Laffen Jensen wrote on New Year’s Eve: “Pearl Clouds (polar stratospheric clouds) have been observed since several days after Christmas, over large parts of Norway. The clouds have been large and covered partially large parts of the sky.”
The Orionid meteor shower will rain bits of Halley's Comet on Earth tonight in a promising weekend "shooting star" display. You can even watch the celestial fireworks online if bad weather spoils your local view. CREDIT: Brad Goldpaint/Goldpaint Photography View full size image
From the Northern Hemisphere, you can see a smattering of Perseid meteors in the evening hours. The meteors tend to be few and far between at mid-evening, though this presents the best time of night to try to catch an earthgrazer – an elongated, long-lasting meteor that travels horizontally across the sky. Earthgrazers are rare but most memorable if you’re lucky enough to spot one.
