''I have begun reading a bit more about these so-called noctilucent
clouds and the role they might play in sporadic-E. Fascinating
stuff. First observed after the huge Krakatoa volcanic eruption in
1883 in present-day Indonesia, it was originally thought they were
caused by volcanic debris spewed into the upper atmosphere. Now,
the more common theory is the debris that helps the clouds form is
dust from meteor showers. But I can't help but wonder, and
speculate, if the Sarychev Peak volcanic eruption in Russia a couple
weeks ago hasn't somehow contributed to this E-skip season by
dumping more debris in the atmosphere -- enough anyway for people
worldwide to report some very colorful sunsets recently. Just food
for thought''.
