Target: A Target of opportunity - a clearly visible cavity on the solar limb. The associated filament channel must be aligned so that the cavity is likely to remain visible between target selection and observations.
Time Window: We would like to observe promising cavities over a number of days for 4-6 hours at a time, centered around the prime MLSO observing time of 18-22 UT. This would allow us to model the quiescent cavity in three dimensions. In the case of cavity eruption we would observe changes associated with gradual onset of eruption.
