Solar scientists at the Marshall Space Flight Center have once again adjusted their prediction for the upcoming solar maximum.
Solar scientists at the Marshall Space Flight Center have once again adjusted their prediction for the upcoming solar maximum.
The current prediction for Sunspot Cycle 24 gives a smoothed sunspot number maximum of about 70 in May of 2013. We are currently over two and a half years into Cycle 24. Five out of the last six months with average daily sunspot numbers above 40 has raised the predicted maximum above the 64.2 for the Cycle 14 maximum in 1907. This predicted size still make this the smallest sunspot cycle in over 100 years.
This new prediction is slightly higher than their prediction of 63 from two weeks ago. As they note, even this new number leaves us with a very weak 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 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

How little science actually knows! Good information. It’s been unusually cold in the Seattle area in the past few weeks — but that is regional weather. Hopefully we don;t get a weak maximum!
Did you notice the date on that latest forecast? My copy said September 1, 2011. I think they accidentally reposted the older one.
I sent an email to the webmaster for that page last night, and about 15 minutes ago got a message saying they would look into it. Now I see that page has disappeared, and it is a dead link.
Tad,
Good catch! I did not notice the incorrect date. The site is now available, and the prediction, dated today, now calls a sunspot maximum number of 59 in early 2013, lowering the prediction down slightly from two weeks ago but leaving the date of the peak the same.
Can they still call it a solar max, when the sun keeps declining?
;)
