About me
LIKES: astronomy, geology, history/archaeology, geography; travel, hiking, camping; photography, drawing/sketching, computer art; sci-fi (current fandom: Stargate SG1, former fandom: Star Wars); cats; children (because they're so much more sensible than adults).

DOESN'T LIKE: smoking, alchocolism, religious fanatism; pro-global warmers, child abusers, cat abusers, people who drive while using cell phones, politics, people who preach what they don't do themselves or know nothing about, people who stick their noses into areas out of their expertise; snow, fog, rain, ice.

Why I use Clipmarks
Mostly for quickly storing things fround on the Net.
The printing-what-you-want option is too cool and useful to miss, as well.
Don't have much time for *another* social-networking site, so I think I'll pass that up, for now at least. But you're welcome to drop me a note if you wish - as I like to say: my inbox is always open

POPSPersian Clouds - NLC's going south

 Spaceweather says: "Noctilucent clouds (NLCs) are supposed to be a high-latitude phenomenon, most often seen in Canada, Russia and northern Europe. On July 19th the electric-blue clouds crept south, all the way to Iran: "I took this picture from Mt. Sabalan, a 15,784 ft extinct volcano in northwestern Iran," says Siamak Sabet. "It is the third highest peak in our extremely mountainous country." When noctilucent clouds first appeared in the late 19th century, they were confined to latitudes above 50o N. Mt Salaban is located at 38o N, far below the old threshold. Just last week, NLCs were sighted in Turkey at 40o N and in recent years they have appeared at least as far south in the United States as Colorado and Utah, also around 40o N. Why are NLCs spreading south? That is an unsolved mystery of these puzzling clouds. Some researchers believe it is a telltale sign of climate change, but this remains controversial. One thing is certain: Sky watchers at all latitudes should be ale

 QUOTE: "There's a rainstorm underway on the sun's eastern limb. You'd better bring your asbestos umbrella, though, because the "droplets" are Texas-sized blobs of hot plasma. "This is prominence finery at its best," says photographer Pete Lawrence of Selsey, UK. "Small bright points within the prominence that were seen on the capture screen have been recorded as blurs due to the rapid motion of material in just a few seconds!" Prominences are clouds of hydrogen held above the surface of the sun by magnetic fields. While this particular cloud appears to be raining like a summer shower on Earth, the true situation is more complicated. Look carefully: Some of the plasma raindrops are falling "up." That's because the motions are controlled by not only gravity but also magnetism, a force of little importance in terrestrial rainstorms. The solar magnetic field is rooted below the sun's visible surface; roiling motions in the body of the sun itself cause magnetic fields high overhead t
