- FIRST ANNOUNCEMENT -
1. LEONID MAC WORKSHOP
April 12-15, 1999
NASA/Ames Research Center, Moffett Field, California
INVITATION
You are cordially invited to participate in an international workshop
at NASA/Ames Research Center to discuss the recent Leonid observing campaigns.
The Leonid meteor shower has offered unprecedented opportunity to address
outstanding issues in Planetary Astronomy, Astrobiology, and the dynamics of
the upper atmosphere.
This workshop aims to bring that science in focus, make a tally of
observational data from the recent November 1998 observing campaign,
and make recommendations for the next campaign in November 1999.
In particular, the workshop will discuss the first results from the
Leonid Multi-Instrument Aircraft Campaign and related ground-based efforts.
ABSTRACT AND REGISTRATION DEADLINE
- Abstracts are due: March 1, 1999
- Registration: February 20 for foreign nationals
March 1 for US nationals
Automatic registration and submission of abstracts is available at:

for life s origin on Earth
Related issues: Astrobiology, atmospheric and surface conditions on the
early Earth, formation of planetesimals.
14:00-17:00 Session on comet grain ejection and meteoroid stream dynamics
Related issues: the activity of the shower in 1998, Leonid meteoroid influx,
size distributions, and the satellite impact hazard.
17:00-18:00 News conference
17:00-20:00 Poster session and wine/cheese and buffet
Tuesday April 13
09:00-12:00 Session on meteoroid composition and ablation
Related issues: morphology and wake of meteoroids, organic matter in IDPs,
organic matter on planetary surfaces, composition of comets, evaporation of
silicates in proto-planetary environments.
14:00-17:00 Session on meteor-induced atmospheric chemistry
Related issues: meteor physics, shock and impact chemistry, flash
pyrolysis of organic matter, upper atmosphere composition and chemistry.
18:00-21:00 Group dinner
Invited presentation: "meteors and sprites"
Wednesday April 14
09:00-12:00 Session on physics and chemistry of neutral atom debris
and particles
Related issues: implications for the dynamics of the upper atmosphere,
sprites, meteoric signature of stratosphere aerosols, the ozone problem,
and iron catalysis of precursor molecules for life.
14:00-17:00 Plans and coordination for November 1999 Leonid MAC and
ground-based campaigns in the form of presentation reflecting past campaign
and future plans (including presentations of capacity available airborne
platforms) followed by working sessions along themes above
Thursday April 15
05:0-13:00 Site seeing tour
- balloon tour over Napa valley to commemorate historic balloon flight
in 1870 that viewed meteor shower above clouds
2. LEONID THREAT CONFERENCE
If you have not done so, do not forget to register for the Leonid Meteor
Storm and Satellite Threat Conference in Manhattan Beach, CA,
which is held between May 11-13, 1999. The conference focusses on
aspects of meteoroids and their effects on spacecraft.
