''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''.
