GEOMAGNETIC UNREST: For the next two days, Earth will pass through a minor stream of solar wind flowing from a southern hole in the sun's atmosphere. Full-fledged geomagnetic storms are not expected. Nevertheless, Arctic sky watchers can expect to see auroras--some quite bright--as Earth's magnetic field responds to the buffeting action of gaseous material from the sun. http://spaceweather.com/ http://www.solarham.net/ https://services.swpc.noaa.gov/text/d... APRIL IS THE BEST MONTH FOR ZODIACAL LIGHTS: Tonight, when the sun does down and the glow of sunset fades away, another glow may take its place--the Zodiacal Light. It stretches upward from the western horizon forming a pale luminous triangle visible from places with exceptionally dark skies. When you see the Zodiacal Light, you've seen the backbone of our solar system. Zodiacal Light is sunlight reflected from interplanetary dust. The pale glow traces the dusty plane through which all planets orbit, known to astronomers as the ecliptic plane. April is a good month to see Zodiacal Light because the ecliptic plane juts over the evening horizon almost vertically. Because Zodiacal Light is faint, moonlight easily overwhelms it. Nights around the New Moon favor their visibility. With the next New Moon due on April 5th, now is a great time to look. http://spaceweather.com/archive.php?v... https://earthsky.org/tonight/zodiacal...
