Aurora of 31 August

We saw a soft white glow from the window and a photo confirmed that there was an aurora outside.
The spectacle is outstanding: two auroras cross the sky making a big X.
Just for few minutes the intensity became stronger and visible to the naked eye. A big gift for Elvio’s Birthday (september 1)

I have enhanced the photos (luminosity +70, contrast +60) to show the aurora but the color rendering depends on your monitor

Every night the window of my room opens my eyesight over an awesome universe of stars.

Outside the window the environment is hostile. The temperature stays between -55°C and -75°C and the average pressure is around 644.4 hPA. Is a double window and between the two windows the temperature stays between -22°C and -41°C. The border of external window is covered by a thick layer of ice. The day (or when i lit the light) the internal window glass show a spectacle of ice cristals.
