The Sun Online and solar activity. February 2, 2014

10 C- and 3 M-class flares were recorded over the last 24 hours. The existing delta structures in NOAA 1967 have further developed. The trailing portion of this region now consists of 2 big opposite polarity spots containing themselves spots of opposite polarity. The largest flares of the period (M2 and M4 peaking resp. at 08:20UT and 09:31UT) took place just north of these big spots. Extending to the northwest, an elongated delta structure of nearly 5 degrees long has further matured overnight. It
currently consists of several small spots of opposite polarity very close to each other. So far, it has produced only C-class flares. Another M2-flare peaked at 06:34UT. It was located just north of NOAA 1968’s trailing spot which has a magnetic delta structure.  The x-ray background has been all day above the C1-level.
In view of the various delta structures in NOAA 1967, there’s a good chance on a major X-class flare during the next 24-48 hours. Otherwise, active conditions are expected to continue.
Solar wind speed has been gradually increasing from 300 km/s to about 380 km/s since yesterday 08:45UT. Bz has been fluctuating between -5 and +5 nT, being mostly negative till 03:00UT. Geomagnetic conditions remained quiet. No shock of the M6 halo CME (30 January) has been detected so far, but the CME can still arrive during the following hours.
For the next period, quiet geomagnetic conditions with a slight chance on active levels are expected. On 4 February, Earth may receive a glancing blow from the partial halo CME that originated in NOAA 1968 (31 January).

Welcome to The World At Night. Sharing the night sky seen around the world, this view from Monument Valley, USA includes a picturesque foreground of famous buttes. Buttes are composed of hard rock left behind after water eroded away the surrounding soft rock. The two buttes on the image left are known as the Mittens, while Merrick Butte is on the right. Recorded in 2007 December, planet Mars is at the left of the skyscape, a glowing beacon of orange that is the brightest object in the frame. To the right of Mars lies the constellation of Orion. Betelgeuse is the reddish star near the center and the Belt of Orion and the Orion Nebula are farther right. Finally, the bright blue star Rigel appears above Merrick Butte in this stunning view of The World At Night.

Sh2-290: planetary nebula in constellation Cancer

Sh2-290 is an ancient planetary nebula. A planetary nebula is created when a low-mass star blows off its outer layers at the end of its life. Sh2-290 is one of the largest known planetary nebulae, with a diameter of about 7 parsecs. The bluish interior is from energized oxygen atoms. The bright side of the nebula is due to its interaction with ambient interstellar gas.

The Sun Online and solar activity. February 1, 2014

Numerous C- and 3 M-class flares were recorded over the last 24 hours, mostly originating from NOAA 1967. This region has three magnetic delta structures: two near the main spot, and one near the top of the region. The latter was the location of the strongest flare this period (M3 peaking at 07:23UT). One M-flare had NOAA 1968 as its source (M1 peaking at 15:42UT), which has developed more small spots of opposite polarity in its interior. This M1-flare was associated to a partial halo CME with a plane-of-sky
speed of 460 km/s. The bulk of the CME was directed to the northeast. The x-ray background has been all day above the C1-level.  Active conditions are expected to continue, with a chance on an X-class
flare. Solar wind speed has been varying between 300 and 350 km/s and Bz fluctuating between -3 and +3 nT. Geomagnetic conditions were quiet.
For the next 24 hours, active geomagnetic conditions with a slight chance on minor storm levels are  expected, in particular due to the arrival of the M6 CME (30 January) which is currently foreseen for the morning of 2 February. On 4 February, Earth may receive a glancing blow from the partial halo CME that originated in NOAA 1968 (31 January).
