1. Request for Space Weather Forecasting Rules of Thumb


From: John Kennewell <jak AT>

     Phil Wilkinson <phil AT>

At the recent IUGG meeting in Melbourne, Australia, we presented a poster on Rules of Thumb for Space Weather Forecasting, and we would like to thank those of you who submitted such rules in response to email requests we sent to all space weather forecast centres (RWC's) around the world.

We will be publishing a follow-up paper in the journal:

History of Geo- and Space Sciences (HGSS)

We would encourage anyone who wishes to submit forecasting rules of thumb and who has not yet done so, to make a submission to either of us (email addresses above) within the next six weeks. We would be particularly interested in rules with a specifically local flavour.

Our suggested format is:

Category: (Solar, Geomagnetic, Ionospheric, Space Effects, etc)

Rule:    (brief but adequate description)

Source:   (if known, paper reference if available)

Acknowledgement:  (who should be given credit as the originator of the rule)

Submitter:  (if you wish credit as the submitter of the rule - as opposed to the originator - please supply credit details)

Thank you in anticipation.


2. Release of Plasmasphere Density model on the European Space Weather Portal


From: Stijn Calders <stijn.calders AT AERONOMIE.BE>

We are happy to announce the release of a new model on the European Space Weather Portal ( The Plasmasphere Density model is made by Dr. Viviane Pierrard and Kris Borremans of the Belgian Institute for Space Aeronomy (BIRA-IASB, Brussels - Belgium).

The 3D dynamic model of the plasmasphere provides the number density of the particles and the position of the plasmapause as a function of time (Pierrard and Stegen, 2008). The model is accessible through In the simulations presented on the European space weather portal, the user gives the date of the event as an input. The program retrieves the observed geomagnetic activity level index Kp and calculates the position of the plasmapause and the number density of the electron predicted by the model in the geomagnetic equatorial plane. The dynamics of the model is directly related to the convection electric field that depends on Kp. Animated simulations show the dynamical plasmasphere every half hour of the simulated day.

In the right side bar you see a nowcasting of the plasmasphere density which is rebuilt every hour and is using Pierrard's model and the IRF Kp forecast retrieved from SWENET. The model has been recently coupled to the ionosphere (Pierrard and Voiculescu, 2011). If you are interested in obtaining more information, please contact

If you have any model you would like to make publicly available at the European Space Weather Portal, please contact Stijn Calders ( 


3. Release of Solar Energetic Proton Fluxes Tools (SEPF)


From: Ingmar Sandberg <sandberg AT>

We are happy to announce the release of a new automated software tool for the monitoring of Solar Energetic Proton events fluxes. The SEPF (Solar Energetic Proton Fluxes) Tools uses measurements of ESA s Standard Radiation Environment Monitor (SREM). SREM currently operates on-board six European spacecraft (Proba-1, INTEGRAL, Rosetta, Giove-B, Herschel and Planck), and measures high-energy protons and electrons with a fair angular and spectral resolution.     

The SEPF tool is based on the automated implementation of the inverse method developed by the Institute for Space Applications and Remote Sensing of the National Observatory of Athens (ISARS/NOA), permitting the calculation of high-energy proton fluxes from SREM count-rates. Results of the method have been validated for selected number of past solar energetic particle events using measurements from other space-born proton monitors. The SEPF tool unfolds downlinked SREM count-rates, calculates the omnidirectional differential proton fluxes and provides results to the space weather community acting as a virtual multi-point proton flux monitor on a daily-basis. 

The first on-line version of the SEPF Tool is accessible at:
