Description:
The primary requirements for observing the plumes are highest possible spatial and temporal resolution. For SOT, 2x2 summing (0.108 arcsecond pixels) suffices to resolve the plumes. Typical SOT cadence values used for past plume observations is 15???30 sec. Both EIS and TRACE see prominences in EUV absorption. Since the plumes are at the resolution limit of TRACE, unless they are bright in the 171and#197
or 195and#197
they will not be visible. For EIS, the plumes may be visible if they are bright or if they are seen in absorption against EUV loops in the background. EIS cadence should not exceed 30 seconds or the plumes may be too blurred by motion to be definable.
