The Sun Online and solar activity. February 10, 2014

The solar flaring activity is decreasing in last few days. During the past 24 hours four C-class flares and an isolated M class flare were observed. The M1.0 flare which peaked at 16:00 UT on February 9, originated in the active region right behind the east-south-east solar limb. It was accompanied by coronal dimmings, an EIT wave, an erupting prominence and a post-eruption arcade. The associated full halo CME was first seen in the SOHO LASCO C2 field of view at 16:00 UT on February 9. Due to the source region position, we do not expect this CME to arrive at the Earth. From the currently available data, the prominence eruption (in the north-east quadrant of the Sun) observed at about 05:30 UT on February 10 does not seem to be associated with the Earth directed CME. Three out of seven,
currently numbered sunspot groups visible on the solar disc, have beta-gamma configurations of the photospheric magnetic field, and still growing. Catania sunspot groups 27 and 28 (NOAA ARs 1968 and 1967 respectively) have rotated behind the west solar limb. Due to the close to the solar limb position of these groups we still keep warning conditions for a proton event. We expect flaring activity on the C-level, with the possibility of an isolated M-class flare.The solar wind speed is currently around 460 km/s, and the interplanetary magnetic field magnitude is stable amounting about 5-6 nT. We expect quiet to unsettled (K<4) geomagnetic conditions in the coming hours.

Falling to Earth

What would it be like to fall to Earth from really high up? A new record for the highest jump was accomplished in 2012 by Felix Baumgartner. Surpassing the previous record of 31.3 kilometer plummet, Baumgartner, in a commercial venture, jumped off a floating balloon platform 39.0 kilometers above New Mexico, USA and had his entire fall recorded on video. Baumgartner wore a pressurized suit able to provide breathable air and warmth while up in the balloon, but then cooling from the heat generated by the friction if his fall. Free falling 36.4 km before deploying his parachute, Baumgartner surpassed 1,000 km per hour and thesound barrier during the descent. The above video records his four minutes and 19 seconds of free fall in real time. The stunt included a somewhat unexpected but potentially dangerous spin that occurred during the second minute which could have knocked out or disoriented Baumgartner. After an enthralling plummet, Baumgartner’s parachutes deployed and he landed safely.

IC443 The Jelly Fish Nebula

IC 443
 (also known as the Jellyfish Nebula and Sharpless 248 (Sh2-248)) is a Galactic supernova remnant (SNR) in the constellation Gemini. On the plan of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth.

IC 443 may be the remains of a supernova that occurred 3,000 – 30,000 years ago. The same supernova event likely created the neutron star CXOU J061705.3+222127, the collapsed remnant of the stellar core. IC 443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.
