Prachtig
Wil je ze hier ook nog inzetten misschien?

Adembenemend Noorderlicht #2

Done!
Zijn inderdaad echt prachtige foto's.

Zware uitbarsting zojuist, X1.4 richting de aarde.

X-FLARE! Big sunspot AR1520 unleashed an X1.4-class solar flare on July 12th at 1653 UT. Because the sunspot was directly facing Earth at the time of the blast, this is a geoeffective event. Stay tuned for updates about possible CMEs and radio blackouts.

NASA's Solar Dynamics Observatory recorded a flash of extreme ultraviolet radiation from the blast site:



The UV and X-ray pulse from the flare will have partially ionized Earth's upper atmosphere on the dayside of our planet, disturbing the normal propagation of radio signals. Watch the Realtime Space Weather Gallery for possible reports of sudden ionospheric disturbances and other effects.

NOCTILUCENT CLOUDS: This morning a vast bank of electric-blue noctilucent clouds rippled across northern Europe. "It was like water in the sky," says Barbara Grudzinska, who photographed the display from Warsaw, Poland:



"These are the first noctilucent clouds this year so clearly visible at our latitude in Warsaw (52 N)," says Grudzinska.

When NLCs first appeared in the 19th century, the mysterious clouds were confined to the Arctic, most often seen in the same places as Northern Lights. In recent years, however, their "habitat" has been expanding, rippling as far south as Colorado, Virginia, Kansas, and Utah. (Here are some examples of sightings in the lower United States.) There is growing evidence that the expansion is a sign of climate change, although this remains controversial.

Whatever the reason, noctilucent clouds aren't just at high latitudes anymore, so sky watchers everywhere should be alert for them. Observing tips: Look west 30 to 60 minutes after sunset when the sun has dipped 6o to 16o below the horizon. If you see luminous blue-white tendrils spreading across the sky, you've probably spotted a noctilucent cloud.

14 juli misschien poollicht

Klopt, morgen zeker even in de gaten houden.

Jammer dat het weer zo verrot is hier, zal wel veel bewolking hangen

REVISED FORECAST: The CME launched toward Earth by yesterday's X-flare is moving faster than originally thought. Analysts at the Goddard Space Weather Lab have revised their forecast accordingly, advancing the cloud's expected arrival time to 09:17 UT (5:17 am EDT) on Saturday, July 14th. Weekend auroras are likely.

De X-flare bereikt de aarde dus eerder .

Impact vindt plaats rond 10:15 Nederlandse tjd.
15% kans op een "severe impact" in de Mid-latitutes (Nederland).
Stekkers dus uit het stopcontact halen!!

10:15? Dat is vanavond neem ik aan? En ik geloof dat stekkers eruit weinig helpt bij een impact als deze.
