***************************************************************** 1. Information note for spacecraft operators on the Leonids 2000
From: W. Flury                e-mail:

Even though prediction methods and tools have been improved, there is still a 
considerable uncertainty on the magnitude of the 2000 Leonids apparition. Recent 
improvements are primarily in the timing of the event.It can be expected that the intensity of the  2000 event will be below that of 1999. 

ESA/ESOC will not sponsor real-time observation of the Leonids 2000. 

There is, however, no doubt that the Leonids, because of their enormous speed and 
kinetic energy, constitute a hazard to operational spacecraft.

2. AuroraWatch U.K. Web Site 
***************************************************************** From: Dr. Ian R. Mann         e-mail:

Dear Colleagues, 

I am pleased to announce the launch today of the AuroraWatch U.K. web site at
This site is devoted to monitoring geomagnetic activity over the U.K. in real-time, using 
data from the U.K. Sub-Auroral Magnetometer Network (SAMNET). The site 
monitors a U.K. auroral index, based on the magnitude of magnetic variations away 
from a quiet day magnetogram at York (YOR). 

When the magnetic variations are very large, signifying a large geomagnetic storm in 
which aurora may be visible from the U.K., an automatic "aurora-alert"  e-mail is sent to subscribers to the AuroraWatch U.K. e-mail list. Using Genie, this e-mail alert can' 
also be forwarded to mobile phones. 

The AuroraWatch U.K. web site also includes links to some relevant real-time 
solar-terrestrial physics data sources, and includes an explanation of the likely 
precursors of large geomagnetic storms. 

The site also aims to explain the northern lights to a lay audience, and includes a 
description aimed at the public understanding of these phenomena, as well as a guide to building your own simple "aurora detector"  magnetometer. The back page of todays 
Guardian Education section contains an article which explains the aurora to the public 
(spot the "interesting" Earths magnetic field and map of northern Europe!) and mentions our site. 

Any comments on you may have on the AuroraWatch U.K. pages would also be 

***************************************************************** 3.Info on European Space Weather Assets and Resources
***************************************************************** From: A. Hilgers                    e-mail:

Dear colleagues, 

I would like to draw your attention on useful source of information on European Space weather Assets and Resources, 

1/ Space Weather Information Server: 

Database developed under ESA contract by FMI. There is a search form from which 
one can explicitly restrict the search to European resources:

Please help to update this database by indicating new web sites. 

2/ Space Weather Euro-News database: 

Go to the page:

Type in your key words and at the end of your list add: +SWEN 
You will get all the relevant SWEN issues containing your key words.

***************************************************************** 4.Role of aeronomy in space weather 
***************************************************************** From M. Hapgood                        e-mail:

There is an interesting article on this topic on page 4 of the August 2000 issue of "The 
CEDAR Post", the newsletter of the US aeronomy community. You can download this 
from the CEDAR (Coupling, Energetics and Dynamics of Atmospheric Regions) web 
site on: 
The author argues that most (say 70%) space weather effects occur in the upper 
atmosphere but note that aeronomy is under represented in US scientific meetings and 
programmes concerned with space weather. He concludes that there is a need to raise 
the profile of the aeronomy community in US space weather activities. 

It would be interesting to see a debate whether this is also an issue in Europe - and, if 
so, to what extent. 

***************************************************************** 5.Survey of European Space Weather Resources
***************************************************************** From M. Hapgood                        e-mail:

The following note was previously circulated in SWEN Vol.4 Issue 15. 

The Rutherford Appleton Laboratory (RAL) is leading one of two parallel contracts 
that are studying the requirements for, and possible implementation of, a Space 
Weather programme within the European Space Agency. As part of that study, our 
team is building up a database of available and planned European space weather 
resources. The purpose of this note is to invite the operators of those resources to 
contribute information for the database. 
We would also be very happy to exchange information with other people working on 
this topic (subject to agreement from the information providers). 

The space weather resources that we will list include: 

a. instruments measuring space weather relevant parameters in the various space 
weather domains (Sun, heliosphere, magnetosphere, ionosphere/thermosphere and 
lower atmosphere). They will includeboth ground-based and space-based 

b. models that have the potential to convert space weather relevant parameters into 
other useful parameters, e.g. most importantly this includes spatial interpolation and 
predictions linking dfifferent space weather domains, also predictions in time. 

c. infrastructure providers that might support a space weather programme, e.g. satellite ground-stations. 

If you would like to submit information on a particular resource, please send the 
following information by Email to Mike Hapgood (Email: 

1. A short description of the resource: 

a. for instruments - the space weather domain studied, the instrument location and type of measurement. 

b. for models -  the space weather domain modelled, the form of modelling (e.g. 
physics-based or statistical) and a short description of the modelling technique 

c. for infrastructure - the type of infrastructure (ground station, data centre, etc) 

2. The name and address of the operator/owner. 

3. Whether the resource is operated/owned by a European organisation, National 
agencies, academic organisation, private industry,government-owned industry, etc. 

4. A web address to information about the resource 

5. If you are happy for this information to be passed to other interested parties. 

Please could I ask you to pass this note to any colleagues who you think may be 
interested to contribute but who don't get this newsletter. 

If you have any queries on this or any other aspects of our study, please contact the 
study manager, Mike Hapgood (Email:
