I often see the sunspot data, but for some strange reason everyone just published the latest cycle so I can't see how this compares to previous ones.
I would like to quickly create a sunspot graph with sunspots per month in a format I could update using new data as it becomes available.
I've found a 5M file with masses of data on individual sunspots, but I would need to do an awful lot of work to make that usable and it must be available out there somewhere.
Can anyone tell me where.
PS. I tried searching this site, and internet.
The source for the official sunspotdata is the SIDC. They have daily, monthly and yearly data. sidc.oma.be/sunspot-data/ Note the caution when comparing sunspot cycles as formulated by Leif Svalgaard in previous threads.
I would also like to know why is it that everytime a new sunspot develops, it rotates from the non-facing side of the sun? Most of the new sunspots lately never develops on the earth facing side? Any reason for this?
