Aurora Corona

When the northern lights are really strong, you might be lucky enough to see them at their zenith, overhead like a corona. The picture shows the beginning of a corona last week.

An aurora corona is a spectacular form of aurora that occurs when you are directly under the magnetic field lines.

It looks as if all the light rays are radiating from a single point high in the sky (the zenith).

Why? It's a perspective effect, just like when parallel train tracks appear to meet on the horizon. In reality, the aurora rays are parallel and follow the Earth's magnetic field, but from the ground they appear to form a "crown" (corona in Latin).

Cabin Aurora

A week's stay in the family's mountain cabin where the starry sky is very dark. One night the northern lights played fantastically beautifully and went high up in the sky above the cabin. The Big Dipper is seen in the middle of the picture, upside down. It almost forms a corona of the northern lights just above. Earlier in the evening I was able to witness a corona right in the zenith, pictures will come later.

 

Amazing Aurora in Stockholm City

Standing in the middle of Stockholm City and capture nice Aurora Borealis is not every night. Heavy lightpollution destroyed much of the show but it was a nice display. Later efter midnight when I arrived home in Vallentuna I enjoyed one of the finest displays I´ve seen so far south, the corona photo show my backyard - amazing!

Moon and planet Mars

Last night planet Mars and Moon were beside each other, photo shows the celestial pair in mist with some corona around the moon. Canon 6D and 85mm lens. And check out a new photo at Carpe Noctem observatory of Jupiter and Galilean moons Jupiter with moons

Planet Jupiter with corona

on parade.

Tonights Harvest Moon

According to folklore this month moon is called the Harvest Moon.
These photos shows the moon through thin clouds that can creat either Halo och Corona, either way it is sometimes very beautiful and can make some spectacular sights,

Månen och planeten Jupiter - Moon and Jupiter

Just nu kan man se planeten Jupiter strax nedanför månen. Om man tittar noga på bilden så kan man även se fyra av Jupiters ljusstarkaste månar. Koronan runt månen och Jupiter bildas när tunna moln passerar framför.

Moon and planet Jupiter together right now in the sky.

If you look closely at the photo you can se the Galilean moons.

Korona runt månen - Lunar Corona

Igår kväll skapades det en korona runt månen när tunna moln passerade, rätt vackert faktiskt om man tar sig tid att titta en stund.
Last night thin clouds passed infront of the moon creating a corona around it, a very nice sight.
