During the Pi Day, 3-14, (2022 March 13th to 14th) a G2 geomagnetic storm could be seen from Estonia. Cracks in Earth’s magnetic field, more frequent around the equinox due to Russell-McPherron effect, make these storms a magnificent spectacle of northern lights. This video was recorded last night from Viimsi, north of Tallinn, and shows the auroras that could be seen.
The colors of the rainbow are 7 but in front of me I have a white rainbow. You can see that it’s not a halo or other atmospheric optical effect, it’s a rainbow, but it’s white. That idea that seems so simple is difficult for me to assimilate, because they had always explained to me how rainbows are formed and why colors are seen, and there in front of me I had one that did not comply with the rules. […]
Seeing a tornado has been on my mind for a long time, and coincidentally Estonia is a privileged place for it. Located in one of the tornado alleys that exist, it is visited very often by this phenomenon. But although my curiosity is great, my knowledge is small. So in summer, whenever there is a chance of a storm, I go out to look at the clouds, and at the moment what I am finding are funnel clouds that are […]
The April 2019 fire that destroyed part of the Notre-Dame Cathedral was an event that saddened us all. Its famous gargoyles and its spire were unique. Here you can find some pictures of what it was like before the fire and also an extraordinary detailed image of the Spire of Notre-Dame.
It is a memory of the tragedy of the 20th century. A time where the greatest senseless massacres that humanity has experienced were known. Patarei was one of those places where, during that madness, revenge and cruelty were exercised hidden from public view.
The fauna of the Estonian forest is very rich. The large expanses of forest allow to find many different species of animals.

Method of capturing the image of lightning in a storm cloud during the day. During the summer months storms are very common, many of them discharge numerous lightning that are a great spectacle. When the storm clouds approach, it is a sign that we have to prepare if we want to take lightning photographs. The best time to photograph them is at night but sometimes these storms happen during the day, how to photograph them? During the night, it is […]
Here are some images of the Comet C/2020 F3 NEOWISE from Estonia (July 7 to 18 2020). On its way through the Estonian skies the comet crossed over storms and Noctilucent clouds (NLC). On those dates there is no night in Estonia. From mid-May to the end of July, the night in Estonia is replaced by a nautical twilight that barely showing the brightest stars. This made it impossible to appreciate the details of the comet or to be able […]
During the summer season there are many opportunities to see spectacular noctilucent clouds NLC, but in this video I want to show you what it looks like during one single night (the night of 9th July 2020) and the great variety of types and shapes that noctilucent clouds NLC can present at all times. You can also see the common clouds below, moving in a totally different way. Music by Stellardrone (Creative Commons: CC by 3.0) stellardrone.bandcamp.com
The Kolga manor mansion can pass as insignificant in sight of the average tourist. However, this peculiar, unrestored, but well-preserved, empty building is magnetic to many photographers and filmmakers looking for a place with personality and an aesthetic of an aged and missed classicism. Its owners have chained unique and dark stories that make it even more interesting. Kolga’s mansion is one of those types of buildings with heavy doors, intricate stairs, dark corners and a multitude of details that […]
No, it is not Fukushima. Yes, it is a mutation. This is a curious case of fasciation. It is rare, but not unusual for Marguerite daisies. According to Wikipedia: Fasciation, is a relatively rare condition of abnormal growth in vascular plants in which the apical meristem (growing tip), which normally is concentrated around a single point and produces approximately cylindrical tissue, instead becomes elongated perpendicularly to the direction of growth, thus producing flattened, ribbon-like, crested (or “cristate”), or elaborately contorted, […]
