Explanation:
Will it be curtains for one of these auroras?
A quick inspection indicates that it is curtains for both,
as the designation
"curtains" well categorizes the type of aurora pattern pictured.
Another (informal) type is the
corona.
The
above auroras resulted from outbursts of
ionic particles from the
Sun during the last week of September.
A polarity change in the
solar magnetic field at the
Earth then
triggered auroras over the next few days.
The
above picture was taken on October 3 as
fleeting space radiation pelted the
Earth's atmosphere high above the
Yukon in
Canada.
