WATCH ON YOUTUBE

Mariusz Krukar

My channel is aimed at:
- Astronomy (rare atmospheric phenomenas, celestial events, timelapses),
- GIS & geography (simulation and modelling environmental processes),
- Education (explanation how to use or how to do sth),
- Test equipment (smartphones, GoPro's drones, DSLR cameras with lenses),
- Travel (occasional footages),
- Weather phenomenas (footages, timelapses).

Hope you will enjoy!

The compilation of time-lapse from 2 working webcams located in Ushuaia at Tierra del Fuego - the southernmost tip of Argentina, where the shortest day can be observed on the winter solstice on June 21st. A random timespan for the screenshots has been applied. The full period covers around 10 hours between the nautical dawn to nautical dusk. Both the beginning and end of the video mark the moment of visual complete darkness gained under the high level of artificial light.

The full HD animation of the lunar shadow moved across North America. Each town is visible on the eclipse path, which should be really beneficial for planning observations in certain areas. This is the most detailed vizualisation to be found on the web.

Total solar eclipse 2024 North America - high detal

The 3rd part of the complex animation shows the path of the April 8, 2024, total solar eclipse known as the 2024 Great American Eclipse. It includes 4 major views: the top with Google Hybrid overlay (325-330 km altitude), the shadow in & out (50km altitude), and local views (10-25km).
The animation covers: Arkansas, Missouri, Tennessee, Kentucky, Illinois, and Indiana and the complex view of Indianapolis.
This GIS-based video has been made with the eclipse data based both on NASA.gsfc.eclipse service and Xavier Jubier eclipse page, from where I picked up the most important calculations. I also used the Eclipse24.org webpage in order to grab the local area boundaries.

The simulation of the lunar Metonic cycle between May 19, 2022, and May 19, 2041 displays the southernmost moonsets from Jodłówka Tuchowska Lookout tower, which stands just next to the Brzanka hill. The view is of the Tatra Mountains at a distance of about 100km. We can get to know about the following occurrences across this 19 years period:
- octaeteris
- major lunar standstill
- minor lunar standstill

The clever and quick method of preparing any speed limit map in QGIS, including:
- downloading open-source data and loading it to QGIS
- the ordering of the layers
- vector research tools (selection within the region)
- intersection tool
- categorized symbology and its customization
- preparing the map in the print layout
