Quiet Sun Workshop
EVENTS OF INTEREST:
DATA SETS USED:
ANALYSIS UNDER TAKEN:
- 19 June 1998 - SUMER (Si IV, OIV), TRACE (C IV, Fe IX) and MDI
RELEVANT PREVIOUS WORK:
- Microflare structure and the underlying magnetic field
An analysis of the SUMER (Si IV, OIV), TRACE (C IV, Fe IX) and MDI
data from 19 June 1998 will be presented.
The SUMER data track the changes in line profiles from a single
narrow slice of quiet Sun network over a three hour period. The
field-of-view crosses several network cells and lanes where the underlying
field shows distinctly different geometry and evolution.
The emphasis will be on the relationship between high Doppler
shift events and the structure of the microflare emission in the
TRACE images and how they vary with changes in the complexity of
the underlying magnetic field.
I have also analysed the O IV line ratios and find what looks like
waves of compression and rarefaction continually moving across the
transition region. I would hope to be able to discuss the implications
of this finding and whether other shock signatures are noticeable in
the datasets at other wavelengths.
Another issue that I would like to discuss is whether we can determine the
height of the primary energy release. For example are transition region
brightenings a secondary effect due to energy release in the corona or
