  2. PV Phase-I • Verify one observable or simple combination with typical wavelengths • for long duration (several hours – half a day) • Some of them can be carried out in the first light phase • as background observation Examples of FG observation sequences

  3. PV Phase-I Examples of SP observation sequences • SP observations can be carried out simultaneous with FG. • Some FG observables, especially magnetograms and Dopplergrams, • shall be carried out simultaneous with SP in order to check their performance.

  4. Filtergram observation Check item: - Orbital variation (focus, distortion, magnification) - Long-term image stability - Filter tuning speed, times for changing from each line to any other line - Image co-alignment between BFI, NFI, and SP Scientific objective: Photospheric and chromospheric structures BFI：50” x 100”(0.05”/pixel) NFI：80” x 160”(0.08”/pixel) Period: 0.5 day Target: AR (or QT) FOV：16” x 160” FG SP CH G-band Blue continuum Normal mapping - 4.8 sec/slit - 0.16”/1step 1.5 min/cycle 8 min/map Ca II H Ha continuum Ha line center Data rate: 0.3 Mbps (JPEG, 3bits/pix) Data rate: 0.3 Mbps (JPEG, 1.5bits/pix)
