In this presentation, we will show some of our preliminary results. H-alpha jets are defined as dark features as seen from the far blue wing of spectroheliogram. We are interested in these features because they may result from small scale magnetic reconnection in the quiet sun region. An solar region approximately 120 arcsec x 95 arcsec centered at the coordinate 136E-400S was scanned repeatedly. We have totally 118 scans, each scan has 600 spectral images.
All images are flat-fielded and corrected for contrast variations due to optical effects.
By observing the evolution of selected features from movies complied from spectroheliograms, statistics such as life-time, size, and frequency of occurrence of selected features can be found. Combining these two approaches, we finally present the dynamic characteristics of H-alpha jets in comparison with other chromospheric features such as dark mottles, bright mottles, as well as filaments. A comparison with SOHO data will also be made. The 17 GHz NRO data had a time profile similar to GOES soft X ray light curves, except for a pair of short-lived spikes, which as a whole might imply events of impulsive injection of nonthermal particles amid gradual evolution of thermal particles during the flare. We verify such a scenario by tracing their counterparts at successively low frequencies available in OVRO data, eventually to identify the nonthermal component and separate it from the thermal component in space.
