10. Search for Brightness Variations in Fe XIV Coronagraph Observations of the Quiescent Solar Corona

Abstract

We use Fe XIV5303 Å green line images obtained by the Large Angle Spectrometric Coronagraph (LASCO) on board SOHOto search for variability in the quiescent solar corona in the shortest observable timescales. The observing program obtained Fe XIVimages of a small area of the inner corona every 2 minutes over a period of 1 hr. We present results from two executions of this program taken several months apart. The most obvious variability observed in the two sequences is in the form of quasi-steady brightening on timescales of at least an hour. Of particular interest are two compact loops that are observed to vary significantly during the course of the observations. Superposed on the long-term brightening in these loops are statistically significant variations on timescales of about 30 minutes. In both loops, the overall brightening is greatest at the apparent loop tops, where the intensity increases by at least 25%. In one loop there appears to be a flow up one of the legs of the loop. We place these observations in context with earlier observations of coronal variability, and we discuss the energy requirements for the observed brightening. Emission measures computed from Fe XIVintensities measured within the two brightening loops are over an order of magnitude lower than those typically found for active regions on the solar disk, which suggests significantly lower average densities. For one of the loops, we measure densities in the range ne= (5.0-7.4) × 108cm-3. Lower than average densities are expected for the two loops, given that they reach more than 1 pressure scale height above the solar limb.
