http://physicsworld.com/cws/article/news/2015/aug/07/new-sunspot-analysis-shows-rising-global-temperatures-not-linked-to-solar-activity says

A recalibration of data describing the number of sunspots and groups of sunspots on the surface of the Sun shows that there is no significant long-term upward trend in solar activity since 1700, contrary to what was previously thought

and so on William M. Connolley (talk) 08:33, 17 August 2015 (UTC)

Cut-n-paste[edit]

The article currently contains (literally) "The current solar cycle began on January 4, 2008, with minimal activity until early 2010.[3][4] " - ie the [3[[4] aren't refs, they're just brackets. Presumably copied from somewhere else William M. Connolley (talk) 08:38, 17 August 2015 (UTC)

Was copied from Solar cycle 24, fixed the refs for the "brackets" as in that article. Vsmith (talk) 13:40, 17 August 2015 (UTC)

Page=211101[edit]

Does this article reference really have a page=211101?[1]

Need an updated "400 410? years of sunspot observations" graph[edit]

That graph is now ten years old. It's missing Solar Cycle 24, entirely. It really needs to be updated! Does anyone have a newer version? NCdave (talk) 11:14, 23 November 2015 (UTC)

Well, I went ahead and made an updated version of the graph, showing sunspot numbers through Oct., 2015. I.e., I added another decade to the graph.
I started with the previous version which was uploaded in 2006. I pasted a properly-scaled version of http://services.swpc.noaa.gov/images/solar-cycle-sunspot-number.gif (last updated 2015-11-09) onto the end of the graph, to bring it up to date. The colors don't match (the new part is more purple than blue), and I didn't extend the black smoothed trend line, but at least it doesn't omit Solar Cycle 24 anymore.
I didn't bother to change the caption -- it still says "400 years" even though it is obviously slightly longer than that, now.
Strangely, the shrunk version in the article is still the old version. It doesn't show the additional decade. Will it get updated automatically, eventually, or do I need to do something else? NCdave (talk) 16:00, 23 November 2015 (UTC)
I see that the shrunk version in the article eventually updated to show the additional decade. NCdave (talk) 03:48, 5 December 2015 (UTC)
