Sun Online. Solar activity. 2013 August, 30

A partial halo CME (Coronal Mass Ejection), associated with a C8.3 flare, was detected by LASCO C2 on August 30th around 02:48 UT. It has an angular width of around 150° and
an estimated speed of about 1000 km/s. With this speed, the estimated time of arrival at Earth is on August 31th around 21:00.

A second partial halo CME was detected by LASCO C2 on August 29th around
06:00 UT. Most material of this CME is southbound, but a shockwave might
arrive on Earth. With an estimated speed of around 430 km/s this shockwave
is expected to arrive on September 2d around 20:00 UT.

A Sagittarius Triplet

Explanation: These three bright nebulae are often featured in telescopic tours of the constellation Sagittarius and the crowded starfields of the central Milky Way. In fact, 18th century cosmic tourist Charles Messier cataloged two of them; M8, the large nebula left of center, and colorful M20 on the right. The third, NGC 6559, is above M8, separated from the larger nebula by a dark dust lane. All three are stellar nurseries about five thousand light-years or so distant. The expansive M8, over a hundred light-years across, is also known as the Lagoon Nebula. M20’s popular moniker is the Trifid. Glowing hydrogen gas creates the dominant red color of the emission nebulae, with contrasting blue hues, most striking in the Trifid, due to dust reflected starlight. The colorful skyscape recorded with telescope and digital camera also includes one of Messier’s open star clusters, M21, just above the Trifid.

Sun Online. Solar activity. 2013 August 29

There was 1 C-class flare (C1.3) in the past 24 hours.
An M-class flare is possible next 24 hours in one of the Active Regions.

Solar wind speed is around 380 km/s. Geomagnetic conditions where quiet, but are
expected to reach active to minor storm  in the evening of August 30th due to the arrival of the fast stream of a coronal hole.
