Partial lunar eclipse

7.8.2017 at 21.34 - 22.05 - Espoo (III)
Mika Yrjölä, Ursa (Etelä-Suomi)

To counteract the traumas of the first day after work, I went to try my luck with a partial lunar eclipse. I sifted through the rising direction of the moon and the best possible views of the Espoo seashores in relation to it, and chose the promontory on Westend beach from among a few candidates. I was a little worried about the clouds waving on the horizon, but the Moon still appeared despite them and I set the camera to click the pictures about every three minutes while I myself admired the views. As the moon flew out of the camera’s field of view, I bit the setup and headed home, but I took...

Sumukaari

28.4.2017 at 16.26 - Espoo (III)
Mika Yrjölä, Ursa (Etelä-Suomi)

I was about to work and was about to hop on a bus in Westend when I noticed that fog was still hovering low above the sea. When the schedule wasn’t so critical for over a minute, I took a small excursion to the ocean in case there was material available for halo-april, or otherwise just descriptive views. In both respects you warped; opposite the sun was an obvious fog arc and a few otherwise just a nice landscape flickered.

Binocular comet Tuttle-Giacobini-Kresak

5.4.2017 at 00.06 - Espoo (III)
Mika Yrjölä, Ursa (Etelä-Suomi)

I went a week to try my luck filming the 41P / Tuttle-Giacobini-Kresak comet, although the moon and windy weather that had already reached the first quarter raised some doubts. The comet was found with very little effort in the field of view of the camera and at the same time I finally noticed it visually with binoculars. The stars noticeably flickered on the camera screen while preparing to take the picture, but I still let the body shake for twenty minutes of exposure. Standing between the shooting equipment and the wind, I tried to alleviate its effect even a little, but as you can see from...

Binocular comet Tuttle-Giacobini-Kresak

23.3.2017 at 00.33 - Espoo (III)
Mika Yrjölä, Ursa (Etelä-Suomi)

I had noticed much earlier that this comet would be heatily close to the M108 and M97 on Wednesday, so I watched the weather forecasts all day with enthusiasm and to my delight the weather didn’t disappoint at all, so it didn’t help when I went to try my luck with verme. This was also the first decent opportunity to test the functionality of the pole orientation with the PoleMaster I bought about a week ago, so there was enough interest in that as well. The comet's location near the zenith was followed by a kneeling while adjusting the focus, but eventually everything was ready and the cam...

CTA 102

3.12.2016 at 20.35 - Espoo (II)
Mika Yrjölä, Ursa (Etelä-Suomi)

After the autumn and early winter have been quite dilute in terms of star hobby for my part, I decided to stand up and try my luck with the briskly brightened CTA-102. Despite a bit of bustling weather and a long break, the set-up of the shooting equipment went like a dance once, and the targeting of the subject's rough location to the field of view went surprisingly smoothly. From the individual exposures, I imagined the object was already glistening and after the stacking, the doubts disappeared. A warm mulled wine came in handy after the session.

One halo form

3.11.2016 at 09.14 - Helsinki (I)
Mika Yrjölä, Ursa (Etelä-Suomi)

By work in the morning, I admired the bright sun instead of the almost constant cloud cover of recent times, and after jumping off the bus, I still got a glimpse of the sky. For extra tightening, I noticed a clip of the zenith environment and dug up the camera before proceeding to the edge of the pictorial lathe.

Bright night shining clouds

8.8.2016 at 00.24 - 00.59 - Espoo (IV)
Mika Yrjölä, Ursa (Etelä-Suomi)

A glance at Ireland revealed comments that the night clouds were in a thunderstorm. While not even the first picture of these had been collected this summer and the next day was the first day of summer vacation, there were few excuses to grab the camera and tripod in the stump. After arriving at the seaside in the northern sky, night clouds were seen rather modestly at first, but I still took a few pictures and decided to climb a little higher cliff (marked as an observation site) to see if there was anything to see behind the rock and trees. And after all, there was a small but elegant set of...

