update will be provided once coronagraph imagery is updated.

"CME Update #2: Despite the X3.3 solar flare being located close to the southeast limb, the resulting halo coronal mass ejection (CME) appears to be wide enough to include an Earth directed component. If so, a passage past our planet will be possible within 48-72 hours. A further update will be provided later today once an official tracking model is available.

"A minor (G1) geomagnetic storm watch was officially added for Saturday, October 26th. The edge of the X3.3/Halo CME is expected to deliver a glancing blow to our geomagnetic field. A prolonged period of southward Bz following a potential passage could increase the chances of storming and visible #aurora at higher latitudes. Stay tuned this weekend for further updates."

LARGE SUNSPOTS ARE TURNING TOWARD EARTH: An impressive group of large sunspots is emerging over the sun's southeastern limb. Emerging sunspot AR3869 erupted this morning producing a slow X3.3-class solar flare. This explosion almost certainly produced a CME and it's yet to be determined if this could fire up aurora on Earth in the coming days. https://www.Spaceweather.com
