At the end of 2010 July, SOHO's Extreme ultraviolet Imaging Telescope (EIT) completed fourteen and a half years of synoptic observations of the low corona. SDO AIA images at much higher resolution and time cadence are now available for all the EIT wavebands, and three other EUV wavelengths as well.

The Extreme ultraviolet Imaging Telescope (EIT) is an instrument on the SOHO spacecraft used to obtain high-resolution images of the solar corona in the ultraviolet range.

The Extreme-ultraviolet Imaging Telescope (EIT) will provide wide-field images of the corona and transition region on the solar disc and up to 1.5 R⊙ above the solar limb. Its normal incidence multilayer-coated optics will select spectral emission lines from Fe IX (171 Å), Fe XII (195 Å), Fe XV (284 Å), and He II (304 Å) to provide ...

This page provides an overview of many online information resources relevant to the analysis of data from the SOHO/EIT instrument. Still can't analyse SOHO/EIT data?

Latest EIT full-field images. Starting 2010 August 1, EIT is obtaining only two sets of images in these four wavelengths per day. The Solar Dynamics Observatory (SDO) Atmospheric Imaging Assembly (AIA) obtains EUV images of the Sun every 12 seconds, and links to those images (updated every half hour) can be found at the SDAC latest images page.

2025年1月21日 · EIT will also provide images to support the planning of detailed spectroscopic investigations by the CDS and SUMER spectrometers on SOHO. EIT observations will be made in four narrow spectral bands, centered at 17.1 nm (Fe IX), 19.5 nm (Fe XII), 28.4 nm (FE XV), and 30.4 nm (He II) representing restricted temperature domains within a wide ...

2020年2月4日 · SOHO is an ESA/NASA collaborative mission within ESA's `Solar Terrestrial Science Program' (STSP), and it is also part of ISTP (International Solar Terrestrial Physics Program). So far, SOHO represents the most comprehensive space mission devoted to the study of the sun and of the heliosphere.

前者如SOHO卫星的极紫外成像望远镜( EIT)、白光日冕仪(LASCO)[7-9],SDO卫星的极紫外大气成像组件(AIA)等,可以观测各种太阳活动的形态、强度及其演化。 后者一般利用狭缝和光栅,可以同时得到沿狭缝方向一维空间多条谱线的光谱,进而通过扫描得到二维成像光谱,如SOHO 卫星的UVCS、CDS、 SUMER[10-12], Hinode 卫星的EIS, IRIS卫星等。 这些观测仪器为我们理解日冕物质抛射(coronal mass ejections, CME)及太阳耀斑等爆发现象的物理本质提供了丰富的信息;但 …
