A summer with absolutely no noctilucent clouds in July! The few nights with clear skies passed with little sign of them. The other nights were more or less 100% cloudy. Now the dark nights are coming back, marking the near end of possible sightings. The weather forecast is good for the next few days, so [...]
First night of August and the first noctilucent clouds of the summer – at least the first good ones! There have been some fine veils and wisps in between the clouds, but nothing close to this display. I also made a time-lapse video – see it in this post
Tonight’s Noctilucent cloud show was fast moving, bright and spectacular. Watching it is one thing, but a time-lapse of many hundreds of exposures is a totally different matter. By playing back as a movie you can see how the ripples and waves are moving, as well as how the NLCs are moving in a totally [...]
After more than a week of cloud cover, tonight started with a very bright and widespread display of NLCs. It was far south on the sky and ranged all the way to the northwest/northeast. Only a few times have I seen NLCs go further south than zenith. As the sky was clear I assumed it [...]
Finally a strong display of NLCs! After a heavy thunderstorm the clouds slowly dissipated and revealed NLCs. They were mostly ripples this time – like sand in the shallow seas or the sand dunes of a desert. NLCs are really great on photo, but simply awesome as a time-lapse.
First decent display of the season, but as it’s very close to the solstice the sky is very bright throughout the night and thus the NLCs are not as prominent as could be later in the summer. [quicktime]http://www.ross.no/communicate/wp-content/2009/06/DSC_0762.MOV[/quicktime]
Low-hanging in the northern sky is also a beautiful vista, but nothing compared to those nights where the clouds cover the sky all the way to zenith.
Yet another night with noctilucent clouds, albeit much dimmer than some of the other displays this summer.
Some summers might pass without a single display, while others are filled with night after night with intense shows. When the clouds are as strong as here, the dark of night is turned into a milkywhite twilight, as they brighten the sky as an enormous reflective layer all the way to sunrise. 00:47:58 01:06:35 02:12:26 [...]
