Updates to the GEM Storms Web Pages
-----------------------------------
From: Geoff Reeves (reeves at lanl.gov) 

The GEM Inner Magnetosphere Storms web pages have recently been 
updated with new material.

The GEM Storms web pages are at
http://leadbelly.lanl.gov/GEM_Storms/GEMstorms.html

New material includes:

1) Local time maps of the ground magnetic perturbations at mid- and 
low-latitudes. These maps show the ground-level magnetic response to 
the asymmetric ring current as well as the effects of the substorm 
current wedge near midnight.

2) Plots of the Polar Cap Index from Vostok at 1-minute resolution.

3) A "General Data Links" section that provides links to sites with 
data and summary plots that include, but are not specific to, the GEM 
Storm intervals. This includes the University of Alaska's 
magnetometer data.

4) AMIE-derived geomagnetic indices for the October 1999 storm. (Data 
for the other GEM storms was posted previously and is still 
available).

On behalf of the campaign chairs I would like to thank everyone who 
has contributed to this effort and I would like to encourage anyone 
else who would like to participate but has not yet done so to send me 
your material, your links, you interpretations, or anything else you 
would like to contribute.

Thanks for your participation
Geoff
