**** GEOMAGNETIC ACTIVITY EXPECTED TONIGHT ****

Strong solar wind flow is being observed at the ACE spacecraft. The unusual flow began at 1625 UTC on 23 May, but has become more intense during the last 2 hours (from 6:00-8:00 pm MDT on 23 May). These signatures indicate that a moderate (G2) or possibly a strong (G3) geomagnetic storm is likely to occur over the next 12 hours.

Geomagnetic storms may affect some electrical power systems, spacecraft operations, and communications systems and are associated with auroral activity. For details see the NOAA space weather scales at http://www.sec.noaa.gov/NOAAscales.

Data used to provide space weather services are contributed by NOAA, USAF, NASA, NSF, USGS, the International Space Environment Services and other observatories, universities, and institutions. More information is available at SEC's Web site http://sec.noaa.gov
