The Sun Online and solar activity. April 14, 2014

Six sunspot groups are reported by NOAA today. The most active of them is NOAA AR 2036 (no Catania number yet) that produced five low C-class flares and a C7.5 flare peaking at 04:38 UT. The second strongest flare of today, a C5.2 flare peaking at 08:00 UT, was produced by a still unnumbered sunspot group that just appeared from behind the south-east solar limb. We expect further flaring activity on the C-level from these two groups, with a good chance for an M-class event. The Earth is currently inside a slow (around 380 km/s) solar wind flow with average (5-6 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so.

An Unusual Globule in IC 1396

Is there a monster in IC 1396? Known to some as the Elephant’s Trunk Nebula, parts of gas and dust clouds of this star formation region may appear to take on foreboding forms, some nearly human. The only real monster here, however, is a bright young star too far from Earth to hurt us. Energetic light from this star is eating away the dust of the dark cometary globule near the top of the above image. Jets and winds of particles emitted from this star are also pushing away ambient gas and dust. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a much larger region on the sky than shown here, with an apparent width of more than 10 full moons.

NGC 6820 in Vulpecula

NGC 6820 is an emission nebula that surrounds open cluster NGC 6823 in Vulpecula, near M27, the Dumbbell Nebula. The nebula NGC 6820 is also called Sharpless catalog Sh 2-86.The most striking feature is the trunk-like pillar of dust and gas protruding from the east side of the nebula towards the open cluster,NGC 6823 in the west. The center of the open cluster is about two million years old and is predominantly represented by many young, bright blue stars. Outer parts of the cluster intimately involving pillars of emission nebula NGC 6820, contain even younger stars. The huge pillars of gas and dust are probably formed when surrounding gas and dust is pushed and eroded away by radiation from nearby stars. Remarkable dark globules of gas and dust are also visible in the nebula, much as is seen in the better known Eagle Nebula in Serpens or the Lagoon Nebula in Sagittarius.

Open star cluster NGC 6823 is about 50 light years across and lies about 6000 light years away.

The Sun Online and solar activity. April 14, 2014

The background level of the X-ray flux was at the B-class level and no C-class flares occurred during the past 24 hours. C-class flares can be expected from NOAA ARs 2034 and 2035. Geomagnetic conditions were unsettled. On April 13, unsettled to active conditions are still possible related to the arrival of the CH high speed stream.
