Some long lasting auroras sparkled beautifully last night, 9th Sept 2015.
From evening to midnight auroras changed its shape, size, brightness and grew strong and high now and then.

Aurora changes color depending on the existence of any sunlight or moonlight.
Aurora shined red, yellow and purple during twilight with the sun light still effecting the sky.

The blue sky becomes black while aurora is the only source to light the ocean.
