H-alpha Doppler at +-0.8 Ang, with Ca II H interspersed. Cadence should be approximately 12 s for a set of three images, i.e., about 4 s between images. We can narrow the SOT FOV somewhat, so that we can maintain this cadence for at least one hour at a time. (Science-wise acceptable FOV would be similar to that ran by SOT with H-alpha Dopper on 27 Sep 2007, around 15:00.) Exposure times should be long: 600 ms for Ca, >400 ms for H-alpha. During periods when telemetry does not allow us to maintain such a high cadence, we would like Ca II H filtergrams at a lower cadence. We may switch the H-alpha Dopplergrams to +-0.41 Ang during runs later in the campaign period.
