Seminar on Solar Storms, London, UK



The UK Institute of Engineering and Technology (IET) will host a Seminar on Solar Storms in London, 30th April 2013.


What’s it about? – "[...] the scientific consensus is that the threat is real and that we need to take action immediately because we have no idea when the next big one might strike." (Source: Earth magazine)

Terrorism and natural disasters might be at the forefront of the minds of policy makers and the global population, but a significant threat lurks over our heads: the sun. A massive solar storm, of a size last seen a century and a half ago, could easily leave hundreds of millions of people in the dark for days, weeks or even months. (Source: Earth magazine)

Chair and Keynote Speaker, Prof Mike Hapgood, RAL says "Good engineering design must be the first line of defence against space weather."

Reasons to attend

  • Understand the scale and frequency of solar storms
  • Appreciate the challenge you face to protect your ground based assets and infrastructure
  • Derive essential knowledge to help build your business case to protect engineered assets and systems
  • Meet the people who can simulate effects of solar storms and give you essential insight into your equipment and systems resilience
  • Gather insights into effects of CMEs on the power grid and apply this learning to your systems
  • Learn what protective steps can be taken to protect your assets from failure to perform on demand
  • Rub shoulders with government advisors to understand solar storms upon the National Risk Register
More information about the event is available on-line.

EISCAT_3D User Meeting, 6-8 May, Uppsala

The 5th EISCAT_3D User Meeting will take place at the Ångström Laboratory in Uppsala, Sweden, 6th to 8th May, 2013.

The up-to-date programme is available on-line. The three days of the meeting will focus on the following major topics:
  • Monday: Special Topic (Data Analysis and Management) and EISCAT_3D
  • Tuesday: General EISCAT and EISCAT_3D Science: New results and future plans
  • Wednesday: EISCAT_3D Preparatory Phase Project: status, site selection. Discussion of future actions by the user community

Please register as soon as possible. Traditionally hotel room availability in Uppsala at this time of the year has been tight, and thus we recommend you reserve a room as first priority.

Vacancy: PostDoc in Plasma and Space Physics, Oslo, Norway

A position as postdoctoral research fellow in Plasma- and Space Physics is available at the Department of Physics, University of Oslo, Oslo, Norway.

The University of Oslo is searching for a physicist with a numerical modelling background, to calculate scintillations in GNSS signals due to in-situ observed F-region plasma irregularities by sounding rockets.

The announced position is associated with the group of plasma- and space physics and their STAR-initiative ("Space Technology And Research development centre") for a fixed period of 2 years. STAR is in charge of a sounding rocket program that takes advantage of the research infrastructure in Svalbard (optics, radars, GNSS scintillations) to study plasma waves, instability processes and turbulence in the F-region cusp/polar cap ionosphere. STAR also contributes to magnetospheric and planetary missions.

The STAR group developed a novel Langmuir probe system for the Investigation of Cusp Irregularities (ICI) series of rockets, to measure absolute electron densities down to meter scales. The instrument is miniaturised and will also be used on several cubesat missions to be in orbit in 2014-2015 (CubeSTAR and QB50).  The main goal of the current project is to verify that real time measurements of F-region plasma structure irregularities may lead to determinations of the resulting position uncertainties for the GNSS users on ground. The main part of the project will be to develop a software model to calculate the amplitude and phase fluctuations in the received radio signals on ground, based on the rocket observations of F-region irregularities. During the project period we will have two rocket flights to test the predictions from the model with GNSS ranging errors observed on ground.

Applicants must have a Ph.D. in physics or equivalent experience in a relevant area (e.g. radio science, scientific use of GNSS receiver systems, classical theoretical background on wave propagation in an inhomogeneous medium, experience in phase screen techniques, or other relevant experience). The candidate must have demonstrated strong programming skills for advanced data analysis and visualisation techniques. A good command of English is required.

More details on the project and application can be found at: http://uio.easycruit.com/vacancy/929700/64282?iso=no.

Deadline for application is 19th April 2013.

EISCAT Peer-Review Programme: Radar Time Available for Anyone

The EISCAT Scientific Association invites applications for observing time on the EISCAT facilities in 2013, by individual scientists, research groups, and consortia throughout the world on equal, competitive basis. This means that anyone can apply, independent of whether or not the applicant is from an EISCAT associate country.

While evaluations are merit based, in the case of two applications having similar merits in evaluation, preference will be given either to those applicants who are new to the EISCAT facilities, in order to enlarge the EISCAT user community and further more open access to the facilities, or to the applicant showing stronger educational impact in their proposal.

EISCAT is aiming to establish closer ties with the users of incoherent scatter radars (ISR) worldwide and bring in new users, young scientists, postdocs, and students who have not used the EISCAT facilities in the past.  The EISCAT International Symposium, which will take place 12th to 16th August 2013, will also aim to reach similar goals of bringing ISR users from around the world to interact more closely and collaborate.

The present call is the second call for 2013. In total, 200 hours of experiment time are open for international, peer-reviewed competition, and are available for the use of any of the current EISCAT facilities. Roughly half of this time has been allocated during the first call.

Please refer to EISCAT's pages on the Peer-Review Programme and in particular to the definition of the call for more information.

The deadline for proposals is 1st May 2013 at 24:00 UTC.
