Space Weather Message Code: WATA50

Serial Number: 57

Issue Time: 2015 Nov 02 1714 UTC

WATCH: Geomagnetic Storm Category G3 Predicted

Highest Storm Level Predicted by Day:

Nov 02: G3 (Strong) Nov 03: G3 (Strong) Nov 04: G2 (Moderate)

THIS SUPERSEDES ANY/ALL PRIOR WATCHES IN EFFECT

Comment: The arrival of the forecasted recurrent coronal hole high-speed stream has been delayed with onset likely late on day one (02 Nov) and through midday on day two (03 Nov). Geomagnetic storming conditions are likely to persist into day three (04 Nov).

Potential Impacts: Area of impact primarily poleward of 50 degrees Geomagnetic Latitude.

Induced Currents - Power system voltage irregularities possible, false alarms may be triggered on some protection devices.

Spacecraft - Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur.

Navigation - Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur.

Radio - HF (high frequency) radio may be intermittent.

Aurora - Aurora may be seen as low as Pennsylvania to Iowa to Oregon.
