California Nebula

30 ноября

 

The California Nebula (NGC 1499) is an emission nebula located in the constellation Perseus. It is so named because it appears to resemble the outline of the US State of California on long exposure photographs. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually. It can be observed with a Hβ filter (isolates the Hβ line at 486 nm) in a rich-field telescope under dark skies.[1] It lies at a distance of about 1,000 light years from Earth. Its fluorescence is due to excitation of the Hβ line in the nebula by the nearby prodigiously energetic O7 star, xi Persei (also known as Menkib, seen at center below it in the inset at right).

Rosette Nebula

29 ноября

 

The Rosette Nebula (also known as Caldwell 49) is a large, circular H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula’s matter.

INFO FROM SIDC – RWC BELGIUM 2014 Nov 27 12:54:59 NOAA 2222 developed close to the southeast limb and is actively flaring. It was responsible for at least 10 C-class flares, including a C8.2 flare peaking at 00:47UT which was the strongest event of the observing period. Departing region NOAA 2209 was the only other region to produce a C-class flare. The other regions were quiet, with NOAA 2219 having some mixed polarities. The x-ray background flux increased from about B9 to nearly C2. A filament eruption was observed in the NW quadrant around 16:00UT on 26 November. A slow CME first observed in LASCO/C2 at 17:36 may have been associated to it. The other filaments were quiet. None of the observed CMEs are directed to Earth. Low-level M-class flares are possible. A sector boundary crossing (SBC) occurred around 03:00UT. IMF turned towards the Sun. Solar wind speed gradually increased from about 300 to 400 km/s. Bz varied between -7 and +9 nT, but was mostly positive after the SBC. The geomagnetic field was quiet. Geomagnetic conditions are expected to be quiet to unsettled, with an isolated active period not excluded.

Triangulum Galaxy

 

 

28 ноября

 

The Triangulum Galaxy is a spiral galaxy approximately 3 million light-years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598, and is sometimes informally referred to as the Pinwheel Galaxy, a nickname it shares withMessier 101. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, which includes the Milky Way, theAndromeda Galaxy and about 44 other smaller galaxies. It is one of the most distant permanent objects that can be viewed with thenaked eye.

INFO FROM SIDC – RWC BELGIUM 2014 Nov 26 12:25:23 Four C-class flare were observed, with NOAA 2217 producing the strongest event of the period (C2.9 peaking at 06:17UT). Slowly developing region NOAA 2219 and a new, currently unnumbered, region near the east limb merit some attention, as they were the sources of the other C-class flares. Numerous, but quiet, filaments are present on the solar disk, with the longest measuring 40 degrees and located in the NE quadrant. No Earth-directed CMEs were observed. Further C-class flaring is expected, with a small chance on an isolated M-class flare. Solar wind speed declined from about 400 to 320 km/s. Bz was mostly negative and varied between -6 and +4 nT. The IMF is directed away from the Sun. The geomagnetic field was quiet to unsettled (K<4), and is expected to remain so. Effects from an expected Sector Boundary Crossing and the possible high speed stream from the extension of a coronal hole may result in an isolated active period on 27-28 November.

The North America Nebula

27 ноября

The North America Nebula (27 ноября or Caldwell 20) is an emission nebula in the constellation Cygnus, close to Deneb (the tail of the swan and its brightest star). The remarkable shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. It is sometimes incorrectly called the “North American Nebula”.

INFO FROM SIDC – RWC BELGIUM 2014 Nov 25 12:24:52

Three C-class flares were observed, all originating from NOAA 2217. The
strongest was a C2.8 flare peaking at 18:09UT (24 November). The other five
sunspot regions were quiet. No Earth directed CMEs were observed.

More C-class flares are expected, with a small chance on an isolated
M-class flare.

Solar wind was at nominal values, with wind speed mostly between 350 and
400 km/s, and Bz between -6 and +4 nT. The IMF is directed away from the
Sun. The geomagnetic field was quiet to unsettled (K<4), and is expected to
remain so.

Andromeda Galaxy

26 ноября

 

The Andromeda Galaxy /ænˈdrɒmɨdə/ is a spiral galaxy approximately 2.5 million light-years (2.4×1019 km) from Earth[4] in theAndromeda constellation. Also known as Messier 31, M31, or NGC 224, it is often referred to as the Great Andromeda Nebula in older texts. The Andromeda Galaxy is the nearest spiral galaxy to our Milky Way galaxy, but not the nearest galaxy overall. It gets its name from the area of the sky in which it appears, the constellation of Andromeda, which was named after the mythological princessAndromeda. The Andromeda Galaxy is the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum Galaxy, and about 44 other smaller galaxies.

INFO FROM SIDC – RWC BELGIUM 2014 Nov 24 12:16:19

Five low-level C-class flares were observed over the last 24 hours. The largest was a C4.1 peaking at 11:04UT in NOAA 2217, which was also the source of 3 other C2 flares. One of these peaked on 23 November at 16:14UT and was associated to a non-Earth directed CME, first visible in LASCO at 16:24UT. NOAA 2216 produced the remaining C2 flare. The other regions were quiet, with NOAA 2209 still maintaining a weak delta spot in its trailing portion. More C-class flares are expected, with a chance on an isolated M-class flare. The IMF is directed away from the Sun, with Bz varying between -7 and +4 nT. Solar wind speed varied between 470 and 360 km/s and is currently near 400 km/s. The geomagnetic field was quiet to unsettled (K<3), and is expected to remain so, with an isolated active period possible.

Messier 10

25 ноября

 

Messier 10 or M10 (also designated NGC 6254) is a globular cluster of stars in the equatorial constellation of Ophiuchus. The object was discovered by the French astronomer Charles Messier on May 29, 1764, who cataloged it as number 10 in his catalogue and described it as a “nebula without stars”. In 1774, German astronomer Johann Elert Bode likewise called it a “nebulous patch without stars; very pale”. Using larger instrumentation, German-born astronomer William Herschel was able to resolve the cluster into its individual members. He described it as a “beautiful cluster of extremely compressed stars”. William Parsons, 3rd Earl of Rosse thought he could distinguish a dark lane through part of the cluster. The first to estimate the distance to the cluster was Harlow Shapley, although his derivation of 33,000 light years was much further than the modern value.
