Relation between CMEs and flares:

Historically, solar eruptions have been studied as a subject of flares. Coronal mass ejections became a topic of major interest since the seventies and grew rapidly over the past three decades. From a geoeffectiveness point of view, CMEs received the primary attention ("flare myth"), but from the initiation point of view, flares play an essential role. In fact, the view that flares and CMEs cannot be easily separated as independent phenomena is emerging in recent times, thanks to the imaging data in soft and hard X-rays from Yohkoh. RHESSI flare data can push this frontier further when used in conjunction with the white light and EUV data.

A related topic is tracing the origin of electrons fro interplanetary radio bursts. I am interested in connecting the Wind/WAVES radio data to the "dynamic spectrum" of low energy RHESSI photons to track the release of electrons spatially and temporally during eruptions. My experience with the radio (Clark Lake, VLA, Wind, and Nobeyama), X-ray (SMM, Yohkoh) and white light data (SMM, SOHO) will greatly enhance my participation in the RHESSI workshops.

I would like to look at the following events. These events were chosen based on type II bursts observed by Hiraiso Radio spectrograph and cross-checked with EIT/LASCO/RHESSI/Nobeyama. We can add other wavelength data such as TRACE, H-alpha...

(All times are approximate. We need to look around this time.)

Two other events ideal for our group:

All but two also have Nobeyama data.
