[net.space] why observe solar eclipses

I must concurr with Don Lynn on the reasons for observing solar eclipses.

Perhaps the most important reason is number 2, whereby we hope to determine
if the diameter of the solar photosphere is changing.  This has important
implications for our understanding of the solar power source. (ie, why
are we not detecting the predicted number of nutrinos?)  Also there is some
info from solar Max (the satellite) that indicates that the solar constant
(the amount of solar radiation recieved AT EARTH at all wavelengths) is
decreasing.  Although the data only covers a few years this is still an
important problem.  Accurate measurements of the size of the solar
photosphere could (bad pun) shed some light on the situation.

Finally, I cannot stress enough the sheer pleasure of being in the
central path of the eclipse.  Although I have watched totals before I still
packed my family and drove to North Carolina to see this one.  Although
we made the edge of the cloads with only 30 minutes to spare, and my
wife thought I was completely nuts, we were successful.  She then
exclaimed that it was worth the trip after all.   Like zen, a solar eclipse
MUST be experienced to understand the reasons for going.
