The Sun Online and solar activity. March 11, 2014

There were four M flares and four C flares on the Sun during the past 24 hours, mostly released by NOAA AR 12002 and 11996. The brightest one was an M3.5 flare from NOAA AR 11996 peaking at 03:50 UT on March 11. In the next 48 hours, the probability for C flares is very high (95%) and for M flares around 75%, mainly from NOAA AR 12002 and 11996. There is a chance (35%) for an X flare.In the past 24 hours, solar wind speed as observed by ACE gradually decreased from around 340 km/s to around 300 km/s, while the magnitude of the Interplanetary Magnetic Field (IMF) varied between 3.5 and 6.5 nT. In the past 24 hours, geomagnetic conditions were quiet (K Dourbes between 0 and 3; NOAA Kp between 0 and 3). Quiet geomagnetic levels are expected on March 11, 12, and 13.

In the Heart of the Rosette Nebula

In the heart of the Rosette Nebula lies a bright open cluster of stars that lights up the nebula. The stars of NGC 2244 formed from the surrounding gas only a few million years ago. The above image taken in January using multiple exposures and very specific colors of Sulfur (shaded red), Hydrogen (green), and Oxygen (blue), captures the central region in tremendous detail. A hot wind of particles streams away from the cluster stars and contributes to an already complex menagerie of gas and dust filaments while slowly evacuating the cluster center. The Rosette Nebula’s center measures about 50 light-years across, lies about 4,500 light-years away, and is visible with binoculars towards the constellation of the Unicorn (Monoceros).

Sharpless 171 in Cepheus

Cosmic pillars of cold molecular gas and clouds of dark dust lie within Sharpless 171, a star-forming region some 3,000 light-years away in the royal constellation Cepheus. This tantalizing false-color skyscape spans about 20 light-years across the nebula’s bright central region. It also highlights the pervasive glow of emission from atomic gas using narrowband filters and a color palette made popular in Hubble Space Telescope images. Powering the nebular glow are the young, hot stars of a newly formed cluster, Berkeley 59. Of course, this star-forming region is entry number 171 in the famous 1959 catalog of emission nebulae compiled by astronomer Stewart Sharpless.
