The Sun Online and solar activity. March 03, 2014

There are currently 8 sunspot regions on the visible solar disk, with small delta’s observed in NOAA 1990 as well as in the trailing portions of both sunspot groups NOAA 1989 and 1991. The strongest flare of the past 24 hours was an M1 peaking at 23:19UT in active region NOAA 1986 near the northwest limb. From the currently available imagery, no Earth directed CMEs have been observed. The greater than 10MeV proton event that started following the X4 flare on 25 February, has ended shortly after midnight on 03 March.

Active conditions are expected, with an M-class flare possible from any of the active regions NOAA 1989, 1990 and 1991. On 2 March around 23:00UT (ACE), the magnetic field of the solar wind turned southward with other parameters remaining fairly constant. Solar wind speed has been around 350 km/s, with Bz varying between -4nT and -1nT. Geomagnetic conditions have been quiet and are expected to remain so.

Habitable Worlds

Is Earth the only known world that can support life? In an effort to find life-habitable worlds outside our Solar System, stars similar to our Sun are being monitored for slight light decreases that indicateeclipsing planets. Many previously-unknown planets are being found, including over 700 worlds recently uncovered by NASA’s Kepler satellite. Depicted above in artist’s illustrations are twelve extrasolar planets that orbit in the habitable zones of their parent stars. These exoplanets have the right temperature for water to be a liquid on their surfaces, and so water-based life on Earth might be able to survive on them. Although technology cannot yet detect resident life, finding habitable exoplanets is a step that helps humanity to better understand its place in the cosmos.

The Butterfly Cluster in Scorpius

The Butterfly Cluster (cataloged as Messier 6 or M6, and as NGC 6405) is an open cluster of stars in the constellation of Scorpius. Its name derives from the vague resemblance of its shape to a butterfly.

The first astronomer to record the Butterfly Cluster’s existence was Giovanni Battista Hodierna in 1654. However, Robert Burnham, Jr has proposed that the 1st century astronomer Ptolemy may have seen it with the naked eye while observing its neighbor the Ptolemy Cluster(M7). Charles Messier catalogued the cluster as M6 in 1764. It was not till the 20th century that star counts, distance, and other properties were measured.
