EIT Observing Program:

Collaborative EIT Observations with the HRTS Sounding Rocket
Underflight

Investigators:

J.W. Cook and D. Moses (cook@hrts.nrl.navy.mil;
moses@louis14.nrl.navy.mil)

Brief Scientific Summary:

The NRL High Resolution Telescope and Spectrograph (HRTS) is
planned to be flown in the third quarter of 1996 as a sounding
rocket underflight of the SOHO spacecraft, to obtain UV spectra
over 1170-1700 A of chromospheric and transition region
temperature plasmas. These high spatial (1 arc sec) and spectral
(0.06 A) resolution spectrographic observations will provide a
link between the observations of SOHO and the chromospheric and
transition region phenomena studied over the past 20 years of the
HRTS rocket program. Of particular interest for EIT is the
comparison with the He II 304 A transition region observations.
Specific research topics include:

1) Comparison of explosive events observed by HRTS in the lower
transition region (C IV 1548 A at 10^5 K) to fine structures
observed by EIT in the upper transition region and corona.

2) Studies of the HRTS counterparts of the coronal and transition
region bright points observed by EIT (traditional XBPs, and EUV
bright points).

These observations will be used to pursue further the analysis
and suggestions for further work presented in Moses et al. (1994,
Ap. J., 430, 913) and Moses and Cook (1994, Space Sci. Rev.,
70, 81) to study transition region explosive events, XBPs, and
their relationship with small scale magnetic field evolution.


Suggested EIT Observations:

We would want observations at all 4 wavelengths, at highest
possible temporal cadence during an hour with the 5 minute rocket
flight at its middle. We would also want either groundbased
magnetograph observations (NSO/Kitt Peak), or SOHO MDI
observations, if appropriate. There may be problems connnected
with the SOHO scheduling because the actual sounding rocket
launch time can change at short notice, or the exact HRTS field
of view pointing could change from the planned, for many
uncontrollable reasons. The collaborative observation planning
details must be carefully arranged, but we have participated
successfully in such programs before.
