The Sun Online and solar activity. July 30, 2014

The largest event of the period was a C4 flare peaking at 16:33UT on 29 July in the trailing portion of NOAA 2130. This area shows some mixed magnetic polarities and was also the source of one C3 and three C1 flares. NOAA 2125 and 2127 contributed with a C1 flare each. NOAA 2126 has simplified and remained quiet. The long filament in the NE quadrant erupted early this morning between 04:30 and 05:30UT. According to the currently available STEREO-imagery, the associated CME was directed mostly to the north and away from Earth. Another CME was first observed by SOHO/LASCO at 01:25UT and was also associated to a filament eruption at or just behind the east limb. This CME is not directed to Earth. The filaments near the NE-limb and south near the Central Meridian (CM) were relatively stable. 
Further C-class flaring is expected, with a small chance for an M-class flare from NOAA 2127 and 2130. Solar wind speed declined further from 350 to 310 km/s, with Bz varying between -5 and +3 nT. A small equatorial hole is approaching the CM and may influence the geomagnetic field around 4 August.
Geomagnetic conditions were quiet and are expected to remain so.

M31: The Andromeda Galaxy

 Andromeda is the nearest major galaxy to our own Milky Way Galaxy. Our Galaxy is thought to look much like Andromeda. Together these two galaxies dominate the Local Group of galaxies. The diffuse light from Andromeda is caused by the hundreds of billions of stars that compose it. The several distinct stars that surround Andromeda’s image are actually stars in our Galaxy that are well in front of the background object.Andromeda is frequently referred to as M31 since it is the 31st object on Messier’s list of diffuse sky objects. M31 is so distant it takes about two million years for light to reach us from there. Although visible without aid, the above image of M31 was taken with a standard camera through a small telescope. Much about M31 remains unknown, including how it acquired its unusual double-peaked center.

M 78 in Orion

The nebula Messier 78 (also known as M 78 or NGC 2068) is a reflection nebula in the constellation Orion. It was discovered by Pierre Méchain in 1780 and included by Charles Messier in his catalog of comet-like objects that same year.

M78 is the brightest diffuse reflection nebula of a group of nebulae that include NGC 2064, NGC 2067 and NGC 2071. This group belongs to the Orion Molecular Cloud Complex and is about 1,600 light years distant from Earth. M78 is easily found in small telescopes as a hazy patch and involves two stars of 10th magnitude. These two stars, HD 38563A and HD 38563B, are responsible for making the cloud of dust in M78 visible by reflecting their light.

About 45 variable stars of the T Tauri type, young stars still in the process of formation as well as some 17 Herbig–Haro objects are known in M78.
