The very slow ramp up to maximum
As it does every month, NOAA’s Space Weather Prediction Center released today its monthly updated graph of the Sun’s solar cycle sunspot activity. I have posted the July graph below.
For the first time in four months there was a increase in sunspot activity, albeit small. The sun has been even more active in August, as shown by the flurry of sunspots on its face from August 1 (shown on the left) and the August 8 solar flare, the most powerful produced in four years.
This monthly graph, however, continues to suggest that the next solar maximum will be very very weak, even weaker than the most up-to-date predictions for the next solar maximum.
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. from any other book seller, or direct from my ebook publisher, ebookit. 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
