INFO FROM SIDC - RWC BELGIUM 2014 Oct 20 13:00:17 Six sunspot groups are reported by Catania today. The main source of the solar flaring activity is the Catania sunspot group 88 (NOAA AR 2192) that is growing in size and complexity. Now it has beta-gamma-delta configuration of its photospheric magnetic field. After yesterday's X1.1 flare, the strongest flare was the M3.9 flare peaking at 09:11 UT today. This flare was not accompanied by a CME. We expect more flaring activity up to X-level from this sunspot group. The Earth is currently inside a solar wind flow with intermediate speeds (around 500-550 km/s). This flow might be associated with a narrow low-latitude coronal hole that passed the solar central meridian on October 17-18. The interplanetary magnetic field (IMF) magnitude was elevated (up to 9 nT), and the IMF was directed predominantly southward during the last several hours. Intervals of active geomagnetic conditions (K = 4) were reported by Dourbes and NOAA. We expect quiet to active geomagnetic conditions in the coming hours.
During the past 24 hours, one X flare and nine C flares were released by beta-gamma region NOAA AR 2192. The long duration X1.1 flare peaked at 5:03 UT on October 19. It seems that the X flare was not accompanied by a CME. In the next 48 hours, X flares are possible, especially from AR 2192.Over the last 24 hours the solar wind speeds observed by ACE varied between about 355 and 515 km/s, with current speed values around 400 km/s. The magnitude of the Interplanetary Magnetic Field (IMF) varied between 2 and 11 nT, with current values around 10 nT. Solar wind speeds are expected to stay nominal until October 22, when they are likely to increase to well over 500 km/s due to the expected arrival of a coronal hole high speed stream. Geomagnetic conditions during the last 24 hours were quiet to active (K Dourbes between 2 and 4; NOAA Kp between 2 and 4). Quiet geomagnetic levels (K Dourbes < 4) with active excursions (K Dourbes = 4) are expected on October 19, 20 and 21.
NGC 2244 (also known as Caldwell 50) is an open cluster in the Rosette Nebula, which is located in the constellation Monoceros. This cluster has several O-type stars, super hot stars that generate large amounts of radiation and stellar wind.
The age of this cluster has been estimated to be less than 5 million years and its two brightest stars are HD 46223 of spectral classO4V, 400,000 times brighter than the Sun, and approximately 50 times more massive, and HD 46150, whose spectral type is O5V, has a luminosity 450,000 time larger than that of our star, and is up to 60 times more massive, but it may actually be a double star.
