The moon almost full, almost clear sky and stars visible in the moonlight and a growing thundercloud – all mixed in with a soundscape so loud and varied that I have decided to purchase a proper recording device so I can share it in the future. The moonlit nights are special in many ways, but [...]

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
Despite a very cold winter, there has been no nacreous clouds this winter. This is the only display that’s coming close. Alas, it’s not nacreous. The sun is down, they shine brightly, they are stationary, but are simply a bleak indication of true nacreous clouds. Last time was in 2008 and the extent and variety [...]
The view from the camp site, or “hotel”, atop Roraima was awesome. I was well protected from the elements in the cave, and could watch nature in all it’s ways and never get wet or cold. The “entertainment” was spectacular this evening. Several cumulunimbus clouds produced lightning for what seemed forever. The altitude made the [...]
This was the end of the first day of a week long trek to the top of Roraima, the highest (2723 m) table mountain (Tepui) in Venezuela, and what a start! The dry season should have started long ago, instead countless thunderstorms supplied plenty of rainshowers and this particular cumulunimbus cloud pushed a layer of [...]
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 [...]
Yet another day of nacreous clouds!
Unknown why, this winter has seen an explosion of nacreous clouds, and this must be the strongest of them all! You never know if the sunset will reveal nacreous clouds, but the wind might indicate a possibility. Oslo lies east of the long north-south mountain range, and when the conditions are right the strong southwestern [...]
I normally never bring my camera to work, but this winter has had such intense displays of nacreous clouds, that I did not take any chance as the western winds were strong today. This is from downtown Oslo (Mølla/Grunerløkka).
