The March equinox

The March equinox is the equinox on the Earth when the subsolar point appears to leave the Southern Hemisphere and cross the celestial equator, heading northward as seen from Earth. Day is as equal long as night, which happens on 20th of the March.

The March equinox  can occur as early as 19 March or as late as 21 March at 0° longitude. 

The March equinox is also known as spring equinox in the Northern Hemisphere and as the autumnal equinox in the Southern Hemisphere.


Weather was not co-operative at all.

Walking in the moonlight


No, this isn't taken on the day. This was actually shot 5:24 am a few days ago. It shows how far current generation of mobile phone's cameras has evolved. I couldn't dream of this few years ago. 


Moonlight consists of mostly sunlight (with little Earthlight) reflected from the parts of the Moon's surface where the Sun's light strikes.


The intensity of moonlight varies greatly depending on the lunar phase, but even the full moon typically provides only about 0.05–0.1 lux illumination.[2] When a full Moon around perigee (a "supermoon") is viewed around upper culmination from the tropics, the illuminance can reach up to 0.32 lux.[2] From Earth, the apparent magnitude of the full Moon is only about 1⁄380,000 that of the Sun.


The Moon's bond albedo is 0.12,[3] meaning only 12% of incident sunlight is reflected from the lunar surface. Moonlight takes approximately 1.26 seconds to reach Earth's surface. Scattered in Earth's atmosphere, moonlight generally increases the brightness of the night sky, reducing contrast between dimmer stars and the background. For this reason, many astronomers usually avoid observing sessions around a full moon.

Sunset is always magnificent

At least when there aren't too much clouds to cover it completely. 




The time of sunset is defined in astronomy as the moment when the upper limb of the Sun disappears below the horizon. Near the horizon, atmospheric refraction causes sunlight rays to be distorted to such an extent that geometrically the solar disk is already about one diameter below the horizon when a sunset is observed.

Sunset is distinct from twilight, which is divided into three stages. The first one is civil twilight, which begins once the Sun has disappeared below the horizon, and continues until it descends to 6 degrees below the horizon. The second phase is nautical twilight, between 6 and 12 degrees below the horizon. The third phase is astronomical twilight, which is the period when the Sun is between 12 and 18 degrees below the horizon. Dusk is at the very end of astronomical twilight, and is the darkest moment of twilight just before night. Finally, night occurs when the Sun reaches 18 degrees below the horizon and no longer illuminates the sky.

Few pictures with iPhone 13 from the Köyliö.



Sun was just about to settle in when I was walking my dog and there were a bit mist in the air too.  


This was taken very late in the evening, but as the iPhone 13 has great camera and snow in the ground reflects the light, it luminated these threes so surreal for the night time.


Same three trees in the morning, just before sun rises above the horizon, but different angle too.


This is the same birch alley that I posted in my Roadscape.photography blog.

Driving in Twilight



Today was my "first" drive from my new house to work. As I left from home the sun was about to rise above horizon. The stage of sunrise known as false sunrise actually occurs before the Sun truly reaches the horizon because Earth's atmosphere refracts the Sun's image. At the horizon, the average amount of refraction is 34 arcminutes, though this amount varies based on atmospheric conditions.


Also, unlike most other solar measurements, sunrise occurs when the Sun's upper limb, rather than its center, appears to cross the horizon. The apparent radius of the Sun at the horizon is 16 arcminutes.





These two angles combine to define sunrise to occur when the Sun's center is 50 arcminutes below the horizon, or 90.83° from the zenith.

New domain attached

I had a plans for this blog for a long time and I wanted to have a unique domain for this and as my other blog, Roadscape.photography, I wanted to this have the same kind of branding, -scape brand. 




Sadly cloudscape.photography was taken by shady LLC, that just parked that domain. So no worth trying to see what's on that website. 

As I wondered what would be okay with this, Godaddy suggested cloudscapes.photography and even thought it had that plural in the scape, it does fit with this blog quite well, since this is mostly about clouds, in plural. One can argue that I could have used cloudsscape.photography, but that double s in the middle of the name isn't good. 



What about my title? Sky is my canvas. 

Well, .com was taken too.

Oh, shit. skyismycanvas.photography is free!

Well, not any more.


This photo kind of puts two things together. Roadscape and Cloudscapes.

Sun pillars

Sun pillars are beams of light that extend upward from the sun. Pillar itself is atmospheric optical phenomenon which is created by the reflection of light from tiny ice crystals that are suspeneded in the atmosphere or that comprise high-altitude clouds.



This was taken in mid February 2022, in Loimaa.







I got there just at the right time! Sun pilar had just aligned with the road and I got out of my car and took this.
