The Sun online and Solar Activity 23.11.2014

UPH20141124091421 INFO FROM SIDC – RWC BELGIUM 2014 Nov 23 12:43:20 NOAA ARs 2209 and 2216 (Catania numbers 9 and 14 respectively) have delta-spots in their trailing parts and continue to produce C-class flares. However, the strongest flare of the past 24 hours was the C3.5 flare peaking at 10:53 UT today in the still unnumbered sunspot group that appeared from behind the east solar limb yesterday evening. We expect flaring activity on the C-level, possibly with an isolated M-class flare. A long filament in the northern hemisphere has finished crossing the solar central meridian, but its eruption may still lead to an Earth-directed CME.The Earth is currently inside a slow (around 400 km/s) solar wind flow with slightly elevated (7-8 nT) interplanetary magnetic field magnitude. Due to low solar wind speed, the geomagnetic conditions remained mostly at the quiet to unsettled level (K < 4), only with one interval of active conditions (K = 4) reported by IZMIRAN and NOAA yesterday evening. The geomagnetic conditions are expected to stay at the quiet to unsettled levels (K < 4), with isolated intervals of active conditions (K = 4).

Cassiopeia is a constellation in the northern sky, named after the vain queen Cassiopeia in Greek mythology, who boasted about her unrivalled beauty. Cassiopeia was one of the 48 constellations listed by the 2nd-century Greek astronomer Ptolemy, and it remains one of the 88 modern constellations today. It is easily recognizable due to its distinctive ‘M’ shape when in upper culmination but in higher northern locations when near lower culminations in spring and summer it has a ‘W’ shape, formed by five bright stars. It is bordered by Andromeda to the south, Perseus to the southeast, and Cepheus to the north. It is opposite the Big Dipper. In northern locations above 34ºN latitude it is visible year-round and in the (sub)tropics it can be seen at its clearest in from September to early November in its characteristic ‘M’ shape. Even in low southern latitudes below 25ºS is can be seen low in the North.
