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

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.
