1. IAGA Working Group V-2 Questionnaire Regarding Use of Geomagnetic  Indices
From:  Richard Holme

Geomagnetic Indices are provided on time scales, varying from real time
estimates, through quick look (1-2 days after), half-monthly (e.g., Kp),
preliminary, to definitive (often several years later - e.g., Dst).
Increasing effort is being devoted to providing real-time services,
but there is generally a trade-off between speed of deliverability and
accuracy. We are also concerned as to whether the indices currently
available really do meet user's needs (for example, 3 hour range 
indices such as the K and aa might be used when what is really needed 
is an index that is a direct measure of rapid transient variations).

In order to collect input on these issues, we have developed a
questionnaire which may be found at the following link:

Could you please take a few minutes to complete this questionnaire ?
If you make multiple uses of indices, please submit a separate response
for each use.

Thank you for your help - we are very grateful for any information you 
can contribute.

2. Reports from ESA Space Weather programme study
From: Mike Hapgood

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 announced in previous issues of SWEN, the reports from this 
study are gradually being released into the public domain. Please see for a list of 
the reports now publicly available.

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

3. Establishment of Chinese-Russian Joint Research Center on Space
From: Jinbin CAO

In December, 2000, one delegation of Chinese Academy of Sciences on
space weather visited the Solar Terrestrial Physics Institute of
Siberian Division of Russian Academy of Sciences. The two sides agreed
to establish Joint Research Center on Space Weather and enhance the
cooperation research and data exchange in the area of space weather. 
The first Russian-Chinese Workshop on Space Weather was hosted in Solar
Terrestrial Physics Institute of Siberian Division of Russian Academy
of Sciences, from 14-19 December, 2000, Irkutsk, Russia. The second
Chinese-Russian Workshop on Space Weather will be hosted by
Chinese-Russian Joint Research Center on Space Weather from September 
13 - 14 2001, at Space Conference Center of Center for Space Sciences 
and Applied Research of Chinese Academy of Science, Beijing, China.

4. Post Doc. position for Cluster Science in Norway
From:  Bjoern Lybekk

The four Cluster II satellites were launched mid 2000 and were ready 
for full operation at the beginning of 2001. Three groups in Norway 
are involved in Cluster II experiments. The University of Oslo takes 
part in the electric field and wave experiment (EFW), the University 
of Bergen in ion and electron experiments covering energies from 25 keV 
to 1 MeV (RAPID), and the Norwegian Defence Research Establishment 
takes part in two different experiments, one to measure electrons from 
a few eV to 20 keV (PEACE) and another where the objective is to reduce
positive satellite potentials by emitting high energy ions (ASPOC).
The three groups cooperate and are jointly supported by the Research 
Council of Norway. In the years to come the groups will direct a 
substantial part of their resources to Cluster science and to research 
on combining space and groundbased observations over Northern 
Scandinavia and Svalbard. There is also ample opportunities to cooperate
 with all European and US groups involved in the Cluster II programme.

As a part of this research effort the Research Council of Norway has 
funded a two-year post doc. position within the Norwegian Cluster II 
programme. The position is open at the locations of the three Norwegian 
Cluster II groups. The final decision on location will depend on the 
successful candidate's background and interests in pursuing Cluster II 

Further information can be obtained from Professor Finn Soraas,
Department of Physics, University of Bergen, 
Professor Jan Holtet, Department of Physics, University of Oslo
 or Dr. Knut Svenes, The Norwegian Defence
Research Establishment.

Application, including an outline of the applicant's scientific interests
within the Cluster programme, should be submitted to The Department of
Attn. J. Holtet, University of Oslo, P.O. Box 1048 Blindern, N-0316 Oslo,
Norway, before August 15, 2001. The application should also include 3 
sets of copies of the applicant's 5 most significant publications and 
a summary of the importance of these works.

5. International Reference Ionosphere; IRInfo No.20; June 19, 2001
From: Dieter Bilitza

IRI-2001 Now Available from NSSDC

The International Reference Ionosphere (IRI) is a joint project of
the Committee on Space Research (COSPAR) and the International Union
of Radio Science (URSI). The newest version of this international
standard is now available from the models archive of NASA's National
Space Science Data
Center (NSSDC) at
Ftp to with anonymous as username and email
address as password, cd models,
cd ionospheric, cd iri, cd iri2001, cd fortran_code. Please consult
00readme.txt file for download options.

A large number of improvements, new parameters, and new options have 
been incorporated into this latest version. The most important changes 

(1) Two new options for the D region electron density: (a) The model
developed by
Friedrich, Pilgram, and Torkar (Adv. Space Res., in press, 2001) at
the Technical
University, Graz, Austria. Their model interpolates in a data base of
all available
and reliable rocket data. (b) The model developed by Danilov, Rodevich,
and Smirnova (Adv. Space Res. 15/2, 165, 1995) at the Institute of
Applied Geophysics,Moscow, Russia. Their model includes predictions 
for Winter Anomaly conditions and for times of Stratospheric Warming.

(2) A much better representation of the electron density in the
region between E
valley and F2 peak based on the work performed during an annual IRI 
Task Force Activity at the Abdus Salam International Center for 
Theoretical Physics (ICTP) in Trieste, Italy organized by S. Radicella
(ICTP) and focusing primarily on the low latitude region (Radicella, 
Bilitza, Reinisch, Adeniyi, Mosert, Zolesi, Zhang, and Zhang, Adv. 
Space Res.22/6, 731, 1998; Reinisch and Huang, Adv. Space Res. 25/1, 81,
1999; Bilitza, Radicella, Reinisch, Adeniyi, Mosert, Zhang, and Obrou,
Adv. Space Res. 25/1, 89, 2000).

(3) Inclusion of the stormtime updating model for the F2 peak density
that is a result of the work of Fuller-Rowell, Araujo-Pradere and 
Codrescu (Adv. Space Res.25/1, 139, 2000) at the Space Environment 
Center, Boulder, Colorado. The changes in density are predicted on the 
basis of the ap magnetic index for the preceeding 30 hours. The IRI
software finds the required ap indices internally from an ap index files 
that is now included with the software distribution.

(4) The model of Truhlik, Triskova, Smilauer, and Afonin (Adv. Space 
Res. 25/1,163, 2000) developed at the Institute of Atmospheric Physics
in Prague, CzechRepublic was included as a new option for the electron
temperature. Their model is based on data from three Interkosmos 
satellites and uses a latitudinal parameter that is closely tied to 
the magnetic field geometry.

(5) The ion drift model developed by Scherliess and Fejer 
(J.Geophys. Res. 104, 6829, 1999) at Utah State University is now 
part of IRI. The model describes the F region vertical ion drift 
at the magnetic equator, a parameter of primary importance for all 
studies of the equatorial ionosphere.

Since these additions have led to a considerable increase in the size
and required CPU time, it was decided to also include a special version 
for users that are only interested in the IRI electron density above 
the D-region and the total electron content (TEC). The reduced version 
is recommended for all applications that require only electron density 
(above 100 km) or TEC. We are now in the process of including these changes
also in the IRI web interface that lets users list and plot IRI parameters 
for specified specified input conditions.
