Daily Note and User Entry: Active Region on Limb
Request to SOT: Quiet Sun magnetic fields SOT/FG: G-band and Ca II H filtergrams for studying connections between internetwork fields and chromospheric structure SOT/SP: Sequence of short scans in Fe I 630.2nm Active region magnetism SOT/FG: G-band and Ca II H filtergrams for studying connections between internetwork fields and chromospheric structure SOT/SP: Sequence of short scans in Fe I 630.2 nm
Scientific Objectives: We are planning to carry out two kinds of study in this unique opportunity: characterization of quiet Sun magnetic fields including their evolution, and the study of moving magnetic features and flux cancellation events in sunspots. The two problems will be investigated using coordinated observations of Hinode and four solar telescopes in Canary Islands. SOT onboard Hinode and solar telescopes in Canary Islands (SST, VTT, THEMIS, and DOT) will allow us to perform perform high precision spectro-polarimetric measurements in different spectral ranges (in the photosphere and the chromosphere), and imaging observations at the highest spatial resolution possible. All layers of the solar atmosphere will be covered from the photosphere to the corona, by means of XRT and EIS onboard Hinode.
