A Summary of the SWIMMR Kick-Off Meeting

The kick-off event for the Space Weather Innovation, Measurement, Modelling and Risk Study (one of the Wave 2 programmes of the UKRI Strategic Priorities Fund) took place in the Wolfson Library of the Royal Society on Tuesday November 26th. Seventy-five people attended the event, representing a range of academic institutions, as well as representatives from industry, government and public sector research establishments such as the UK Met Office. 

The morning session of the meeting consisted of five presentations, introducing the programme and its relevance to government, the Research Councils and the Met Office, as well as describing details of the potential calls. The presentations were as follows:

  •  Prof John Loughhead (Chief Scientific Advisor to BEIS) - Space Weather Innovation, Measurement, Modelling and Risk Programme (a governmental perspective). The slides from Prof John Loughhead's talk are available here.
  • Prof Chris Mutlow (Director of STFC RAL Space) - SWIMMR: Project funded by the Strategic Priorities Fund (a perspective from STFC).  The slides from Prof Chris Mutlow's talk are available here.
  • Jacky Wood (Head of Business Partnerships at NERC) - Space Weather Innovation, Measurement, Modelling and Risk (SWIMMR) - A NERC perspective.  The slides from Jacky Wood's talk are available here.
  • Dr. Ian McCrea (Senior Programme Manager for SWIMMR) -  SWIMMR: Space Weather Innovation, Measurement, Modelling and Risk: A wave 2 programme of the UKRI Strategic Priorities Fund.  The slides from Dr Ian McCrea's talk are available here.
  • Mark Gibbs (Head of Space Weather at the UK Met Office) - SWIMMR (Met Office perspective and detailed description of the calls.  The slides from Mark Gibb's talk are available here.

During the lunch break, the Announcement of Opportunity for the five NERC SWIMMR calls was issued on the NERC web site.  The afternoon therefore began with a brief introduction by Jacky Wood to the NERC Announcement of Opportunity, and the particular terms and conditions which it contained.

The remainder of the afternoon session was spent in a Question and Answer session in which attendees were able to ask questions to the speakers about the nature of the programme and the potential timing of future calls, and finally to an informal discussion session, in which participants gathered into groups to discuss the opportunities for funding which had been outlined.

Outcome of SSAP priority project review

From the MIST mailing list:

We are writing to convey the outcome of this year’s priority project “light touch” review, specifically with reference to those projects within the remit of SSAP. We would like to thank all the PIs that originally submitted ideas, and those who provided updates to their projects over the summer. SSAP strongly believe that all the projects submitted are underpinned by strong scientific drivers in the SSAP area.

The “light touch” review was undertaken with a unified approach by SSAP and AAP, considering factors that have led to priority project development (in STFC or other research councils) or new funding for priority projects (1/51 projects in the STFC remit) in the last 12 months. After careful discussion, it was agreed by SSAP and AAP not to select any project where the remit clearly overlaps with UKSA (i.e. space missions or TRL 4+), reflecting STFC’s focus on ground-based observations, science exploitation and TRL 0-3 development. Whilst in no way reflecting the excellence of the science, or community scientific wishes, this approach has resulted in some changes to the list of SSAP priority projects. However, now, unlike at the time of the original call, it is clear that such projects cannot move forwards without UKSA (financial) support, and such funds are already committed according to UKSA’s existing programme. SSAP remain strongly supportive of mission-led science in solar-system exploration, so SSAP have strongly recommended that the high-level discussions between UKSA and STFC continue with a view to supporting a clear joint priority projects call in future, more naturally suited to mission and bi-lateral opportunities.

The priority projects (and PIs) identified by SSAP for 2019/20 are:

  • Solar Atmospheric Modelling Suite (Tony Arber)
  • LARES1: Laboratory Analysis for Research into Extra-terrestrial Samples (Monica Grady)
  • EST: European Solar Telescope (Sarah Matthews)

SSAP requested STFC continue to work with all three projects to expand their community reach and continue to develop the business cases for future (new) funding opportunities. In addition, SSAP have requested that STFC explore ways in which the concept of two projects—“ViCE: Virtual Centres of Excellence Programme / MSEMM Maximising Science Exploitation from Space Science Missions”—can be combined and, with community involvement, generate new funding for science exploitation and maximising scientific return in solar-system sciences. Initially this consultation will occur between SSAP and STFC.

We would like to thank the community again for its strong support, and rapid responses on very short timescales. A further “light touch” review will occur in 2020, with a new call for projects anticipated in 2021. SSAP continue to appreciate the unfamiliar approach a “call for proposals with no funding attached” causes to the community and are continuing to stress to STFC that the community would appreciate clearer guidance and longer timescales in future priority project calls.

Yours sincerely,

Dr Helen Fraser on behalf of SSAP

The Global Network for the Sustainability In Space (GNOSIS)

The Global Network for the Sustainability In Space (GNOSIS) is an STFC Network+ with the goal of helping researchers within the Particle, Nuclear and Astrophysics areas to engage with researchers from other research councils and industry to study the near Earth space environment. For more details, visit the GNOSIS website or see this issue of the GNOSIS newsletter.

Over the next few years we expect a large increase in the number of satellites in Earth orbit. This will lead to unprecedented levels of space traffic much of which will end as debris. The aim of this network is to understand the debris populations and its impact on space traffic management with a view to enabling a safer environment.

