Five C flares and three M flares were measured by GOES during the past 24 hours. The strongest flare was an M1.3 flare with a peak time on January 4 at 10:25 UTC. NOAA AR 1944 was responsible for most of the flaring activity. NOAA AR 1944 has shown some growth in size and number of sunspots. NOAA AR 1937 has also grown and produced one C4.0 flare peaking on January 3 at 18:35 UTC.
The chances for C flares are high (90%). Also more M flares are possible (probability 50%), especially from NOAA AR 1944. There is a slight chance for an X flare (15%). We maintain the warning condition for proton events. No Earth-directed CMEs were observed.Solar wind speed measured by ACE varied from 450 to 550 km/s. The magnitude of the interplanetary magnetic field is stable around 4 to 6 nT, with a fluctuating Bz- component varying between -6 and +5 nT. No signatures of any ICME arrival
has been detected yet. Current geomagnetic conditions are quiet to unsettled (estimated NOAA Kp and K_Izmiran 1 to 3). Mainly quiet to unsettled conditions are expected to continue.

A crescent Venus shines along the western horizon at dusk in this clearing sky. The Earth’s sister planet is smiling between the low clouds near the bottom of the frame during its January 2nd conjunction with the slender, young crescent Moon above. Of course the lovely pairing of Moon and Venus crescents could be enjoyed in the new year’s skies around the the world. But the twin contrails in this scene belong to an aircraft above Appenzell, Switzerland. Soon to disappear from evening skies, Venus is heading toward its January 11th inferior conjunction and an appearance in predawn skies as planet Earth’s morning star by late January. And the Moon will be young again, too.

Soul Nebula (Sharpless 2-199, LBN 667) is emission nebulae in Cassiopeia. Several small open clusters are embedded in the nebula: CR 34, 632, and 634 (in the head) and IC1848 (in the body). The object is more commonly called by the cluster designation IC1848. Small emission nebula IC 1871 is present just left of the top of the head, and small emission nebulae 670 and 669 are just below the lower back area. This complex is the eastern neighbor of IC1805 (Heart Nebula) and the two are often mentioned together as the “Heart and Soul”.
