Warwick Hughes on the second solar max. It was looking like were going to have a double hump in the Sunspot numbers, but here are the results:
My page [Hughes] a month ago. From here it looks like a slide towards the next solar minimum
– NASA/NOAA say in this chart it will not be before ~2020.
An earlier minimum would not amaze me.
I find it interesting that Solar Cycle 24 is following so closely with Solar Cycle 5, which resulting in the Dalton Minimum. The question remains, are we on the cusp of the next grand minimum?
