    They are common in Edmonton, Alberta Canada, 53.5 degree North. Mostly 
    seen from start of June to possibly end of July. Not as prominent this 
    year as previously seen but the season is not over. General times and 
    directions are correct in your statement.
    
    Our other well known sky event is Aurora. So common around here that we 
    consider it as a nuisance.