The free GNOSIS lunch event will be held on 18 November 2019 at the British Interplanetary Society at Vauxhall, London, with a video link to the Royal Observatory Edinburgh, to facilitate participation from across the UK. Tickets can be obtained here.

GNOSIS will be producing a programme of meetings for both space operations specialists and subject matter novices and will be able to support the development of collaborative ideas through project and part graduate student funding. Details of our first workshop will be announced in the next month.

If you are an academic with no direct experience but have knowledge of areas such as observations, data analysis, simulation or even law, then register your interest on our website. If you are a currently working in the space sector or if you are just interested in the aims and goals of the network please also register your interest and get involved.

SWIMMR: A £19.9M programme of the UKRI Strategic Priorities Fund

Space Weather Instrumentation, Measurement, Modelling and Risk (SWIMMR) is a £19.9M programme of the UK Research and Innovation (UKRI) Strategic Priorities Fund.

MIST would like draw the attention of the research community to the potential opportunities which will become available as a result of this programme, which received final approval from the Department for Business, Energy and Industrial Strategy (BEIS) in August. The programme will run from now until March 2023 and is aimed at improving the UK’s capabilities for space weather monitoring and prediction. UKRI’s Strategic Priorities Fund provides a means for linking research council investment to governmental research priorities, hence the areas being emphasised in the programme reflect space weather threats to critical infrastructure, as reflected in the UK national risk register.

The programme will be delivered jointly by the STFC and NERC, mainly through open grant calls, but including some elements of commissioned work to be delivered through open competitive tenders. The first calls are expected to appear during the coming weeks. More information about the programme is available through the RAL Space website, and is forthcoming from the NERC web site.

To mark the official launch of the programme and provide more details of the planned activities, a kick-off meeting is being held in the Wolfson Library of the Royal Society on Tuesday 26 November 2019, from 10:30. Pre-registration is required for this event and can be done using this link. We hope that many of you will be able to attend.

Inter‐hemispheric survey of polar cap aurora

By Jade Reidy, Department of Physics and Astronomy, University of Southampton, UK.

The formation mechanism of polar cap arcs is still an open question. Since they were first discovered (over a century ago), there have been conflicting reports of polar cap arcs forming on open field lines [e.g., Hardy et al., 1982; Carlson and Cowley, 2005] and on closed field lines [e.g., Frank et al., 1982; Fear et al., 2014]. It is possible that there are more than one type of formation mechanism [e.g., Newell et al., 2009; Reidy et al., 2017].

Reidy et al. [2018] investigates the interhemispheric nature of polar cap arcs using low-altitude ultraviolet imaging, combined with particle data, to determine whether they occur on open or closed field lines. Figure 1 shows an example of an image from SSUSI (Special Sensor Ultra-Violet Spectrographic Imager) (left) with the corresponding SSJ/4 particle spectrograms (right). The SSUSI instruments, on board DMSP (Defence Meteorological Satellite Program) spacecraft, are UV imagers that scan across the polar regions, building up images over 20 minutes. The SSJ/4 particle spectrometer is also on board DMSP spacecraft and provides measurements of the particle precipitation directly above the spacecraft.

In Fig. 1 the SSUSI image has been projected on to a magnetic local time grid with noon at the top and dawn to the right. The black and grey dashed lines on the particle spectrograms and corresponding black and grey vertical lines on the DMSP footprint (black line on the SSUSI image) give an estimated position of the poleward edge of the auroral for the electrons and ions respectively (see Reidy et al. [2018] for details). Multiple sun-aligned arcs can be seen poleward of this edge, hence assumed to be occurring within the polar cap. The arcs seen on the dawnside of the SSUSI image are associated with ion and electron precipitation (indicated by red bars on both the DMSP track and the particle spectrograms), similar arcs were also seen in the opposite hemisphere. These arcs are consistent with formation on closed field lines [Fear et al., 2014; Carter et al., 2017]. The arc seen on the duskside of the polar cap is associated with electron-only precipitation (indicated by yellow bars). This kind of particle signature is consistent with accelerated polar rain and is hence consistent formation on open field lines [Newell et al., 2009; Reidy et al., 2017].

Reidy et al. [2018] investigated 21 events in December 2015 using SSUSI images and corresponding SSJ/4 data. Nine of these events contained arcs consistent with a closed field line mechanism, i.e. arcs associated with ion and electron precipitation present in both hemispheres (similar to the arcs on the dawnside of Fig. 1). Six of these events contained arcs that were associated with electron-only precipitation, consistent with an open field line mechanism (e.g. the duskside of Fig. 1). Examples of events containing arcs that were not, at first sight, consistent with either an open or a closed field line formation mechanism are also explored. This study shows the complex nature of polar cap arcs and highlights the needs for future study as there is still much to understand about their formation mechanism.

Figure 1. An image from the SSUSI instrument on board DMSP spacecraft F17 is shown on the left. The time at the top of the image indicates the time when the spacecraft crossed 70 degrees magnetic latitude as it passed from dawn to dusk (i.e. left to right). The corresponding data from the SSJ/4 particle spectrometer is shown on the right with the electron spectrogram in the top panel and the ion spectrogram at the bottom. Precipitation associated with polar cap arcs is indicated on the DMSP track on the SSUSI image (indicated by a black line) and the particle spectrograms in red for ion and electron signatures and orange for electron-only signatures.
