Growing Awareness
Increasing ActivitySolar Cycle 24 maximum approaching – peak in May 2013
1859 Storm 1921 Storm
• The largest geomagnetic storms on record occurred during smaller than average cycles
May 1921 Geomagnetic Storm
13◦
Locations for which aurora were reported on 14–15 May 1921 – Silverman, et al.
Apia, Samoa, 13 degrees south
Potential impact of a 1859 or 1921 geomagnetic storm
Coordinating on ways forward to develop and implement mitigation strategies to safeguard critical infrastructure from the impacts of severe space weather.
High-level government response…
• The Shield Act (H.R. 668) (Feb 2011)To amend the Federal Power Act to protect the electric infrastructure geomagnetic storm (and EMP)
• Meeting at White House with National Security Staff and OSTP (18 Feb)
• Op Ed in NY Times on space weather by Holdren and Beddington (10 Mar)
• Electric Infrastructure Security Summit (EISS) in Capitol building (11 Apr)
NOAA’s commitment to improved operations
• Model transition- ENLIL model in operations by 2012- Working with CCMC on geospace
model
• Upgrade operational product suite
• Continue and expand coverage of critical observations
