 abstract of observational proposal

SUMI will obtain 5 minutes of Mg II and C IV spectra and slit-jaw images, as well as Stokes information in those lines. The spatial resolution will be of order 1 arcsec. Targeting will be an active region if it is present, and TBD by Jonathan and colleagues if it isn't. These unique measurements provide an excellent opportunity to study the connection between the chromosphere and TR (along the lines of what IRIS and Solar C will do), as well as study the magnetic field properties in the upper chromosphere and low TR.

Current launch window (LW) for SUMI is 18:55-19:55 UT on July 5 but with a launch time that will be known to 5-10 minutes precision two to fours days in advance. SUMI will attempt to avoid the time periods that Hinode passes through the SAA. For timing reference, we use:
LWB=18:40 UT, July 5
LWE=20:15 UT, July 5

 request to SOT
Before LWB: - High resolution SP-scan of whole AR ending at LWB.
                - At the end of this scan (from LWB-5 min to LWB):  
        BFI/Ca and G-band images over full FOV
        NFI/Na IVDG over full FOV, 2x2 binned
From LWB to LWE:
                SP : fast raster (dynamics), 15"x60" at 1 min cadence, 2x binning and exposing at every other slit position
                NFI: H-alpha sequence: H-alpha at -2.1A, at -1.28A and
                     -0.87A, 30"x82", 2x2 rebinned, at 13 s cadence
                BFI: Ca II H, 38"x88", 2x2 rebinned, exposure time
                     of >0.6s, at 13 s cadence

The NFI high cadence run is similar to that of HOP 159, which was run on April 25 2010 and Sep 17 2010.
The SP fast raster is similar to what was run for SUMI first launch (HOP 77) on July 30, 2010.

After LWE: - High resolution SP-scan of whole AR starting at LWE.
              - At the beginning of this scan (from LWE to LWE+5 min):  
        BFI/Ca and G-band images over full FOV
        NFI/Na IVDG over full FOV, 2x2 binned

Telemetry rate:  XX Mbits/hour

 request to XRT
LWB to LWE: Images with Al poly filter configuration at 30 s cadence with AEC exposure for a FOV of 384"x384".

NOTE: Pointing offset by (+64", - 20") from usual SOT alignment to match NFI's optimum resppnse area

Telemetry rate:  XX Mbits/hour

 request to EIS
Ending at LWB: EIS study 373 (VHH_SlowAR_2h20_DPCM), which rasters a 256"x256" region with 60s exposure time for a range of lines that allow study of line asymmetries for a range of temperatures. Many of these lines have been selected to allow clean measurements of the blueward asymmetries associated with the upflow events (i.e., no known blends, or weak blends).

LWB to LWE: EIS study 436 (VHH_HI_BRT_SCAN_EXT), which rasters a 16"x240" region with 25s exposure time and a 2" slit for the same lines as the large raster.

After LWE: EIS study 373

Telemetry rate:  XX Mbits/hour
