Solar activity continues at the C-class flaring level. Returning NOAA AR 2088 (no Catania number) produced a C3.4 flare with peak at 07:44 UT. More C-class and probably M- class flares can occur as this region and NOAA AR 2082 (no Catania number) rotate today into the visible solar disk. Geomagnetic conditions are quiet. The arrival of a fast solar wind stream today will increase conditions to unsettled to active levels.

Orion’s belt runs just along the horizon, seen through Earth’s atmosphere and rising in this starry snapshot from low Earth orbit on board the International Space Station. The belt stars, Alnitak, Alnilam, and Mintaka run right to left and Orion’s sword, home to the great Orion Nebula, hangs above his belt, an orientation unfamiliar to denizens of the planet’s northern hemisphere. That puts bright star Rigel, at the foot of Orion, still higher above Orion’s belt. Of course the brightest celestial beacon in the frame is Sirius, alpha star of the constellation Canis Major. The station’s Destiny Laboratory module is in the foreground at the top right.

NGC 1491 (also designated SH2-206 and LBN 704) is a bright emission nebula and HII region, located on the edge of a vast cloud region of neutral gas, about 10,700 light-years away in the Perseus arm of our Milky Way Galaxy in the constellation Perseus.

There were two partial halo CMEs in past 24 hours. The first one at 21:38 UT (LASCO-C2, related to a CACTus alert) on June 26 in the northeast and the second one at 06:12 UT on the northwest. Both events are backsided and not expected to arrive to the Earth.
