Salut mo cher Damien,


Hey, ton cousin du Québec. Mon cher il y a du mouvement au parc Yellowstone !!!


http://www.seis.utah.edu/req2webdir/recenteqs/Maps/Yellowstone.html


Prends bien soins de toi, Depuis des mois, voir des années et je t'ai deja vu en meilleur forme. Tu garde la forme ?????


Chatruner ton ami du Qc.


+ 6 hres avec moi, donc.... bonne nuit.

Salut cousin. J'ai vu mieux en effet, comme j'ai déjà vu le Yellowstone bouger... Mais la roue tourne, ne t'inquiète pas. Bon courage, l'ihver a du mal à finir chez vous.

CHANCE OF STORMS: NOAA forecasters estimate a 35% to 60% chance of polar geomagnetic storms on April 1-2 when at least three CMEs are
expected to deliver glancing blows to Earth's magnetic field. The best-guess forecast calls for minor G1-class
storms. High-latitude sky watchers should be alert for auroras. Aurora alerts: text, voice


IMPULSIVE SOLAR FLARE SCRAMBLES RADIO SIGNALS: On Saturday, March 29th, the magnetic canopy of sunspot AR2017 erupted, producing a brief but
intense X1-class solar flare. A flash of extreme UV radiation sent waves of ionization
rippling through Earth's upper atmosphere and disturbed the normal propagation of terrestrial radio transmissions. Radio engineer Stan Nelson of Roswell, NM, was monitoring WWV at 20 MHz when the
signal wobbled then disappeared entirely for several minutes:





"The Doppler shift of the WWV signal (the 'wobble' just before the blackout) was nearly 12 Hz, the most I have ever seen," says Nelson.


The flare not only blacked out radio signals, but also produced some radio signals of its own. The explosion above sunspot AR2017 sent shock waves racing through the sun's atmosphere at
speeds as high as 4800 km/s (11 million mph). Radio emissions stimulated by those shocks crossed the 93 million mile divide to Earth, causing shortwave radio receivers to roar with static. Here
is a plot of the outburst detected by Nelson using a 20.1 MHz RadioJove receiver. Elsewhere, strong bursts were recorded at frequencies as high as 2800 MHz. It was a very broad band event.


NASA's Solar Dynamics Observatory recorded a beautiful movie of the flare:





The flash you just saw was extreme UV radiation, the type of radiation that ionizes the upper layers of our atmosphere. In this case, the ionizing action of the flare led to a rare magnetic crochet, measuring 17 nT at the magnetometer in Boulder, Colorado.


A magnetic crochet is a ripple in Earth's magnetic field caused by electrical currents flowing in air 60 km to 100 km above our heads. Unlike geomagnetic disturbances that arrive with CMEs days
after a flare, a magnetic crochet occurs while the flare is in progress. They tend to occur during fast impulsive flares like this one.


The magnetic field of sunspot AR2017 is decaying now, but it still poses a threat for eruptions. NOAA forecasters estimate a 55% chance of M-class flares and a 20% chance of X-class flares on March 31st. Solar flare alerts: text, voice

OPPOSITION OF MARS: Earth and Mars are converging for a close encounter in April. It's only March, but the view through backyard telescopes
is already superb. Michael A. Phillips of Swift Creek, NC, took this picture using a 14-inch telescope on March 27:





In Phillips's picture, south is up. It shows the rapidly evaporating North Polar Cap (summer arrived in February), orographic clouds over martian volcanoes near the equator, and a bright blue
cloud filling Hellas Basin in the south. Only an experienced astrophotographer can produce this kind of Hubblesque detail using backyard optics. Novice observers looking through the eyepiece of a
small telescope can still see a lot, however, including the rusty-red disk of Mars and bright smudges corresponding to the polar cap and Hellas Basin.


The view will improve in April. Get ready to see the Red Planet at its best as explained in "The Opposition
of Mars" from Science@NASA.

All Sky Fireball Network














Every night, a network of NASA all-sky cameras scans the skies above the United States for meteoritic fireballs. Automated software maintained by
NASA's Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth's atmosphere and many other characteristics. Daily results are presented here on
Spaceweather.com.


On Mar. 30, 2014, the network reported 3 fireballs.
(3 sporadics)





In this diagram of the inner solar system, all of the fireball orbits intersect at a single point--Earth. The orbits are color-coded by velocity, from slow (red) to fast (blue). [Larger image] [movies]
