Resurgence of Solar Activity: Highlights and Challenges in Solar Research

The solar activity has seen a notable resurgence, with sunspots making a return and posing no threat of planetary destruction, particularly on January 4, 2011, during an alignment of the Sun, Moon, and Earth. STEREO spacecraft have enabled full solar surface visibility since February 2011, marking a golden age for observational solar physics. Upcoming initiatives like SN-IV and ESIO aim to advance solar research, while serious external challenges like mission extensions and selection for new projects remain critical for the future of solar science.

  1. ROB-OD4 contribution Highlights, opportunities, challenges

  2. Solar activity resurrected The spots are back!

  3. No planetary destruction on Jan 4 2011 Despite lining up of Sun, Moon, Earth and PROBA2 Sun Moon Earth

  4. No planetary destruction on Jan 4 2011 moon Sun Despite lining up of Sun, Moon, Earth and PROBA2 Earth Sun Moon Earth

  5. Confirmed: the Sun is a sphere Since Feb 2011, the two STEREO spacecraft can now see the complete solar surface.

  6. We are not alone SOTERIA Capacity Building Workshop Feb 17- Feb 18 2011 PROBA2 Science Working Group Feb 19- Feb 20 2011

  7. The sun is a movie star SDO First light: April 20 2010 USET in Global H-alpha Network PROBA2 in full science phase since March 2010! > 328000 SWAP images, >200 Gb LYRA Golden age of observational solar physics: the Sun has never been imaged this much.

  8. A New Hope • Upcoming: • SN-IV: start of regular operations • ESIO: successor to SWAP & LYRA? • Virtual Space Weather Modelling Center • High Performance Distributed Solar Imaging and Processing System SN-1: Space weather assets database

  9. Serious stuff:External Challenges • Solar Orbiter selection • PROBA2 mission extension in SSA • PROBA3 • SSA: SN-IV, ESIO
