Why you should communicate space weather
  • Its cool and fascinating gets people excited
    about space science
  • Its a natural hazard so its important for the
    public to know about it
  • A variety of audiences are interested in space
    weather (school kids, engineers, policymakers),
    so easier to communicate than other topics
  • You are less likely to get it wrong than
    journalists/sci communicators
  • Communicating science to wider audiences is
    great to hone your communication skills (improves
    your scientific writing too)
  • Could lead to interdisciplinary collaborations
    increase in citations
  • Justify the taxpayers money that funds your
    research attract more public support for your
    science
  • Inform policy make sure legislation relating to
    space weather (including funding decisions) is
    based on sound science

Space weather
Changes in the near-Earth space environment,
which are caused by varying conditions on the Sun
and its atmosphere.

The Sun
  • Has a diameter of 1,391,000 km 109 times the
    Earths diameter
  • Its some 150 million km, or 8 light minutes,
    away
  • Glowing sphere of hot (ionised or electrified)
    gas called plasma
  • Rotation (at the surface, the rotation is faster
    at the equator than at the poles) and convection
  • It has a magnetic field (its a big magnet), but
    a very complex one

    Earths diameter
  • Its some 150 million km, or 8 light minutes,
    away
  • Glowing sphere of hot (ionised or electrified)
    gas called plasma
  • It rotates differentially at the surface, the
    rotation is faster at the equator than at the
    poles
  • It has a magnetic field (its a big magnet), but
    a very complex one
  • It has an 11-year sunspot cycle or solar cycle
    max and minimum

  • Glowing sphere of hot (ionised or electrified)
    gas called plasma
  • It rotates differentially at the surface, the
    rotation is faster at the equator than at the
    poles
  • Like the Earth, it has a magnetic field (its a
    big magnet), but a very complex one
  • It has an 11-year sunspot cycle or solar cycle
    max and minimum
  • It produces a stream of electric particles, the
    solar wind, that flows out of its upper
    atmosphere reaches the Earth (and its protective
    magnetic shield) and beyond!

Solar wind and aurora
  • Auroras are one of the most visible effect of
    space weather

16
Solar wind and aurora
  • Auroras are one of the most visible effect of
    space weather
  • Occur when the energetic particles carried by
    the solar wind break through the magnetic field
    protection and travel along the magnetic field
    lines entering the Earths atmosphere close to
    the poles
  • Particles hit the atoms that make up the Earths
    atmosphere and energise them, causing them to
    release photons (light particles)
  • Auroras are usually weak and only visible at
    high latitudes
  • But sometimes the solar wind carries a lot more
    radiation, energetic particles, and even plasma,
    from the Sun

17
Solar storms and geomagnetic storms
  • Solar flares rapid outburst of radiation and
    energetic particles (can release 10 million times
    more energy than an exploding volcano)
  • Coronal mass ejection (CME) a larger scale,
    violent ejection of material into space up to a
    100 billion kg of plasma
  • Can happen more frequently at the peak of the
    solar cycle (more sunspots)
  • Solar wind carries the material onto Earth, if
    solar storms are directed towards it can impact
    satellites
  • Strong solar storms can cause geomagnetic
    storms disturbances of the Earth magnetic field
    can impact technological systems on Earth (and
    we get to see stronger lower-latitude auroras!)
  • On average, these events disrupt human activity
    1-2 times per solar cycle

19
Effects of space weather
  • Damage to satellites (inc. communications)
  • Radiation hazard (astronauts, but potentially
    also for air crews/passengers)
  • Distortion of radio signals
  • Navigation errors (GPS)
  • Power blackouts (e.g. Quebec blackout 1989,
    Sweden power outage 2003)
  • Aurora (not all doom and gloom!)

