DESCRIPTION
Off-limb observations 2007 May 7-10 Ulysses quadrature Hinode, SOHO (UVCS,CDS), TRACE, STEREO, G. Del Zanna V.Andretta, G. Poletto, H. Mason Y.K. Ko, A. Vourdilas, A. Bemporad In May 2007 Ulysses was at 55 0 south in quadrature with SOHO Measure electron temperatures (and ionization state), densities, abundances in active regions as function of height from 1 to 1.7 R o with SOHO/CDS, Hinode/EIS, SOHO/UVCS. Link them with in-situ measurements by Ulysses. We needed 1- an active region at the right time (planning constraints!) and place (around s) 2- Co-spatial and co-temporal measurements from the instruments..

• In May 2007 Ulysses was at 550 south in quadrature with SOHO• Measure electron temperatures (and ionization state), densities, abundances in
active regions as function of height from 1 to 1.7 Ro with SOHO/CDS, Hinode/EIS, SOHO/UVCS.
• Link them with in-situ measurements by Ulysses.
We needed 1- an active region at the right time (planning constraints!) and place (around 45-600 s)2- Co-spatial and co-temporal measurements from the instruments..

The sparse raster• 2” slit - 60s exposure
• sparse raster (8” step): cover a large FOV in 1h
• problems with Eclipses - Good signal in most lines
