INFO FROM SIDC – RWC BELGIUM 2014 Dec 09 12:23:44 Solar activity has slightly increased with several C-class flares, originating from NOAA active region 2230. The strongest flares were C8.1 and C8.6 flares, probably not accompanied by a CME. NOAA 2230 has a beta configuration of it’s photospheric magnetic field and it’s trailing part has grown in size. No Earth directed CMEs were observed. Flares at the C-level are expected, with an increased chance for M-flares (30% probability).The solar wind speed reached high values (up to 700 km/s) during the first half of the period and then decreased to current values near 530 km/s. The magnitude of the interplanetary magnetic field is stable around 5 nT. A few time slots of active conditions were reached (to 4 for local K at Dourbes and estimated NOAA Kp). Quiet to unsettled magnetic conditions are expected.

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.
