Welcome to the SUMER pages, based at the Max Planck Institute for Solar System
Research (MPS). SUMER is a VUV telescope and spectrometer,
designed and built at this institute from 1987 to 1995 with international cooperation.
It is now an instrument on board the ESA/NASA
spacecraft SOHO, which was launched on 02 December 1995. Since the beginning
of 1996, SUMER operates on SOHO 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 MPS and other
institutions. SUMER has now been put in hibernation since August 2014.
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.

SUMER Picture Gallery and the
SUMER Slide Shows.
