Summary of Minutes
from the IOPW meeting in Louisville, KY (Nov 11, 2004)
Committee members and affiliated meeting included Glenn Orton, Agustin
Sanchez-Lavega, Heidi Hammel,
Henry Roe, Karl Hibbits
The Jupiter/Saturn and Uranus/Neptune atmospheric groups met jointly at this
meeting.
Agustin Sanchez-Lavega, reporting for Jupiter and
Saturn atmospheres, discussed
successful tests of a new archive for IOPW atmospheres which would allow the
rapid access and comparison of many imaging files (jpeg) taken by amateur or
professional astronomers for Jupiter or Saturn. The archive
is at
is known as the Planetary Virtual Observatory and Laboratory (PVOL) for the
IOPW. Archiving is supported by R. Hueso.
The white oval remnant of the
3-white-oval merger, known as BA, is still present in
Jupiter. More data are
being acquired of the south polar region, with the
changing seasons.
Atmospheric sub-committee members discussed needs and approaches to support
Cassini atmospheric investigations. S. Perez-Hoyos and G. Orton discussed
variability of the south polar cap in the visible and infrared, respectively.
Heidi Hammel, reporting for Uranus and
significant number of Uranus atmosphere observations to be made in 2005 and
amateur alert networks.

Frank Marchis reports for the IOPW-satellite
subcommittee on activity in
2004-2005:
Monitoring the Volcanism of Io:
As often as possible (meaning when we have telescope time) we observed
Io with the Keck II Adaptive Optics system and its dedicated IR camera
(NIRC-2) between 1-5 microns. The weather conditions at
very bad during the winter and spring 2004 & 2005. We successfully
observed Io on
days in May 2004. In 2005, we recorded only one observation in Jan.
2005. An analysis of the 2003 and 2004 data was presented at the AGU
meeting (Marchis et al., 2004), two papers are in
preparation (PI: F.
Marchis)
Ourtbursts on Io:
We (PI: F. Marchis) obtained Target of Opportunity time
at VLT-8m to
observe Io when an ourburst occurs and nail down the
highest
temperature of the magma. Several instruments are used as an alarm
program, such as Lick-3m AO and IRTF (3-5 microns). This program was
initiated in 2004. No ourburst was detected yet.
JMEX: Jupiter Magnetospheric Explorer
JMEX is a small Explorer mission from NASA which has been selected for
flight. N. Schneider proposed to push for a ground-based campaigns
for
the mission (proposed launch in 2008). The specific needs fall into the
satellites, torus, aurora
& radio disciplines. Unfortunately, no
decision was taken for the Explorer missions and the program may be
canceled.
The IOPW-satellite web page was regularly updated in 2004.

Karl Hibbits volunteered to rotate off the steering
committee as discipline
leader for laboratory and theory. Paul Steffes
was suggested as a replacement
and agreed subsequent to the meeting to head this sub-discipline.
