About that Giant Planet Possibly Hiding in the Outer Solar System…by NANCY ATKINSON on FEBRUARY 16, 2011

An article this week in The Independent suggested the new planet, called Tyche, had already been found among data from the WISE mission. This prompted the WISE team to post a rebuttal on their Facebook page: “Not true. A pair of scientists published a paper stating that if such a big planet exists in the far reaches of the Solar System, then WISE should have seen it. That is true. But, analysis over the next couple of years will be needed to determine if WISE has actually detected such a world or not.”
To make sense of this all, Universe Today sought out a scientist who has looked at the outer solar system as much as anyone, if not more: Mike Brown, of Eris, Haumea and Makemake fame – to get his take on Tyche.

New Solar Flare
fr/spaceweather.com
MAJOR FLARE: Earth-orbiting satellites have detected the strongest solar flare in more than four years. At 0156 UT on Feb. 15th, giant sunspot 1158 unleashed an X2-class eruption. X-flares are the strongest type of x-ray flare, and this is the first such eruption of new Solar Cycle 24. The explosion that produced the flare also sent a solar tsunami rippling through the sun’s atmosphere and, more importantly, hurled a coronal mass ejection toward Earth. This raises the possibility of geomagnetic storms in the days ahead. Visit http://spaceweather.com for images and updates.

New Solar Flare
EARTH-DIRECTED SOLAR FLARE: On Feb. 13th at 1738 UT, sunspot 1158 unleashed the strongest solar flare of the year so far, an M6.6-category blast. NASA’s Solar Dynamics Observatory recorded an intense flash of extreme ultraviolet radiation, circled below:
The eruption produced a loud blast of radio waves heard in shortwave receivers around the dayside of our planet. In New Mexico, amateur radio astronomer Thomas Ashcraft recorded these sounds at 19 to 21 MHz. “This was some of the strongest radio bursting of the new solar cycle,” he says. “What a great solar day.”

Sun’s Plasma Bullets
DODGING PLASMA BULLETS: The remains of old sunspot complex 1147-1149 are rotating over the eastern limb today. Although the region is in an advanced state of decay, it’s not dead yet. During the late hours of Feb. 11th, a plasma bullet came rocketing out of the region’s unstable core. Watch the movie–but don’t blink, because it’s fast (21 MB Quicktime):

The eruption was not geoeffective. Earth’s magnetic field will remain undisturbed as the ‘bullet’ sails wide-left of our planet over the weekend.
This region has been spitting plasma and crackling with flares since it first emerged more than a month ago on Jan. 10th. Remarkably, however, every eruption so far has missed Earth. Why? It’s just luck: Most of the blasts occurred while AR1147-1149 was on the far side of the sun. Statistically speaking, a plasma bullet in our direction may be overdue

ASTEROID FLYBY: Newly-discovered asteroid 2011 CA7 is going to fly past Earth on Feb. 9th only 63,000 miles away, or 1/4th the distance to the Moon. At closest approach around 1700 UT, the VW-Bug-sized space rock will zip through the constellation Orion glowing like a 17th magnitude star. [