Several halo forms

20.7.2016 at 19.33 - Helsinki (II)
Mika Yrjölä, Ursa (Etelä-Suomi)

As I left the guy, I came to glance at the Irishman and notice fresh comments about halo phenomena, so I glanced at the sky myself. The zenith of the surrounding arc immediately caught my eye and I took a few pictures before striving for a slightly more open environment to see if there was more to offer. After getting a little distance to the houses, the side suns and the 22-degree tire were comfortably on the dungeon, so I took a couple more shots while waiting for the bus. This was not an infinitely spectacular spectacle, but a basic one nonetheless.

Siitepölykehä

27.5.2016 at 21.59 - Espoo (IV)
Mika Yrjölä, Ursa (Etelä-Suomi)

I walked by the sea for a couple of hours trying out a 100-400mm lens I bought a few days earlier for everything between bucks and plant silhouettes. Finally, I was left on the cliffs waiting for the sunset in the hope that it would look spectacular and, as can be seen from the pictures, there was no room for disappointment in that respect (nor in the quality of the fresh optics :).

Several halo forms

24.5.2016 at 09.10 - Espoo (II)
Mika Yrjölä, Ursa (Etelä-Suomi)

On a business trip, I paid attention in the sky first to the side suns and then to a stretch of horizon ring, so I paused for a moment to take a few pictures before continuing the trip. On closer inspection, a 22-degree ring was also visible. As a curiosity, I also tried taking a picture through a near-infrared filter to see what the halos with it look like, but unfortunately this did not result in any great aha experience.

Transit of mercury

9.5.2016 at 14.16 - Espoo (II)
Mika Yrjölä, Ursa (Etelä-Suomi)

I had systematically missed all the Mercury overpayments so far, so I marked this time on the calendar several months in advance. Expectations were high on the morning of a critical day when the weather seemed the most promising, so I took all the shooting verses to work except the camera tripod. There was suitably a meeting on the calendar an hour before the h-moment and I already had time to worry as the clock went on but usually the quick myth seemed to be protracted this time. Eventually, however, I survived out of the office in a nearby parking lot about five minutes before the overpass b...

Half-sky auroras

7.10.2015 at 22.54 - 23.42 - Espoo (IV)
Mika Yrjölä, Ursa (Etelä-Suomi)

Throughout the afternoon and early evening, I had hopefully followed speculation on irc and social media about promising space weather. When I finally managed to break away with the camera and the peripherals towards the seashore, the activity had already subsided considerably and even the clouds ran in the sky a lot. However, the stubborn wait was rewarded after twenty minutes as the dilute warping reached a new rather spectacular fireworks display around the sky at its best and both its own head and camera spun around. This time, the observation session also gained an aural dimension when a ...

Arcus cloud

30.6.2015 at 19.22 - Helsinki (IV)
Mika Yrjölä

I had noticed a darkening northern sky a little earlier when I walked in the park, but I was surprised to see a rapidly forming and spectacular cloud formation. I was annoyed when the 14mm ultra-wide was at home this time, but I still snapped a couple of pictures with the widest optics found in the camera bag at the time. The filming was interrupted at the point when a loud crackling began to be heard from the north, and after a few tens of seconds the water then came at least enough to encourage the camera to be moved to the bag and the photographer to run under the nearest canopy.

Half-sky auroras

18.3.2015 at 00.25 - 01.29 - Espoo (IV)
Mika Yrjölä, Ursa (Etelä-Suomi)

In the early evening, while in Kerava, I was annoyed when there were northern lights through the street lights and I was afraid I would miss the whole play in better conditions. Later, when I got home, I still checked the situation in the midnight countries from the balcony and when I saw life in the sky, I decided to take the filming shots with me and head for the seashore. The next hour was then taken in turn, admiring the screen visually and filming. Five from the fatigue of the next working day, yes such a rare treat should be enjoyed when it is available!

