H-alpha -300mA blue wing filtergrams 2. Fe I 6301.5 magnetograms 160x160"" FOV, 2x2 summed SP: Fast Map, 50"" scan over the AR, repeat every 30 minutes Programs 1 and
2 in the NFI can't be run at the same time so we'd run H-alpha for 2 hours and then switch to the Fe I magnetograms for another 2 hours. A cadence of 10 - 30 s for the BFI and NFI filtegrams would be adequate. AR moss is believed to correspond tothe ~ 1 MK footpoints of hot (3 MK) SXR loops and represents a sensitive monitor of coronal heating and conditions. Coronal loop models can run under certain circumstances into trouble when trying to reproduce the moss in that the predicted intensities are much larger than what is observed. Absorption of moss emission by cool and dense spicule plasma is a proposed mechanism for bringing observations and modeling into a better agreement.
