The Sun Online and solar activity. March 01, 2013

The strongest flare in the past 24 hours was a C8.1 flare from NOAA AR1982-Cat46, now on the solar west limb. Several active regions contain the potential for M or even X-class flares. The proton flux levels remain
above event threshold, since mid Feb 25 already for 4 days in a row.Quiet geomagnetic conditions are expected in the coming days.

NGC 7331 and Beyond

Big, beautiful spiral galaxy NGC 7331 is often touted as an analog to our own Milky Way. About 50 million light-years distant in the northern constellation Pegasus, NGC 7331 was recognized early on as a spiral nebula and is actually one of the brighter galaxies not included in Charles Messier’s famous 18th century catalog. Since the galaxy’s disk is inclined to our line-of-sight, long telescopic exposures often result in an image that evokes a strong sense of depth. The effect is further enhanced in this sharp image by galaxies that lie beyond the gorgeous island universe. The background galaxies are about one tenth the apparent size of NGC 7331 and so lie roughly ten times farther away. Their close alignment on the sky with NGC 7331 occurs just by chance. Seen here through faint foreground dust clouds lingering above the plane of Milky Way, this visual grouping of galaxies is also known as the Deer Lick Group.


Winter Triangle

A bright asterism of the northern winter sky Winter Triangle  (part of Winter hexagon) . Its corners are the three 1st-magnitude stars Betelgeuse (α Ori), Procyon (α CMi), and Sirius (α CMa).

These three stars are three of the ten brightest objects, as viewed from Earth, outside the Solar System. Betelgeuse is also particularly easy to locate, being a shoulder of Orion, which assists stargazers in finding the triangle. Once the triangle is located, the larger hexagon may then be found.

Several of the stars in the hexagon may also be found independently of one another by following various lines traced through various stars in Orion.

The stars in the hexagon are parts of six constellations. Counter-clockwise around the hexagon, starting with Rigel, these are Orion, Taurus, Auriga,Gemini, Canis Minor, and Canis Major.
