Welcome to the SUMER pages at NASA's Goddard Space Flight Center.
SUMER is a UV telescope and spectrometer that was designed and built with
international cooperation at the Max-Planck-Institut für Aeronomie (MPAe),
Lindau, Germany, from 1987 to 1995. It is now an instrument on-board
the ESA/NASA spacecraft SOHO, which was launched on 02 Dec 1995. Since the
beginning of 1996, SUMER works successfully at a distance approximately 1.5
million kilometers from Earth towards the Sun and delivers research data about
the solar atmosphere that are analysed and archived at various institutions.
Example: SUMER raster scan of magnetic loops
The structure of magnetic loops over an active region at the solar limb,
observed by SUMER on 06 May 1996. Left: Intensity image of the
emission line O VI 1037, formed in the transition region at a temperature
around 300 000 K.
Right: Doppler shift image of the same line; blue denotes movement
towards the observer, red denotes movement away from the observer.
