A blank sun during solar maximum
Though it is not yet official, it appears the sun is blank of sunspots today, for the first time since January 16.
Solar scientists have concluded that the solar minimum of the past four years has ended and that the sun is now moving towards solar maximum. The recent activity in August has seemed to confirm this. However, once the minimum has ended, the sun should not have any further blank days until the maximum is over and the sun is ramping back down to solar minimum. That the sun should appear blank again during its ramp up to solar maximum is quite unusual, probably unprecedented, and is further evidence that the sun is heading towards a period of little or no solar activity.
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
