The Sun Online and solar activity. May 1, 2014

Five sunspot groups are visible at the front side of the disk. Flaring activity was limited to six B-class flares. The sunspot groups were relatively stable. The CME mentioned in the last bulletin was a backsided event and is as such not-Earth bound. No Earth-directed CMEs are observed. C-class flares can be expected for the next 48 hours.  Solar wind speed, measured by ACE, has increased to 350 km/s. The magnitude of the
interplanetary magnetic field remains near 10 nT, and the vertical component varied between -10 and +8 nT.
Geomagnetic conditions were quiet to active (local K at Dourbes and global NOAA Kp up to 4). Quiet to unsettled geomagnetic conditions are expected for the next 48 hours.

Brisbane Sunset Moonset 

Image Credit & Copyright: Stephen Mudge

In skies over Brisbane at the southeastern corner of Queensland, Australia, Planet Earth, the Sun and New Moon set together on April 29. There the celestial line-up, the first solar eclipse of 2014, was seen as a partial solar eclipse. This dramatic composite is a digital stack of images taken about 5 minutes apart with telephoto lens and solar filter. It follows the eclipse in progress, approaching a western horizon wherecrepuscular rays from cloud banks in silhouette joined the silhouetted Moon. From Brisbane, the maximum eclipse phase with the Moon covering about 25% of the Sun occurred just after sunset. Only from a remote spot on the continent of Antarctica was it even possible to see the eclipse in its brief annular phase, the entire dark lunar disk surrounded by a thin, bright ring of fire.

Lagoon Nebula in Sagittarius


The Lagoon Nebula (catalogued as M8, and as NGC 6523) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as a H II region.

The Lagoon Nebula was discovered by Giovanni Hodierna before 1654 and is one of only two star-forming nebulae faintly visible to the naked eye from mid-northern latitudes. Seen with binoculars, it appears as a distinct oval cloudlike patch with a definite core. A fragile star cluster appears superimposed on it.
