Il n'y aura visiblement aucune influence sur la Terre ou la magnétosphère.

je coupe juste après celui là

mais il y a tellement à trasmettre lorsqu'on à décidé en son âme et conscience

ou un autre jour sur la route ...

toujours aussi écoeurants eux :

un peu d'espoirs mtnt :

Non, je ne suis pas allé voir. J'aime tomber sur des animaux morts, dans la nature, car c'est une confrontation directe avec cette mort qui nous attent tous. Mais je ne vais jamais volontairement
voir la mort. Question de principes.

Bon dimanche, néo. Tu peux envoyer tout ce que tu veux, ça ne me dérange pas et c'est de qualité.

Mon portable date de 1876.... Mais cela peut interesser des visiteurs, oui. Je vais le mettre dans les liens, merci.

What's up in space



RADIATION STORM: Accelerated by yesterday's X-flare, energetic protons from the sun are swarming around Earth on Jan. 28th. The
radiation storm ranks S2 on NOAA scales, which means this is not a severe storm. Nevertheless, it can
still affect spacecraft and satellites at the nuisance level. For instance, this
coronagraph image from SOHO is clouded by protons hitting SOHO's onboard digital camera.

ANNULAR SOLAR ECLIPSE: A "ring of fire" solar eclipse is coming to the USA this spring. It's the first annular eclipse visible from
the contiguous United States in almost 18 years. Science@NASA has the full story and a

X-FLARE (UPDATED): Departing sunspot 1402 unleashed an X2-class solar flare on Jan. 27th at 18:37 UT. NASA's Solar Dynamics Observatory recorded
the extreme ultraviolet flash:

Sunspot 1402 is rotating onto the far side of the sun, so the blast site was not facing Earth. Nevertheless, energetic protons accelerated by the blast are now surrounding our planet,
and an S2-class radiation storm is in

The explosion also produced a spectacular coronal mass ejection (CME). A movie
from the Solar and Heliospheric Observatory shows the cloud racing away from the
sun at 2500 km/s or 5.6 million mph. Update: Work by analysts at the Goddard Space Weather Lab shows that the CME will just miss Earth when its edge passes by our
planet on Jan. 30-31. Click to view an animated forecast track:

The cloud will deliver a glancing blow to Mars on Feb 1st and a nearly-direct hit to NASA's STEREO-Ahead spacecraft on Jan. 29th.  Solar flare alerts: text, voice.

AURORAS OVER THE USA: The geomagnetic storm of Jan. 24th died out before night fell over North America--or did it? According to
reports still trickling in, auroras were reported not only in Canada, but also in some of the lower 48 US states. Shawn Malone of Marquette, Michigan, took this picture looking north
from the shores of Lake Superior:

"I got to view a slice of the aurora through a tiny opening in an otherwise completely overcast sky," says Malone. "It appeared to be a pretty decent display."

Prompted by the CME warning, Mike Hollingshead of Nebraska drove 450 miles to the Badlands National Park of South Dakota hoping to catch a glimpse of the auroras. He got more than he
bargained for: "While I waited for some sign of auroras, the most amazing
fireball I've ever seen blasts down. It flashed brightly and illuminated the terrain around me." Later, the auroras made a belated appearance, turning the badland sky green.

More auroras could be in the offing. A solar wind stream is heading for Earth, due to arrive on Jan. 28-29. NOAA forecasters estimate a 15% chance of geomagnetic storms at high
latitudes. Aurora alerts: text, voice.
