Will the US develop a new satellite for early-warning of severe geomagnetic storms?

The attention of policymakers and business leaders is being drawn towards space weather, the body of environmental dynamics of the solar wind, magnetosphere and thermosphere, and the risks it poses to global infrastructure. The NOAA tracks space weather, and has a set of space weather scales for solar radiation storms and geomagnetic storms. The highest ratings, S5 and G5, can disable satellites, affect power grids, and cause other mayhem.

This scale would appear to cover too little dynamic range, however, as much stronger storms than S5 and G5 are a matter of historical record (see for example the Carrington Event of 1859), and extrapolating the frequencies provided by the NOAA suggests a high probability of trans-G5 geomagnetic storms in the coming two decades, and a ~1-10\% probabilitiy of a Carrington-like event with an order of magnitude higher energy. Given modern infrastructure, such an event could lead to widespread and long-term blackouts, and cause trillions in damage.

In October 2015, the White House published a space weather plan outlining the challenges, and enumerating a number of action items to increase monitoring, understanding, and mitigation of space weather.

A key issue is monitoring: early warning of a solar storm can allow significantly mitigation of its effects. While there are already numerous observation sites on Earth and a handful of satellites (SOHO, STEREO, the Van Allen probes, ACE, and most recently DSCOVR) monitoring space weather phenomena, there is a huge volume of measurement left untouched. Most of the aforementioned spacecraft observe solar wind and the Sun's surface, while the Van Allen probes watch for radiation and magnetic storms; DSCOVR is the only satellite to provide early detection of coronal mass ejections.

Plans to find a long-term replacement for DSCOVR at the L1 Lagrange point do exist as part of the National Space Weather Program's mission over the next decade. Beyond just finding replacements, the recommendations of policymakers (like this whisper coming out of this year's AAAS meeting) push for more observation spacecraft which can collect forecast data in assessment of risks from space weather. The space weather plan contains the action item (5.3.2) to be completed by October 2016:

NASA and DOC will assess space-weather-observation platforms with deep-space orbital positions (including candidate propulsion technology), which allow for additional warning time of incoming space-weather events.

By June 2017, will a US or NASA budget appropriation exist (making reference to the October 2015 report) for the (perhaps initial) design and/or development of a spacecraft whose chief mission is to provide early warning of space weather events?

Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available. With tachyons you'll even be able to go back in time and backdate your prediction to maximize your points.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
