[astroCS] Quadrantidy

[Valer Romok]

Nedavno som nasiel pristup k zaujimavej databaze. Okrem ineho je tam
asi vyse 40 titulov periodik z astronomie, ale v anglictine. Kto by
chcel mat bezplatny pristup, nech sa mi ozve na mail, nie do
konferencie. Pristup je zatial len do konca tohto roka.

Meteors and Moons

A Nice but Short-Lived Shower

The annual Quadrantid meteor shower peaks around midnight on January
3/4. With New Moon on January 2, conditions couldn't be better, so
long as the local weather plays along. The shower is best viewed
before dawn when the radiant is highest for Northern Hemisphere
viewers, meaning this year North American observers will see the tail
end of the peak. Typical peaks can reach 100 meteors per hour if the
radiant lies directly overhead. With a lower radiant, atmospheric
extinction, and viewing a few hours past peak, observers might expect
up to 30 meteors per hour. The Quadrantids are named after a defunct
constellation, Quadrans Muralis, now part of northern Boötes.
