This just in from NOAA:
Space Weather Message Code: WARK06
Serial Number: 160
Issue Time: 2009 Aug 30 1641 UTC
WARNING: Geomagnetic K-Index of 6 expected
Valid From: 2009 Aug 30 1641 UTC
Valid To: 2009 Aug 30 2100 UTC
Warning Condition: Onset
NOAA Scale: G2 - Moderate
NOAA Space Weather Scale descriptions can be found at www.swpc.noaa.gov/NOAAscales.
During a G2 Magnetic Storm one can expect the following:
Power systems: high-latitude power systems may experience voltage alarms, long-duration storms may cause transformer damage.
Spacecraft operations: corrective actions to orientation may be required by ground control; possible changes in drag affect orbit predictions.
Other systems: HF radio propagation can fade at higher latitudes, and aurora has been seen as low as New York and Idaho (typically 55° geomagnetic lat.).

G2 (moderate) geomagnetic storms were observed on 29 August due to high speed winds from a coronal hole on the Sun. -- source
