The Sun Online and solar activity. January 3, 2014

The Sun produced seven C flares and one M flare during the past 24 hours. NOAA AR 1944 was responsible for most of the flaring activity. NOAA AR 1944 has grown in size and evolved to a beta-gamma region. NOAA AR 1936 shows some decay and is approaching the west limb. More M flares are possible (probability 50%), especially from NOAA ARs 1936 and 1944. There is a slight chance for an X flare (15%). We maintain the warning condition for proton events. Solar wind speed measured by ACE reached a maximum of 650 km/s, but has now declined to about 500 km/s. The magnitude of the
interplanetary magnetic field declined from 8 to 4 nT, with a Bz-component varying between -6 and +5 nT.  Estimated NOAA Kp and local K_Izmiran reached a maximum of 5 due to the influence of the coronal hole high speed stream. Current geomagnetic conditions are quiet to unsettled (Kp and K_Izmiran 2 to 3). Unsettled to minor storm conditions (local K 3 to 4) are possible due to the possible arrival of the CMEs of December 29 and December 31.

Lovejoy in the New Year

A rival to vanquished Comet ISON in 2013, Comet Lovejoy (C/2013 R1) still sweeps through early morning skies, captured in this starry scene on New Year’s day. The frame stretches some 3.5 degrees across a background of faint stars in the constellation Hercules. Only just visible to the naked eye from dark sites before dawn, Lovejoy remains a good target for the northern hemisphere’s binocular equipped skygazers. But this deep exposure shows off Lovejoy’s beautiful tails and tantalizing greenish coma better than binocular views. Not a sungrazer, this Comet Lovejoy made its closest approach to the Sun around December 22, looping high above the ecliptic plane. Now headed for the outer Solar System, Lovejoy began the new year about 6.7 light-minutes from planet Earth.
