I don't know, but according to my _1995 Information Please Almanac_: "The
temperature at the core of our Sun must be 20 million degrees centigrade, the
surface temperature averages 6,000 degrees centigrade, or about 11,000
degrees Fahrenheit."
I won't put us past having created a tiny region of 60 million degrees
centigrade for some fraction of a second -- hardly anything surprises me
any more -- but Yoicks!
