Dates: 2017/10/02-2017/10/15, 2016/09/23 - 2016/10/06 Time window: The best coordination time is from 8:45 am to noon La Palma time, which is 07:45 UT to 11 UT. During this La Palma time (7:45 to 11 UT), IRIS will focus on high cadence runs, such as sit-and-stare, small or medium rasters. A single target will be chosen for each dayfs observing in this time period. The IRIS planner and SOT CO would typically schedule large raster scans for context before or after the La Palma time, so that high cadence programs are run during La Palma time.
Every day from 11 UT to 17 UT, IRIS and SST will perform flarewatch on the most promising active region. Hinode is invited to do the same using its standard flarewatch programs.
Target(s) of interest: A. Chromospheric Heating: AR mossy plage is first priority, then QS network
B. RBEs/RREs/Jets: strong network close to disk center, mu > 0.9, IRIS slit should ideally be positioned just next to the magnetic network regions, crossing the chromospheric halo and covering jets shooting off from the network.
