The faint partial halo CME first seen in the SOHO LASCO C2 field of view at 12:36 UT on June 09 had source region at about E165.  Since this was a back side event it will not arrive at the Earth.

No, radio dishes cannot broadcast galaxies. Although they can detect them, the above image features a photogenic superposition during a dark night in New Zealand about two weeks ago. As pictured above, the central part of our Milky Way Galaxy is seen rising to the east on the image left and arching high overhead. Beneath the Galactic arc and just above the horizon are the two brightest satellite galaxies of our Milky Way, with the Small Magellanic Cloud to the left and the Large Magellanic Cloud on the right. The radio dish is the Warkworth Satellite Station located just north of Auckland.

Rigel, also known by its Bayer designation Beta Orionis (β Ori, β Orionis), is the brightest star in the constellation Orion and theseventh brightest star in the night sky, with visual magnitude 0.12. The star as seen from Earth is actually a triple star system, with the primary star (Rigel A) a blue-white supergiant of absolute magnitude −7.84 and around 130,000 times as luminous as the Sun. An Alpha Cygni variable, it pulsates periodically. Visible in small telescopes, Rigel B is itself a spectroscopic binary system, consisting of two main sequence blue-white stars of spectral type B9.

Although Rigel has the Bayer designation “beta”, it is almost always brighter than Alpha Orionis (Betelgeuse). Since 1943, thespectrum of this star has served as one of the stable anchor points by which other stars are classified.
