NAM 2017: Call for abstracts on “The Physical Processes Underlying Space Weather”

We invite abstract submission for the National Astronomy Meeting 2017 session “The Physical Processes Underlying Space Weather: Formation, Eruption and Propagation of Coronal Mass Ejections”.  

The aim of the session is to bring together solar and heliospheric physicists, both modelers and observers, to discuss the formation and evolution of magnetic flux ropes with particular focus on:

  1. what are the universal physical mechanisms responsible for triggering solar eruptions,
  2. how and when magnetic flux ropes are formed,
  3. how their structure evolves during their propagation through the inner heliosphere,
  4. how the structure of the interplanetary magnetic clouds relate to their source regions on the Sun.


The NAM 2017 will be hosted at the University of Hull (UK) during the 2nd-6th July 2017. We note that this is shortly before the IAU Symposium on Space Weather of the Heliosphere in Exeter (UK), and that this perhaps provides an opportunity for colleagues from further afield to combine two meetings.

Please note that the deadline for abstract submission is April 14, 2017.

Identification of the different magnetic field contributions during a geomagnetic storm



We announce to the community a recently published paper on the identification of the different magnetic field contributions during a geomagnetic storm in magnetospheric and ground observations. The authors of the paper are SWICo members  from different institutions.

Link to the paper




We investigate the time variation of the magnetospheric and Earth’s magnetic field during both quiet and disturbed periods. We identify the timescale variations associated with different magnetospheric current systems, solar-wind–magnetosphere high-frequency interactions, ionospheric processes, and internal dynamics of the magnetosphere. In addition, we propose a new local index for the identification of the intensity of a geomagnetic storm on the ground.

Spatial interactions in a modified Daisyworld model

We point out to the community an interesting paper by the UNICAL group on a modified version of the Daisyworld model. First author of the paper is the SWICo member Tommaso Alberti.

Link to the paper


We investigate a modified version of the Daisyworld model, originally introduced by Lovelock and Watson to describe in a simple way the interactions between an Earth-like planet, its biosphere, and the incoming solar radiation, where spatial dependency, variable heat diffusivity, and greenhouse effect are explicitly taken into account.
In this way, we obtain a more realistic energy-balance model to investigate the evolution of the Earth’s climate by considering several influencing factors.

The model is based on a hypothetical planet, like the Earth, which receives the radiant energy coming from a Sun-like star, and is populated by two kinds of identical plants differing in their color: white daisies reflecting light and black daisies absorbing light. The interactions and feedbacks between the collective biota of the planet and the incoming
radiation form a self-regulating system where the conditions for life are maintained.

We show that the diffusion process is able to destabilize the system and plays an important role in setting the symmetry with respect to the equator. The greenhouse effect, modeled through a grayness function, affects the temperature evolution and contributes to self-regulating the planet climate, in agreement with observational data analysis.

The equilibrium state is significantly dependent on the initial conditions. The initial conditions of daisy
coverage influence the vegetation profiles although they do not significantly modify the temperature behavior. This implies that a different surface coverage by oceans, ice and vegetation can locally change their interactions, producing local micro-climate (similar to the climatic zones).
This model could be very useful in the framework of climate changes, due to its simplicity, to provide both global and local informations about temperature and biosphere changes.

Les Houches school of plasma physics announcement


From laboratories to astrophysics: the expanding universe of plasma physics
Les Houches school of physics

Plasma physics plays a central role in many natural and man-made systems, from the vicinity of black holes to fusion experiments. This area of research is in fast development thanks to the strong interplay between experimental, theoretical, and numerical approaches. Long-standing challenges such as magnetic reconnection, turbulence, shocks, dynamo processes, or particle acceleration can now be tackled directly by a combination of these techniques. The goal of this school is to gather students and researchers from various communities (astrophysics, applied mathematics, fluid dynamics, fusion research) to provide a unified framework of plasma dynamics and to exchange new theoretical and experimental developments between these communities.

Session dates: May 1-12 2017

Post-doctoral Researcher Position at the ISSI


Post-doctoral Researcher Position at the International Space Science Institute, Bern, Switzerland

The International Space Science Institute (ISSI), Bern, Switzerland is seeking to appoint a post-doctoral researcher for 2 years primarily to work on a Horizon 2020 project, MiARD, the Multi Instrument Analysis of Rosetta Data. The post will involve two main strands, namely:

  1. Assessment of the potential dangers to interplanetary spacecraft from cometary dust through the use of existing models such as ESA’s “Interplanetary Meteoroid Environment Model” (IMEM) by the updating of such models with new information derived from Rosetta data.
  2. Study of the development of gas and dust activity triggered by different volatiles when comet 67P was approaching the Sun through the analysis and interpretation of data from various Rosetta instruments.

These activities will involve working with collaborators at partner institutes in Switzerland, France and Germany and with staff at ISSI. The successful candidate will ideally have experience of relevant aspects of cometary science with most likely a background in planetary science, physics, chemistry or related subjects. A small amount of time will also be available for the candidate’s personal research. Involvement in ISSI’s programme of activities would also be possible (details at This position is available for an immediate start. Salary and conditions of employment will be similar to those provided by the Swiss National Science Foundation.
The application should include a motivation letter, the curriculum vitae, the list of publications and the names, addresses and means of contact of three references, not exceeding 7 pages in total. It shall be addressed to ISSI, attn. Professor John Zarnecki, Hallerstrasse 6, CH-3012 Bern, Switzerland; email: and with copy to: Professor Rafael Rodrigo; email:

Submissions by email are preferred provided all the documents are in the form of a single PDF file.

All applications must be received by ISSI no later than January 31st, 2017.
