• SolO surveys

  30 mai 2022, par Renaud Romagnan

  The composite survey SolO 8h covers the 08-16 UT time range (1pixel/60sec) and zooms are 1 hour long (1pixel/10sec). The composite survey SolO 24h covers the 00-24 UT time range (1pixel/180sec) and zooms are 3 hours long (1pixel/22.5sec).
  It is composed of EPD : the time histories of protons and electrons (A). a spectrum (B) NRH : a display of brightness distribution projected onto the heliocentric East/West or North/South direction versus time at 150 MHz (C) STIX : the count time (…)

• Solar Orbiter

  30 mai 2022, par Renaud Romagnan

  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 (…)

  General Introduction
  Spectrum_gui is a software designed to display and analyse dynamic radio spectra from various solar spectrographs. It is designed for ease of use.
  Through Spectrum_gui, the user reads and displays the input data, selects and substracts a backgroud, selects time and frequency intervals of interest, displays an Intensity vs (…)

• Welcome

  2 octobre 2018, par Abdallah Hamini

  The present web site is brought to you by the LESIA , UMR 8109, Observatoire de Paris-Meudon and is made possible thanks to a grant from the french Space Agency CNES.
  This radio survey project is a joint effort of the Paris Observatory, the Yunnan Observatory (China), the University of Sydney (Australia), the University of Athens, the University of Ioannina (Greece), the Solar Physics Branch of the Naval Research Laboratory (USA), The Royal Observatory of Belgium and the Indian Institute (…)

• ORFEES

  24 septembre 2018, par Florence HENRY

  The process to request ORFEES data has been changed.
  After clicking on Get Nancay Data button on the survey page you will be redirected on the Solar Radio Data Base @ Nancay webpage. This data base provides more flexibility and efficiency for data request.

• High Resolution Image

  23 juillet 2018, par Renaud Romagnan

  You can view here Rotational synthesis images.
  Their advantages, when compared to snapshot images, are : A better sensitivity and a strong reduction of interferences, both resulting from the long observation time. A better spatial resolution (respectively about 3 and 2 times better in the EW and NS directions) and a field of view wider by a factor 1.5 in the EW direction, due to a much more complete uv-coverage.
  The dynamical range in images of the quiet corona is much larger than in (…)
