Bulletins, forecasts and alerts

  5. Solar Physics at ROB Solar Physics (pure science) Scientific services (applied science) microscales macroscales Data collection and distribution Space WeatherMonitoring Understanding the small-scale plasma behavior, coronal heating Understanding the large scale dynamics of the solar atmosphere, flares & CMEs. Bulletins, forecasts and alerts

  6. Solar Physics at the Microscales Smallest flares are also fastest Smallest flares contribute most

  7. Solar Physics at the Microscales Smallest flares are also fastest Smallest flares contribute most • State-of-the-art instruments • Highest spatial resolution imaging • Image cadence correspondingly fast • Multi-wavelength Instrumentrequirements

  8. AIA &

  9. Solar Physics at the Macroscales Precursors to coronal mass ejections? CME statistics? SOHO - EIT SOHO -LASCO

  10. Solar Physics at the Macroscales Precursors to coronal mass ejections? CME statistics? Instrumentrequirements • fast EUV full disk imaging • coronagraphy & heliospheric imaging

  11. Space weather monitoring

  12. Space weather monitoring Instrumentrequirments • EUV full disk imaging and coronagraphy • Emphasis on continuous coverage, stability of operations and calibration • Solar indices

  13. Overview priorities microscales macroscales Space Weather • High resolution & multi-wavelength • Continuous fast EUV full disk observations • Coronagraphy & heliospheric imaging • Solar activity indices ++ + - - ++ ++ - ++ ++ + + ++

  14. Being built Stereo (2006) CMEs Solar-B (2006) Magnetism in the Corona PROBA2 (2007) CMEs & flares SDO (2008) 1st LWS mission PICARD (2009) Being defined PROBA3 (2011) Advanced coronagraph SMESE Kuafu-A (2012) Space Weather Science Solar Orbiter (2015) Connecting in-situ and remote sensing High resolution Cosmic Vision solar mission 2020+ ? Future solar space missions

  15. PROBA3 • Inner coronographic Science investigations • Link X-ray and/or EUV disc imaging with higher Corona observations • SpW monitoring value • No other coronagraph at the time of operations (2012) • 18h/day, but for only 1 year • Complementary payload TBD • Similar to Stereo-HI or PROBA2-LYRA?

  16. KUAFU • Successful fast-progressing program • Focus on the Science of Space Weather • Strong ILWS blessing, complement SDO • Flexible remote sensing payload • Innovative concepts, significant ressources • Permanent stereo? • Moses (spectro-imaging) • (polarimetric) Ly-alpha imager (S.O. preparation) • Important role of Belgium • Pierre Rochus (CSL) EDI PI

  17. Solar Orbiter • Quasi-total Science Community support • The one ESA solar mission after SOHO • Mission profile • Explore inner-heliosphere, Co-rotation vantage point, out-of-the ecliptic (38° but in 2024) • Large interest for In Situ  Remote Sensing connection • Belgian (ROB/CSL) interest for the Full Sun Imager • Schedule and funding unclear (@ Time of writing)

  18. Parameters limiting Solar (Orbiter) UV observations The higher effective area , the better Signal-to-Noise ratio should be maintained or increased. Radiance of Solar features (filling factor will help?) Distance to Sun. From 1 to 0.2 AU the S.O. orbit brings 25. Time constants. To be divided by 100 (or more!) Area @ Sun. From 500 km (TRACE) to 35-75 km, Solar Orbiter needs to divide ASun by ~100

  19. ROB assets in Solar space experiments • Heritage in EUV observations • Data exploitation, innovative instrument design, calibrations, advanced processing, Science operations… • Development of UV detectors • LYRA (2002), BOLD (2006) • Science Operation Data centre • PROBA2, PICARD, Kuafu TBC • On-board S/W • Advanced compression schemes, onboard algoritmics • SWAP, LYRA, Smese tbc, S.O.-EUI tbc

  20. Beyond 2018 • Forthcoming ESA Cosmic Vision call • Might be only one A.O. • Community not very ready (energy put to maintain S.O.) • RISE: powerful obs at Earth orbit + probe • Solarnet: very high resolution mission by interferometry. SIDC offered to lead • NASA • Sentinels • Solar Probe?? • the “evolving Great Observatory” concept
