The NRL's Very-high-resolution Advanced ULtraviolet Telescope (VAULT)
sounding rocket payload is currenlty scheduled for its second flight
from WSMR on October 25, 2001. VAULT is capable of obtaining
sub-arcsecond resolution (0.33 arcsec) images of the solar atmosphere
in the light of Ly alpha (70A bandpass).

The scientific objective of this flight is the investigation of
coronal heating processes at very fine scales.

The target will be an emerging (or otherwise active) region close to
disk center. The primary launch window is 17-18UT and secondary is
20-22UT but the actual time has not been verified by WSMR yet.

Support for this flight will be provided by TRACE, BBSO and
KPNO/SP. We will be very interested in high-res MDI magnetograms for
correlating the photospheric to the transition region evolution. We
also invite any other SOHO instrument to participate in the campaign.

TRACE will be the main collaboration and will determine the launch
time.

BBSO and KPNO/SP support is already confirmed and observation plans
will be included at a later date.

SOHO/EIT, will provide synoptic images in all four wavelengths close
to the launch time, probably both before and after.

SOHO/MDI will provide high-resolution magnetograms of the region as
close in time as possible to the flight, if it is possible to do so.
If not, then full-disk maps will suffice.

SOHO/CDS to make a mosaic using study GENE (ID 11, var 100). Rasters
should OVERLAP by at least 20''. Allow as much time as needed to fully
map the active region.

Local POC: G Lawrence, or other if more suitable
