SOLAR ULTRAVIOLET MEASUREMENTS OF EMITTED RADIATION

SOLAR ULTRAVIOLET MEASUREMENTS OF EMITTED RADIATION


There is a version in German language for some of these pages.
Es gibt eine deutschsprachige Version für einige dieser Seiten.

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. More examples in the SUMER Picture Gallery and the SUMER Slide Shows.
