Hi,

Having got the info from a fellow astronomer about this Japanese Woman who was a great Sun sketcher in her life.

Interesting, Rainer. Looks like she produced lots of good data over her lifetime.

It would be nice if her entire sketch database could be found somewhere. I have numerous white light observations compiled in the 1980s, early 1990s that I could match up against them.

Hi James,

I made some homework and searched a lot but nowhere so far is the collection available. Not even in the Museum where they are stored.

Must be a case of " National Security " as a guy I know called past POTUS of USA used to decide :lol: :lol: :lol: :lol: :lol:
