1. March Solar Proton Event

****************************


From: Hugh Evans <Hugh.Evans@esa.int>, Piers Jiggens <Piers.Jiggens@esa.int>


Following a quiet period in February, March brought increased solar activity and with it the largest solar energetic particle event of cycle 24 so far! More information, including interactive plots of the GOES x-ray and proton fluxes, Integral IREM count rates and images from SDO/AIA (UV) and SOHO/LASCO (coronagraph), can be found at:

2. LYRA: An alternative flare monitoring service 

*************************************************


From: Marie Dominique <marie.dominique@oma.be>, Ingolf Dammasch <dammasch@oma.be>, David Berghmans <david.berghmans@oma.be>


From time to time, GOES suffers from interruptions of its soft-X-ray measurements, either because of technical problems or because it is transiting into the Earth shadow. Those interruptions have in a few occasions led to the non-detection of flares or to their misclassification. 


Such an example is illustrated on:

http://solwww.oma.be/users/dammasch/GoesLyra20110904.png

Around 06:00 AM, the peak of a C9.0 flare was missed by GOES, which therefore erroneously labeled it as C4.0. 


To deal with those (fortunately rare) situations, the SIDC at the Royal Observatory of Belgium (www.sidc.oma.be) has set-up an alternative for the GOES flare monitoring service, using the PROBA2/LYRA radiometer (http://proba2.sidc.be) as a GOES proxy.  More precisely, we use the two shorter wavelength channels of LYRA, namely the „aluminium‰ and „zirconium‰ channels. Those channels cover respectively the <5nm +17-80 nm range and the <2nm + 6-20nm range, meaning that they both include a soft X-ray and an EUV contribution. GOES flare scale, on the other hand, is computed from a channel observing in the 0.1-0.8nm and doesn‚t see the EUV.


To be able to use LYRA data as a proxy for GOES, we first have to remove the long-term EUV trend, which is done by subtracting the pre-flare level. Then, the aluminium and zirconium channels are respectively multiplied by 0.015 and 0.018, before to be added to the pre-flare value in GOES.


The result is illustrated on:

http://solwww.oma.be/users/dammasch/GoesLyra20120306.png

Both channels of LYRA produce similar results. The remaining differences between GOES and LYRA curves are still explained by the presence of EUV signal in LYRA channels. Because of this EUV contribution, the LYRA flare profiles usually peak slightly after GOES and the flares decay much slower. Nevertheless, the flare intensities deduced from LYRA data match quite well the ones of GOES.


Those curves are produced daily and currently available on:

3. FIRST ANNOUNCEMENT: Chapman Conference on Fundamental Properties and Processes of Magnetotails, Reykjavik, Iceland, March 10-15, 2013

*****************************************************************************************************************************************


From: Andreas Keiling <keiling@ssl.berkeley.edu>, Caitriona Jackman <caitriona.jackman@ucl.ac.uk>, Peter Delamere <delamere@colorado.edu>



The International AGU Chapman Conference on "Fundamental Properties and Processes of Magnetotails" will be held in Reykjavik, Iceland, from March 10th through March 15th, 2013. As the conveners, we invite you to participate in this meeting. 

Spacecraft observations have established that all magnetized planets in our solar system interact strongly with the solar wind and possess well-developed magnetotails. Magnetotails are the site for many dynamic processes critical to the circulation of mass, energy and magnetic flux. The great differences in solar wind conditions, planetary rotation rates, ionospheric conductivity, and physical dimensions from Mercury‚s small magnetosphere to the giant magnetospheres of Jupiter and Saturn provide an outstanding opportunity to extend our understanding of the influence of these factors. Therefore, this Chapman conference will provide a forum in which various communities can come together and discuss recent achievements of observational, theoretical, and modeling studies with the objective to develop a deeper understanding of fundamental properties and processes of planetary magnetotails through a comparative examination.


To build up a full picture of small- and large-scale dynamics, the Chapman conference will address various aspects of planetary magnetotails (including Mercury, Earth, Jupiter, Saturn, Uranus, and Neptune):


1. External Drivers*

2. Internal Modes**

3. Inner Coupling***


*(e.g., solar wind-magnetosphere coupling, IMF control, viscous processes, reconnection)

**(e.g, convection, fast flows, dipolarization, injections, centrifugal driver, fluxtube interchange, instabilities)

***(e.g., magnetotail-ionosphere coupling, coupling to the inner magnetosphere, current systems and closure, ion outflow effects)


The conveners are: Andreas Keiling (UC Berkeley, USA)

Caitriona Jackman (University College London, UK)

Peter Delamere (University of Colorado/LASP, USA)



The program committee includes: Colin Forsyth (MSSL, UK)

Denis Grodent (University of Liège, Belgium)

James Slavin (University of Michigan, USA)

Jin-Bin Cao (Beihang University, China)

Larry Kepko (NASA/GSFC, USA)

Mervyn Freeman (British Antarctic Survey, UK)

Michelle Thomsen (LANL, USA)

Norbert Krupp (Max-Planck-Institute, Germany)

Tsugunobu Nagai (Tokyo Institute of Technology, Japan)

Xianzhe Jia (University of Michigan, USA)



Further information concerning the venue, registration and conference website will be announced in future issues of the SWEN Newsletter.
