Aim of workshop- Latest theoretical ideas for coronal heating- Observational results (SOHO, Yohkoh, TRACE, and RHESSI)- Looking towards the future space missions
2004 September 6 - 9 University of St Andrews, UKhttp://www.soho15.org/

Future solar missions• Demands for better spatial and temporal resolution
(in terms of coronal heating)- small scale magnetic structures - wave or oscillation
• “Golden age” continuesSolar-B (2006)STEREO (2006)Solar Dynamics Observatory (2008)Solar Orbiter (2013)
• We should understand their capabilities and limitations to make a suitable observation plan

Solar-B• SOT (Solar Optical Telescope)
50cm aperture, diffraction limited (0.25” or 175km)Intensity and vector magnetic field measurement- Narrow band filter- Broad band filter- Spectrograph
• XRT (X-Ray Telescope)Full or partial Sun, 1”Temperature range 0.5-20 MK
• EIS (EUV Imaging Spectrometer)170-210Å and 250-290Å (mainly 1-10MK lines)Doppler velocity (2km/s at best)Temperature and Density Diagnostics
Launch 2006

What’s next ?
• No (approved) mission after 2013Solar Probe (NASA) ?Solar-C (JAXA) ?
• We should clarify the desired features for the following mission
