The Orion Molecular Cloud Complex (also often referred to as simply the Orion Complex) refers to a large group of bright nebulae, dark clouds, and young stars located in the constellation of Orion. The cloud itself is between 1,500 and 1,600 light-years away and is hundreds of light-years across. Several parts of the nebula can be observed through binoculars and small telescopes, with some parts (such as the Orion Nebula) being visible to the naked eye.
Nebulae within the complex:
the Orion Nebula
the Horsehead Nebula

We select the best works of amateur astrophotographers with details of equipment, shooting processing etc.
Solar activity has been at active levels over the last 24 hours. 6 C- and 1 M-class flares were recorded, all originating from NOAA 1967. The strongest was an M6-flare peaking at 16:11UT. The sunspot region still has a few magnetic delta structures. The x-ray background has been all day above the
Active conditions are expected to continue, with a slight chance on an X-class flare.
A partial halo CME was observed in LASCO/C2 starting at 08:12UT. It was most probably associated to the M2-class event that took place in NOAA 1967 (maximum at 06:39UT). It has a slow speed of about 350 km/s. A full halo CME was observed in LASCO/C2 starting 16:12UT. It was associated to the M6-flare, and had an initial plane-of-sky speed of 1735 km/s (latest CACTUS result). The bulk of the CME was directed away (to the southeast) from Earth. It is very likely this CME will overtake the partial
halo CME of the M2-event. Solar wind parameters are currently at average levels, with a speed near
350 km/s and Bz fluctuating between -3 and +3 nT. Geomagnetic conditions were quiet.
For the next 24 hours, solar wind may continue to be modulated by the effects of small coronal holes that have passed the central meridian on 27 and 29 January. Quiet geomagnetic conditions are expected for that period. Late on 1 February, Earth may receive a glancing blow from the 29 January CME, but little geomagnetic disturbances are expected. This may change upon the arrival of the CME from the M6-event, which is currently foreseen for the morning of 2 February. This may result in active geomagnetic conditions, with locally a minor storm possible.
