Draconid meteors and Northern lights (Aurora borealis)

Draconid meteors and Northern lights (Aurora borealis)

The Draconid meteors are generally faint, so with a near full moon the amount seen this night were few and far between. Being inside the huge dome of Oslo’s light pollution adds to the overall dimming of the meteors. I saw mostly very faint “blips”, and once in a very long while some bright streaks [...]

Draconid meteors

Draconid meteors

This is a composite of 14 exposures that all contain one or more Draconids, making the dotted star trails. As Oslo and the near full moon strongly pollutes the dark sky, a full long exposure star trail scenario would simply add too many air planes and light too see the faint meteors. Most of the [...]

Northern lights (Aurora borealis)

Northern lights (Aurora borealis)

Finally some intense auroas AND clear skies! It seemed at first to be only a dim band high in the northern sky, but at around 23:15 local time (21:15 UT) a sudden burst in intensity and spread! It covered all of the sky up to and a bit beyond zenith. This time lapse spans more [...]

Roraima rainbow

Roraima rainbow

There are countless waterfalls on and off Roraima, large and small. If the sun is out and the angle is right, a rainbow will flash as in this photo. One can walk to such a place, or sit by one and wait until the sun and angle makes it happen all on it’s own.

The northern lights continued

The northern lights continued

Since the first shots at around 20:40, the clouds moved in and the northern lights slowly withdrew to the north, as if the show was over. 3 hours later while walking my dog I see a fast moving swirl over the tree tops, and quickly walk home to grab the camera. There were no more [...]

At last some northern lights

At last some northern lights

Seeing northern lights in the light pollution of Oslo is one thing, another is weather conditions. This autumn has not been favorable, with long periods of overcast and rain. Finally everything came together for a great veiwing. This time the display was mostly a dim and mellow veil, stretching allmost to zenith. Only few and [...]

Nearly missed the northern lights!

Nearly missed the northern lights!

The forecast suggested a great show this evening. I went out and looked for the northern lights several times without seeing any, and I wasn’t really surprised, as the summer sky still was very bright, and the northern lights had to be very strong to compete. I only got one shot where the northern lights [...]

July Milkyway from the Anaa atoll

July Milkyway from the Anaa atoll

Going to this remote atoll in the south pacific I was in anticipation of a clear sky and no light pollution. The sky was not entirely clear, so I had to wait for the small clouds to pass between shots. The amazing thing is that with no visual aid I could see the shadowbands of [...]

First northern lights (Aurora borealis) of 2010

First northern lights (Aurora borealis) of 2010

According to the Auroral Oval there should be strong auroras – alas! I was glimpsing what could be northern lights, but they were weak, and featureless. Disappointed I was heading to bed, but one final look outside revealed something interesting. I grabbed my camera and tripod, and rand outside. Unfortunately, before I had set it [...]

First northern lights (Auroae borealis) of the season

First northern lights (Auroae borealis) of the season

Even during the time of the deepest solar minimum in a century, it’s possible to see the aurorae. Albeit dim and hardly vislible to the untrained eye. It was a mild, windy and starry night. The grasshoppers playing in the trees. Low in the northern sky I could see a very faint hue of green. [...]
