I've just written a blog post over on Solar Stormwatch. It can be found at http://blogs.zooniverse.org/solarstormwatch/2012/06/sunspots-ahoy/ . There you can see a comparison between the  observations and photographs of the sunspots and find out about the resulting disturbances at the Earth. It really is a remarkably accurate record, thanks for bringing it to our attention! :)

Chris,

Caro

The similarity between Hilary's log keeper's little drawing and the photo are amazing  8)

Wow, never guessed that one mention of the forum would lead to such an interesting and details followup.

My thanks  to everyone - it's made my day!

Just to say the sunspot story gets a mention on the recycled electron's podcast: The People Inside Lintott. :D

And just when you thought the story was over.... We are in the middle of a big tidy up and I came across an old book from the 1940s called "The Earth's Wonders."  It includes a section on wonders of the solar system (though slightly more low key than Prof Cox's version!) This is a page from a section on the Sun showing the February 1917 sunspots!



Just had to let you know! :)

On 6th December 1915 Andes recorded 'very brilliant northern lights' at 5pm - they're on Northern Patrol, and midday position 64 46 N 12 58 W

And the following day, at 10pm they record 'bright northern lights'.

Which must mean that there were lots of sunspots around...and here they are!  I love it when the 'dots join up':
http://adsabs.harvard.edu/full/1917Obs....40..293M (look on the left for page 294 because this mentions 23 sunspots, and Group 7624 on page 295.... whew!)

At 2.30 there was a moderate display of the aurora borealis which lasted about 10 minutes and was under the constellation Cassiopea.
