1.   RAeS Space Weather Seminar
From:   Lesley Murphy

RAeS Space Weather Seminar

To be held at The Whittle Lecture Theatre, QinetiQ, Farnborough
Tuesday 30th October 2001, 09:30 – 16:00


The term ‘space weather’ is used to describe a number of physical phenomena in the 
space environment which can affect human beings and man-made technological systems 
on the earth or in space. One well-known but fairly benign example of a space weather 
effect is the aurora borealis or ‘Northern Lights’. Some other space weather effects have 
the potential to cause major disruption to technological systems such as power and
communication networks. As a result, the issue of space weather is not only of major
scientific interest but is also of great importance to a wide range of industries and 

The seminar will bring together some of the leading UK researchers in this field. 
Presentations will cover key topics such as space weather effects on mankind; 
radiation effects on spacecraft, aircraft and sea-level systems; solar proton effects; 
RF propagation effects; solar mass ejection phenomena; radiation belt dynamics; 
and Cluster observations of magnetospheric response to solar wind inputs.

The event is being hosted by QinetiQ and will be of interest to both scientific researchers 
and engineers working in the key areas of space weather phenomenology and effects 
on technological systems. It is hoped that the event will benefit participants not only by
providing an overview of current and recent developments in the field, but also by 
prompting discussion of some of the key areas for future research.


Expected speakers and their affiliations include: 
Dr. Andrew Coates (MSSL), 
Prof Clive Dyer (QinetiQ), 
Dr Steve Gabriel (Southampton University), 
Prof Paul Cannon (QinetiQ), 
Prof Richard Harrison (Rutherford Appleton Laboratory), 
Dr Richard Horne (British Antarctic Survey),
Prof Andre Balogh (Imperial College). 
The meeting will be chaired by Dr Eamonn Daly (ESA)
 and the keynote speaker will be Dr Paul Murdin.


Members and Visitors are Welcome, Limited number of places. 
Cover charge of £50.00 (members) and £70.00 (non members) is requested, 
this includes all refreshments and buffet lunch.  Entry ticket required.

This seminar has been organised by the Royal Aeronautical Society’s 
Space Group and will be held at QinetiQ (formerly DERA), Farnborough. 

Please apply to Susan Sims, Room G007, The Arthur C Clarke Building, 
QinetiQ, Cody Technology Park, Ively Road, Farnborough, Hampshire, 
GU14 0LX, telephone 01252 393944, Fax 01252 396335, 

Please make cheques payable to QinetiQ Ltd.  Receipt of cheque will 
guarantee booking. Further details will be sent with confirmation.

2. Space Weather: Research and Applications at the World Space Congress
From:  Eamonn Daly 

The World Space Congress, an event jointly organised by COSPAR and the IAF, 
will take place in Houston, Texas, USA, 10-19 October 2002.
There will be a joint COSPAR and IAC event on "Space Weather: Research and 
Applications" lasting two and a half days. This event will cover the scientific 
understanding of the space environment and the application of this understanding to
the environmental effects on space-based and ground-based systems. More details 
can be found at

3.  International Reference Ionosphere IRInfo No.22 September 20, 2001

IRI-2001 Software Update

Windows 2000 version of IRI-2001:

We are planning the development of a Windows 2000 version of the IRI-2001 software. 
This would include an interface for computing and plotting IRI parameters for user-specified 
conditions. Please let us know if you would be interested in a Windows version and would
encourage/recommend the development of the IRI Windows interfaces and software. 
(please do not REPLY to this message send your recommendation 

Software Updates and Corrections:

A number of corrections were implemented in the IRI-2001 code following the 
recommendations and suggestions of IRI users. The corrected files are now available 
from the IRI website at

We thankfully acknowledge the help of the following IRI users in finding and correcting 
these errors:
M. Torkar, Space Research Institute, Graz, Austria
P. Wilkinson, Ionospheric Prediction Service, Sydney, Australia
P. Webb, GSFC, Greenbelt, USA
E. Araujo-Pradere, University of Colorado Boulder, USA
D. Pesnell, GSFC, Greenbelt, USA

The most important correction concerns the new foF2 storm model. The internally found 
ap indices needed by this model were shifted by a day for the months March through 
December. Another error involved the misspelling of the variable 'lati', which led to 
incorrect D region electron densities when using the new Friedrich-Torkar model
(one of three options for the D region). Most other corrections involve time savings. 
All corrections are noted in the comments at the beginning of each program file. 
Specifically the following corrections were implemented:

C2001.03- 07/09/01 sdte(sdteh) instead of dte in ELTEIK call (P. Wilkinson)
C2001.03- 07/09/01 LATI instead of LAT1 in F00 call (M. Torkar)
C2001.04- 09/18/01 correct computation of foF2 for Rz12 user input
C2001.04- 09/19/01 Call APF only if different date and time (P. Webb)
C2001.03 09/07/01 APF: if(j1.eq.j2) -> if(IY.eq.j2) [P. Wilkinson,E.
Araujo]  ***ap correction ****
C2001.03 09/07/01 CONVER: LO2 = MOD(LO1,20)+1 [P. Webb,D. Pesnell]
C 2001.02 07/11/01 replace feldi(xi,h) by feldi (P. Wilkinson)
C 2001.02 07/11/01 variables EGNR, AGNR,OGNR not used (P. Wilkinson)

Several users had compiler-specific problems with the large block data statement of the 
iridreg.for file. This file is needed for the new D region model options. User who do not 
need to use these new options can work with the file irine.for (instead of irisub).

A slow down in speed was noted when using the new storm model. This is due to the 
subroutine apf that finds the necessary ap indices. Some user-provided improvements have 
been implemented.