20
Monitoring and protection
  • Effects are more damaging now than in the past
    because we rely more on technology. But our
    weakness is also our strength we have
    spacecraft watching the Sun 24/7
  • Spacecraft can provide CMEs warning 1-3 days in
    advance (but geomagnetic storm warning may only
    be available 1hour in advance)
  • Astronauts at the Space Station can seek shelter
    from radiation
  • Airplanes can be rerouted
  • Most satellites have some protection against
    radiation energetic particles

21
Take-home messages
  • Space weather is a natural phenomena that can be
    beautiful and, sometimes, can affect our
    technology
  • Theres protection from it, but we need to keep
    watching the Sun!
  • Investing on protecting our technological system
    from space weather and on having better warning
    systems for geomagnetic storms also important
  • Engineers and policymakers need to be well aware
    of space weather as they need to make sure space
    weather is monitored and forecasted properly
  • You dont need to worry about space weather!
  • But you should know about it so you are not
    surprised/scared when (e.g.) GPS not working
    properly or theres a power blackout so that
    you understand the need for funding space weather
    research/monitoring

22
So, how to communicate space weather?
  • Show images short videos/animations
  • Explain jargon (e.g. plasma hot, electrified
    gas)
  • Everyday examples give the reader/listener
    something to relate to (e.g. explain
    distances/sizes using comparisons with familiar
    objects)
  • Make your presentation/text current (e.g. show
    images of the Sun today, last week, last month)
  • Bring people closer to solar space weather
    research (e.g. tell them they just need to use
    Google to find out how active the sun is looking
    today, or what the space weather conditions are)
  • Show them space weather and its effects are
    real! (e.g. geomagnetic storms caused a power
    blackout in Sweden in 2003)
  • Take-away messages highlight what you want
    people to keep in mind

23
General good science communication/writing rules
  • Assume the audience knows nothing about your
    research but dont assume they are stupid and
    wont understand it
  • Short, simple and concise style be
    conversational Dont be effulgent or
    felicitous, be bright and happy instead!
  • Speak/write clearly, avoid acronyms and
    technical terms
  • Writing roughly one idea per sentence and one
    concept per paragraph
  • Writing use the active voice, vary length of
    sentences (some short, some long but not too
    long)
  • Target your message to your audience

24
Target audience policymakers
  • Be brief, be balanced, be objective, be clear
  • Get your facts right, focus on the main messages
  • Language can be a bit more technical (level of
    education higher), though still simple and clear
    to a non-scientist
  • Background (sun, solar storms, etc.) should be
    very brief
  • Focus on the effects impacts so that they
    understand space weather can be a problem
  • Focus on monitoring, forecasting, protection and
    mitigation so that they know what can be done
    about it
  • Focus on funding because government agencies
    decide on funding for some research agencies

25
Target audience policymakers (contd)
  • Example POSTnote on Space Weather
  • POST UKs Parliamentary Office of Science and
    Technology provide analysis of policy issues
    relating to science to help UK parliamentarians
    examine science and technology issues effectively
  • Produce short notes (24 pages), which take
    about 23 months to research and draft and are
    reviewed extensively (industry, academics,
    parliamentary staff, etc.)
  • http//www.parliament.uk/documents/post/postpn361
    -space-weather.pdf (with Chandrika Nath)
  • More information How do I brief policymakers
    on science-related issues? by Chandrika Nath

How can you get involved in space-weather
communication
  • Be pro-active and do more outreach
  • Blog about your work, talk about it on social
    media, give popular science talks, go to schools,
    etc. or contact your press officer if you have
    new and important/exciting results
  • Being involved in policy may be harder be
    patient, persistent, available
  • If your story is in the media, it may indirectly
    influence policymaking since most politicians get
    their sci information from the media
  • Make yourself available to provide information
    for policy briefings, write to your MP or
    parliamentary office of science
  • Apply for a science policy initiative
    (scientist-MP pairing schemes, POST fellowships,
    opportunities at the European Parliament's
    Scientific and Technological Options Assessment,
    etc.)
