I am now in the third week of my annual February birthday fund-raising drive. The first two weeks were good, but not record-setting.

 

There are still two weeks left in this campaign however. If you have been a regular reader and a fan of my work and have not yet donated or subscribed, please consider doing so. I take no ads, I keep the website clean from pop-ups and annoying demands (most of the time). Thus, I depend entirely on my readers to support me. Though this means I am sacrificing some income, it also means that I remain entirely independent from outside pressure. By depending solely on donations and subscriptions from my readers, no one can threaten me with censorship. You don't like what I write, you can simply go elsewhere.

 

You can support me either by giving a one-time contribution or a regular subscription. There are five ways of doing so:

 

1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.

 

2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
 

3. A Paypal Donation:

4. A Paypal subscription:


5. Donate by check, payable to Robert Zimmerman and mailed to

Major solar flare from the Sun

X-1 solar flare
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.

Genesis cover

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 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.
