       Viewing is possible from New York to Idaho.
        
       Metro Vancouverites could see an awe-inspiring northern lights display
       early this week.
        
       The National Oceanic and Atmospheric Administration (NOAA)'s Space
       Weather Prediction Center issued a G2 (moderate) geomagnetic storm
       warning for Monday, May 6 "due to the potential arrival of a [coronal
       mass ejection]." (see slide two).
        
       On Monday, the University of Alaska Fairbanks (UAF) shows highly
       active auroral activity with displays visible "overhead from Inuvik,
       Yellowknife, Rankin and Iqaluit to Vancouver, Helena, Minneapolis,
       Milwaukee, Bay City, Toronto, Montpelier, and Charlottetown," and also
       low on the horizon in places as far south as Salem, Indianapolis, and
       Annapolis (see slide three).
        
       The university's online aurora monitor map shows what regions the
       aurora's green glow may be visible overhead and where it may be
       visible low on the horizon. Additionally, there is a brief description
       below the map of the aurora activity on that particular day. You can
       switch to other days to see the forecast, too.
        
       The UAF's aurora viewing map shows the vibrant green glow covering
       well below Vancouver on Monday, meaning there could be opportunities
       to view the aurora overhead rather than only low on the horizon,
       weather permitting.
        
       ### The Metro Vancouver weather forecast and aurora viewing
       opportunities
        
       On Tuesday, the UAF's map shows less of the green glow covering the
       Lower Mainland but opportunities may still exist to see active auroral
       displays low on the horizon.
        
       Displays low on the horizon are expected to be visible from Vancouver,
       Great Falls, Pierre, Madison, Lansing, Ottawa, Portland, and St.
       Johns.
        
       The Metro Vancouver weather forecast looks favourable for at least one
       of the displays. Summer-like weather is expected to emerge later this
       week but skies should clear on Tuesday.
        
       How will you know when there may be some decent breaks in the cloud
       coverage?
        
       Castellan recommends sky-watchers look at Environment Canada's online
       cloud prediction tool for astronomical purposes. It shows when there
       may be clearer times when the aurora is active.
