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.

3 天之前 · The Very Latest SOHO Images NOTICE: SDO/HMI Continuum and SDO/HMI Magnetogram image outage due to a cooling water line burst in the Joint Science Operations Center (JSOC) at Stanford University on 2024-11-26.

2 天之前 · EIT (Extreme ultraviolet Imaging Telescope) images the solar atmosphere at several wavelengths, and therefore, shows solar material at different temperatures. In the images taken at 304 Angstrom the bright material is at 60,000 to 80,000 degrees Kelvin.

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 EIT instrument is sensitive to light of four different wavelengths : 17.1, 19.5, 28.4, and 30.4 nm , corresponding to light produced by highly ionized iron (XI)/(X), (XII ...

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.

Electrical impedance tomography (EIT) is a noninvasive type of medical imaging in which the electrical conductivity, permittivity, and impedance of a part of the body is inferred from surface electrode measurements and used to form a tomographic image of that part.

You should compare these four EIT images to each other and to the SOHO MDI images that show you where sunspots are. Try to determine if the active places (bright spots) in EIT images occur near sunspots.

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.

In this work, nine different real-time methods were compared for reconstruction and post-processing of EIT images with the goal of using an anatomical atlas of representative simulated EIT data and images for a population of interest.

Electrical impedance tomography (EIT) is a bedside monitoring tool that noninvasively visualizes local ventilation and arguably lung perfusion distribution. This article reviews and discusses...
