Other names for sun corona11/10/2022 ![]() ![]() Much of the work was done with a spectrometer (using the Extreme UV Spectroheliograph and the grazing incident X-Ray spectroheliograph) in the late-1960’s on the Orbiting Solar Observatory No. Ion species of Fe XVIII, Fe XXIV, Fe XXI are normally generated during CME events, whose emission lines correspond to one to twelve million kelvins. The largest amount of energetic ‘metals’ is FeXX and Fe XXIII/IV lines, though all of the X-ray lines in the corona are from Fe IX to XXIII. It is currently known that 0.07% of the corona is Na X, Sodium will nine electrons removed, and > 0.05% of Cl VII, with six electrons removed. #Other names for sun corona generator#Coronal holes are the source of solar wind and a generator for space weather activity. The hole is the large dark spot in the middle of the sun. And enjoy more 3 D space imagery here – at a big Martian crater through the eyes of the Opportunity rover.Ĭaption: This STEREO image features an active region and a coronal hole. #Other names for sun corona movie#Then, I suggest to pause the movie at several intervals for a longer look. First, watch the short movie with you 3 D glasses. You’ll need to pull out your red-cyan 3 D anaglyph glasses.

They are also the source regions of the fast solar wind, which “blows” at a relatively steady clip of 1.8 million mph. Coronal holes are areas of the sun’s surface that are the source of open magnetic field lines that head way out into space. According to a NASA press release, the coronal holes appear dark at the extreme UV wavelength of 193 Angstroms because there is just less of the material – ionized iron- that is being imaged.Ĭaption: This timelapse video shows a coronal hole, as captured in ultraviolet light by NASA’s Solar Dynamics Observatory around Jan. ![]() In a video here, one hole is above the suns equator and the other is below. The two holes developed over several days. After traveling through space for a few days the particles will impact the Earth and may spark the formation of some auroral activity for lucky spectators. The fast solar wind travels at approximately 800 km/s (about 1.8 million mph). Image: NASA/Solar Dynamics Observatory/Atmospheric Imaging Assembly (AIA)Ĭoronal holes on the sun’s surface are the source of open magnetic field lines and are areas from which high-speed solar wind particles stream out into space. New observations reveal a link between hot plasma and jets propelled upward from the region immediately above the Sun's surface and help explain why the Sun's outer atmosphere, or corona, is much hotter than its surface. Colors represent different gas temperatures: ~800,000 kelvin (K) (blue), ~1.3 million K (green), and ~2 million K (red).

SDO research results on the solar corona are featured as the cover photo and story for the current issue of Science magazine on Jan. ![]()
