The Sun Online and solar activity. January 18, 2014

During last 24 hours sixteen C-class flares were reported, majority of them originated from the active region currently on and behind the East solar limb. The strongest flare was the C8.9 flare which peaked at 16:08 UT on January 17. The flare originated from the active region situated just behind the East solar limb and was associated with the CME directed southward from the Sun-Earth line. We expect C-class flares are probably also isolated M-class flare in the following 24 hours.The Earth is inside a
slow solar wind with a speed of about 310 km/s. The interplanetary magnetic field is still stable with the magnitude between 2 and 3 nT. The glancing blow from the CME-driven shock wave, associated with the partial halo CME observed on January 14, is expected to arrive at the Earth today. Therefore we expect quiet to unsettled to geomagnetic conditions in the following hours. The CME-driven shock wave,  associated with a partial halo CME (limb event) on January 16, could be expected on January 20-21.

Apogee’s Full Moon

This big, bright, beautiful Full Moon rose over Lick Observatory Wednesday night. Traditionally a full moon in January might be called the Wolf Moon. But this moon reached its full phase on January 16, 4:54 UT, within about 2 hours of apogee, the most distant point in its elliptical orbit around planet Earth. That also makes it the smallest full moon of 2014. Of course the difference in apparent size between the largest and smallest full moons is hard to see, because the difference in distance between lunar apogee and perigee, or closest point in the Moon’s orbit, is only about 50,000 kilometers, while the Moon’s average distance is around 385,000 kilometers. Though not by much, this apogee’s full moon was also the smallest full moon of the last 1,000 years. It will keep that distinction until a slightly smaller full moon occurs close to apogee in 2154.

The Spaghetti Nebula (Simeis 147 / Sh2-240) Hydrongen-alpha


Simeis 147, also known as the Spaghetti NebulaSNR G180.0-01.7 or Sharpless 2-240, is a supernova remnant (SNR) that may have occurred in the Milky Way, on the constellation borders of Auriga and Taurus. Discovered in 1952 at the Crimean Astrophysical Observatory using a 25 inch Schmidt-Cassegrain telescope, it is a very difficult object to observe view due to its extreme low brightness. The nebulous area is fairly large with an almost spherical shell and filamentary structure. The remnant has an apparent diameter that covers approximately 3°, an estimated distance of approximately 3000 (±350)ly away and an age of approximately 40,000y old. It is believed that after its stellar explosion a rapidly spinning neutron star known as pulsar PSR J0538+2817 was left behind in the nebula core, emitting a strong radio signal.