Rare halos

17.4.2014 at 08.28 - Helsinki (IV)
Mika Yrjölä, Ursa (Etelä-Suomi)

As I walked from the bus on the way to work, I saw a surprisingly handsome and colorful arc of the zenith environment in the sky and the gaze moving around the sky, it was obvious that there was a more moderately handsome halo show going anyway. So as a compromise between going to a waiting phone conference between rushing and shooting to march to work, I stopped twice to take a set of pictures in case I finally got to try HaloStack using them. The first shot is from the former Nokia / current Jolla and Supercell, the latter near the beginning of the Baltic Sea Street.

Supernova SN 2014J

31.1.2014 at 00.05 - 01.09 - Espoo (III)
Mika Yrjölä, Ursa (Etelä-Suomi)

I had tried a couple of times earlier that week to get a fresh supernova SN 2014J photographed, but the first attempt failed to emerge in the clouds and the second time the camera had, for one reason or another, turned aside and the subject only appeared in a single 15s test exposure; better than nothing but frustrating. Even with the thumb of the second hand, there had been a slight frostbite when adjusting with the equipment, so the balance was pretty bad by then. On Thursday night, the weather seemed moderate, so I decided to try for a third time even though I started to have sleep debt. I ...

Binocular comet Lovejoy

30.11.2013 at 03.22 - 03.12 - Espoo (III)
Mika Yrjölä, Ursa (Etelä-Suomi)

I finally got to record the Lovejoy observation a week ago. A little wise from the previous attempt, I put the phone to wake me up in the morning, when the comet might be a little better out of the light pollution. Without aids, the comet was not visible this time either, but with the binoculars the hazy coma was easily noticeable. Also, through the camera’s optical viewfinder, the subject was barely visible, apparently thanks to the bright lens. The tail remained invisible. I put the camera to shake the shots (this time the hand warmer seemed to keep the lens successfully frosted even though ...

Binocular comet Lovejoy

26.11.2013 at 01.37 - 01.40 - Espoo (III)
Mika Yrjölä, Ursa (Etelä-Suomi)

I finally got to record the Lovejoy observation a couple of nights ago and deal with the exposures that come with it, so here’s a little late coming observation. As the camera shook the exposures from Seoul, I killed time while admiring the rest of the sky, searching for Lovejoy with binoculars. The visual observation was a bit dilute because the comet clawed deep in the light pollution of Espoonlahti / Kivenlahti and it was useless to dream of the tail, but the coma still appeared obviously non-stellar. Later, as the optics began to mist up, I pointed the camera for a moment at the whim of Se...

At least 10 lightning strikes seen

9.8.2013 at 01.00 - 01.58 - Espoo (IV)
Mika Yrjölä, Ursa (Etelä-Suomi)

I had heard a few rumbles a little earlier, but around one I started to see occasional glimpses from the crack of the curtains, so I went to the balcony first to visually observe the thunder Ilja a little later . Shortly before two, the activity began to subside, so considering the state of alertness of the next working day, I could finally go to sleep. I had wondered about the flash that left the discharge channel in some places clearly slower dull areas around its surroundings, the next day it turned out that I had spotted a pearl ribbon flash for the first time in my life. On the reverse of...

Clearly visible night shining clouds

27.7.2013 at 03.05 - 03.20 - Espoo (III)
Mika Yrjölä, Ursa (Etelä-Suomi)

On my way from Ropecon towards home, I noticed night clouds illuminating my joy in the sky, and I liked to take a couple of pictures in addition to visual admiration while marching to a friend's car. I have to admit that I missed an offer to hunt for a better place to shoot by car because the approaching dawn was clearly starting to eat the best blade (I wish I had glanced at the sky an hour or two earlier ...). Not a very spectacular spectacle per se, but the night cloud bonga season finally came to an end for its part this year.
