SOLARNET Trans-national Access and Service Programme supports the access of the European solar Physics community to some of the best European telescopes: GREGOR, THEMIS, SST, VTT located at Tenerife and La Palma, and to IBIS/DST and ROSA/DST instruments, installed at US Dunn Solar Telescope.

Every facility is offering an average of 20 observing days per year to external observers.

SOLARNET is also supporting the access to the most demanded European Science Data Centre: HINODE, BE-WISSDOM, and GSC-SDO. Access to these database repositories is freely provided through internet connection.
