Livingston and Penn Data UPdated to early 2011

13 Apr

I found this in some later reading. It looks as though the sun spot data is tracking pretty well.

    Where did you get the graph from? Was it a website, or a publication? A URL would help a lot to get more of the background to it.

    I have been following the paper that Livingston and Penn wrote some time ago about the potential for vanishing sunspots. As sort of an amateur climatologist I was very interested in what they wrote. I saw the original paper and then another update from them (I think last year). Can someone help us amateur’s understand what the graphs mean? It looks like the intensity continues to rise and the magnetic strenght is continuing to fall. It also looks like the 1500 gauss limit will be reached a bit after 2015 now (based on linear extrapolation). Is this a correct assumption?
