The Sun Online and solar activity. June 19, 2014

During the past 24 hours, only three C-class flares were reported, and all of them were weak (below C2 level). NOAA AR 2089 has the beta-gamma configuration of its photospheric magnetic field, but it produced only one
C-class flare during this period. We expect flaring activity to continue on the C-level, in particular in NOAA ARs 2087 and 2089, as well as in the newly emerged NOAA AR 2095. Yesterday evening the interplanetary magnetic field (IMF) magnitude reached 10 nT, with intervals of negative north-south IMF component. Active to minor storm geomagnetic conditions were reported (Kp = 5 by NOAA, K = 5 by IZMIRAN, K = 4 by Dourbes). Currently the Earth is inside a slow (around 440 km/s) solar wind flow with average (around 5 nT) IMF magnitude. The geomagnetic conditions are quiet and are expected to remain so.

The central bulge of our Milky Way Galaxy rises above a sea of clouds in this ethereal scene. An echo of the Milky Way’s dark dust lanes, the volcanic peak in foreground silhouette is on France’s Réunion Island in the southern Indian Ocean. Taken in February, the photograph was voted the winner of the 2014 International Earth and Sky Photo Contest’s Beauty of the Night Sky Category. This and other winning and noteable images from the contest were selected from over a thousand entries from 55 countries around planet Earth. Also featured in the contest compilation video (vimeo), the moving images are a testament to the importance and beauty of our world at night.

Rho Ophiuchi

The Rho Ophiuchi cloud complex is a large star-forming region in the constellation Scorpius. The bright red supergiant star, Antares, is a prominent feature in the area, and reflects its light off the nearby clouds of gas.
