Major solar flare from the Sun
The flare is the bright spot, center bottom. Click for original image.
The Sun today unleashed an X1-class solar flare, one of the more powerful seen since the ramp up to solar maximum began at the start of 2020.
More information here, with this quote:
The blast also hurled a CME [coronal mass ejection] into space. Coronagraph images are not yet available, but evidence for a CME is already pursuasive [sic]. The USAF reports strong Type II and Type IV radio emissions generated by a CME plowing through the sun’s atmosphere. In addition, energetic particles accelerated at the leading edge of a CME have already reached Earth.
When will the CME itself arrive? Assuming that it is Earth directed, probably on Oct. 30th or 31st. Fresh data from SOHO coronagraphs will allow a more precise forecast, so stay tuned.
During the flare, a pulse of X-rays and extreme UV radiation ionized the top of Earth’s atmosphere, causing a strong shortwave radio blackout centered on South America:
Aviators, mariners, and ham radio operators on the daylit side of Earth may have noticed strange propagation effects at frequencies below 30 MHz.
While this flare is unlikely to cause any significant disturbances to orbiting or Earth-based technology, the flare was emitted by a large sunspot that is still active, can still flare again, and is well positioned on the Sun to send more material and radiation Earthward.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

The propagation conditions are great! I am working Europe, Argentina, and African stations on the ten meter band, which I have not been able to do in years because of the minimum.
