1. Space Weather Studies Final Presentations, ESA/ESTEC 6-7 December
From: A. Hilgers 

Announcement of Space Weather Studies Final Presentations, Newton room, 
6-7 December

The final presentations of the ESA space weather studies by the ALCATEL and RAL 
consortia will take place on 6 and 7 December 2001 at ESTEC, Noordwijk, the 
Netherlands. The consortia's presentations will be followed by a series of presentations
of ESA related activities. 

For the last 18 months, ALCATEL and RAL have been performing parallel studies of a 
possible future ESA space weather programme
. These studies were funded by the 
Agency's General Studies Programme. The studies have analysed user requirements 
and prepared analyses of space segment options and the ground-based "service segment".
This work has also been supported by an external Space Weather Working Team and 
by a study with the ESA Concurrent Design Facility (CDF).

Please note that the main purpose of these final presentations is to perform a thorough 
review of the contractors' work while more synthesized presentations of the work and 
more extended discussion of the future plans will take place during the Space Weather
Workshop of 17 to 19 December 2001
which you are also welcome to attend.

Please also inform interested colleagues in your area.

2. Magneto-Optical Filter (MOF)
From: Alessandro Cacciani

Magneto-Optical Filters (MOF) are in use at several institute around the world. One 
particular advantage of this technology for Space Weather applications is that it can 
allow measurement of solar magnetic fields (and/or Doppler fields) with a very compact 
and inexpensive instrument, so that it could be cloned and installed at several locations, 
even where there are not well-equipped observatories. To have a feeling of what a MOF
can do, please give a look at "". A MOF can work at high cadence 
(half a minute) and its dimensions are shown in the schematic drawing included on the 
web site ( 
The simultaneous measurement of full disk Doppler field and a possible set  up of a 
redundant network of identical instruments could be useful to monitor rapid magnetic 
and Doppler evolution of relevant Active Regions. I am interested to investigate the 
possibility to accomplish such a network in a collaborative effort among European institutes.

From: Paul Cannon 

Maastricht, The Netherlands, 17 to 24 August 2002.

The Local Organising Committee, through their Website 
and other outlets, are advertising the forthcoming General Assembly.

Phil Wilkinson (Commission G Chair) has also extracted some of this information to produce
further a site emphasising the Commission
G sessions and the Space Weather orientation of the meeting.

The deadline for receipt of on-line abstracts is January 15, 2002 and the deadline for the full
paper for the Conference Proceedings is 15 April, 2002.

4. Innovative Telescopes and Instrumentation for Solar Astrophysics
From: Sergey Avakyan

There will be a two day SPIE (The International Society for Optical Engineering) conference 
on "Innovative Telescopes and Instrumentation for Solar Astrophysics" as part of SPIE's 
International Symposium on Astronomical Telescopes and Instrumentation to be held 
22-28 August 2002 in Waikoloa, Hawaii. The solar conference is scheduled for the 22nd 
and 23rd. This conference will provide a forum for discussing planned solar telescopes and 
instruments and innovative ideas for the future for both space and ground. The conference
includes in particular the following topics of Space Weather Program: space observatories
and experiments (for example, resent results from solar telescopes in space - e.g., TRACE,
SOHO),imaging coronal mass ejections, imaging spectrometers, high resolution radio
spectrometers, high resolution (spatial and spectral) coronal studies, EUV/UV imaging, 
spectroscopy and detectors, cleanliness requirement for solar space missions. For further
information or to submit an abstract visit the SPIE web site at for information about the symposium in general and for information about the solar conference. 

Abstracts for the conference can be submitted on line and the deadline for submission is 
28 January 2002.
