North America and the Pelican

Image Credit & Copyright: Scott Rosen
Explanation: Here lie familiar shapes in unfamiliar locations. On the left is an emission nebula cataloged as NGC 7000, famous partly because it resembles our fair planet’s continent of North America. The emission region to the right of the North America Nebula is IC 5070, also known for its suggestive outlines as the Pelican Nebula. Separated by a dark cloud of obscuring dust, the two bright nebulae are about 1,500 light-years away. At that distance, the 4 degree wide field of view spans 100 light-years. This spectacular cosmic portrait combines narrow band images to highlight bright ionization fronts with fine details of dark, dusty forms in silhouette. Emission from atomic hydrogen, sulfur, and oxygen is captured in the narrow band data. These nebulae can be seen with binoculars from a dark location. Look northeast of bright star Deneb in the constellation of Cygnus the Swan.

Sun online. Solar activity. 3 September 2013

The solar events of the last 24 hours:

  • Solar activity has been quiet during the past 24 hours, featuring no C flares. There is a chance for C flares within the next 48 hours.
  • The solar wind speed decreased from 420 to 380 km/s in the past 24 hours.
  • Currently,  on the Sun there are 4 active regions with sunspots.

    The geomagnetic activity was at quiet levels (K Dourbes between 0 and 2; NOAA Kp between 1 and 3) during the past 24 hours. Quiet conditions (K Dourbes < 4) are expected for September 3 and 4, with a chance for active periods from the second half of September 4 onwards, due to the effects of a Coronal Hole high speed stream.
