Beautiful Sol

I cannot resist posting this beautiful image from NASA, courtesy of Space Weather:

You can view such images terrestially with a portable H-alpha setup (singlet refractor + H-alpha filter). Below are some pics of APO (apochromatic) refractors (triplet refractor, corrected for 3 wavelengths + H-alpha filter):

APO setup 1
portable setup

You can tune the H-alpha filters to see prominences or surface-detail (granulation, sunsports, & "dark ribbons"). I have such a system for my 5" APO refractor, it works at f/20. The mfr built one for the Space Shuttle, & a local amateur has a similar one.

The NASA picture is a composite of 2 wavelengths: surface-detail & prominences.

Your vision of Category Theory Inst, should have real-world "cafe" like a mini solar observatory, observatory (1-meter class telescope), access to mountain air flights, etc. To stimulate the "theoretical minds" with real-world data.

Yes, Chimpanzee, Tekapo would be a good location for the Institute.

Hi Kea,

Think of all those neutrinos emanating from the sun.

The Earth is flowing throw this neutrino "ocean".

Some neutrinos are flowing through the Earth, occasionally perturbing atoms on a stochastic basis.
