It would be important to obtain full-vector magnetograms, Dopplergrams, and LCT maps of the horizontal photospheric velocities simultaneously (during the given observational session). Specifically, obtaining FGs should be combined with Fast-map SP scans. The same FOV (164" x 164") is needed for both FG and SP observations. The following should be done in the time interval of the session (120 min): * SP fast scan aimed at obtaining a full-vector magnetogram; * Dopplerography at Fe 5576 A; * Imaging at 5576 A needed to carry out the LCT procedure and mapping horizontal velocities. During a session, 5576-A images and Dopplergrams should follow at a time cadence of 2 min. One SP fast-mode scan with a FOV of 164"x164" takes 31 min, and we would like to start running such SP scans every 40 min (in total, three SP fast maps for one session). If telemetry does not permit doing so, two SP maps for one session would be acceptable. It would be desirable to repeat such a session every 6 hours (2-h session + 4-hr interval) if telemetry permits. If sessions can hardly be repeated during a one-day interval, carrying out new session(s) on the next day and on some of subsequent days would be highly desirable. A very crude estimage of the data volume is as follows: * for the SP fast scan (3 maps (164" x 164") in one session), 930 Mbits/2h * for intensity mapping and Dopplerography at Fe 5576 A, 225 Mbits/2h (2min cadence, 2 wavelength positions, 164" x 164", 2 x 2 summing) Total: 1155 Mbits/2h If two SP fast scans with the FOV of 164"x164" are obtained for 1 session, the data volume will be 845 Mbits/2h in total (=620Mbits/2h for SP fast map and 225Mbits/2h for Dopplergram).;;The SOT is needed to implement the project.
