The Sun Online and solar activity. June 26, 2014

Catania 92 (NOAA AR 2096) produced the only C-class flare of past 24 hours, a C2.2 flare that peaked at 09:18 UT. More C-class flaring activity can be expected.The solar wind speed is at 350 km/s with interplanetary magnetic field magnitude of 5 nT. Geomagnetic conditions are quiet. The fast solar wind from an equatorial coronal hole is expected to reach the Earth within 48 hours, probably rising conditions to active  levels.

Conjunction by the Sea

Early morning risers were treated to a beautiful conjunction of Venus and waning Crescent Moon on June 24, captured in this seaside photo near Belmar, New Jersey, USA, planet Earth. The serene celestial pairing is seen above the Atlantic Ocean horizon as the eastern sky grows brighter with dawn’s early light. Wispy, scattered clouds appear in silhouette. But the exposure also reveals the night side of the lunar orb in the armsof the sunlit crescent. That shadowed part of the Moon, with hints of the smooth, dark lunar seas or maria, is illuminated by Earthshine, sunlight reflected from planet Earth itself.

IC 59, IC 63 and Gamma Cas

IC 59 (upper) and IC 63 nebulae lie about 600 light-years distant. They are slowly dissipating under the influence of ionizing ultraviolet radiation from hot, luminous star gamma Cas. Gamma Cas is physically located only 3 to 4 light-years from the nebulae. In fact, slightly closer to gamma Cas, IC 63 is dominated by red H-alpha light emitted as the ionized hydrogen atoms recombine with electrons. Farther from the star, IC 59 shows proportionally less H-alpha emission but more of the characteristic blue tint of dust reflected star light.
