Solar Orbiter

The Radio/Solar Orbiter (SolO) pages combine radio observations from ground and space with quick-look plots of X-ray light curves at selected photon energies from Solar Orbiter / STIX and time histories of the intensities of energetic electrons and protons in selected energy ranges from Solar Orbiter / EPD.

The plot on the top right indicates the relative position of Solar Orbiter with respect to the Sun-Earth axis on the given day. Please be aware that during certain periods, the view of the Sun provided by ground-based instruments cannot be directly compared to the observations from Solar Orbiter.

The Spectrometer/Telescope for Imaging X-rays (STIX) is described at The quick-look plots on the present web site are produced from low-latency data (not science data). They show the count time histories in 20s time intervals in three photon energy channels (4-10, 10-15, 15-25 keV). The time axis is the arrival time of photons at 1 AU, corrected from the light propagation time between the satellite and the earth using the coordinates of the spacecraft provided by the SPICE kernels.
The Energetic Particle Detector EPD is described at . The quick-look plots on the present web site show the time histories of protons (energy ranges 7.075-28.33 MeV, 47.05-104.8 MeV) and electrons (energy ranges 53-73 and 282-397 keV), drawn from low-latency data. The intensities are averages over the four viewing directions of EPD. The time axis is the time at the spacecraft.

The data shown are quicklook-data, used for giving an overview of observations and a first guide to the event selection for scientific investigations. They are not suited for scientific publications. Please refer to the instrument web sites for advise on the recovery and use of science-ready data.
