Sun online and solar activity 08.12.2014


INFO FROM SIDC – RWC BELGIUM 2014 Dec 07 12:33:18 The solar activity is rather low, and the strongest flare during last 24 hours was a C3.7 flare (peaked at 13:52 UT on December 6) which originated from the Catania sunspot group 24 (NOAA AR 2222). We expect C-class flares in the coming hours. An issolated M-class flare is possible from the Catania sunspot group 24 (NOAA AR 2222) which is currently situated close to the west solar limb (S20W70). The strong flaring activity originating from this active region might be accompanied with the proton event. Therefore, we maintain the warning conditions for a proton event. No Earth directed CMEs were observed during last 24 hours. The Earth is currently inside of a fast solar wind with the speed of about 690 km/s, and the interplanetary magnetic field magnitude is about 7nT. The fast solar wind originating from the large polar coronal hole with the extent to the low latitudes (up to about S40) arrived at the Earth yesterday, as expected. The concurrent slow increase of the solar wind speed, density and the interplanetary magnetic field which started early on December 6, indicate strong compression region in front of the fast flow. Decrease of density and strong increase of the solar wind speed and temperature (observed at about 16:00 UT on December 6), indicate arrival of the fast flow itself. The maximum solar wind speed of about 800 km/s was observed this morning. The highest value of the interplanetary magnetic field magnitude of about 25nT, was recorded at about 15:00 UT on December 6. Due to arrival of the fast flow we observed few intervals of negative value of the Bz component of the interplanetary magnetic field (down to -14 nT at about 18:30 UT on December 6), which induced active to minor storm geomagnetic conditions from about 18:00 UT on December 6 until early this morning (the local station at Dourbes and Izmiran reported values of K=4, and NOAA reported one interval of Kp=5). We expect unsettled to active geomagnetic conditions in the coming hours.

Andromeda Galaxy


The Andromeda Galaxy /ænˈdrɒmɨdə/ is a spiral galaxy approximately 2.5 million light-years (2.4×1019 km) from Earth in the Andromeda constellation. Also known as Messier 31, M31, or NGC 224, it is often referred to as the Great Andromeda Nebula in older texts. The Andromeda Galaxy is the nearest spiral galaxy to our Milky Way galaxy, but not the nearest galaxy overall. It gets its name from the area of the sky in which it appears, the constellation of Andromeda, which was named after the mythological princess Andromeda. The Andromeda Galaxy is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum Galaxy, and about 44 other smaller galaxies.
