Three buckets were spending time in the club on Tuesday night, and the sun could be watched and observed in many different ways; visually with a telescope (Astrosolar film in use!), digiscoping, a planetary camera, and otherwise just admiring the landscape after the sun has already set below the horizon. Initially, more detailed images of sunspot groups (2978 and 2975 & 2976 [of which also separate images]). 5. in the picture ‘digested’ The sun near the horizon at 20:10. Figure 6 The Pillar of the Sun could have had its own separate observation, but let us also add in this context --- Spring i...

NGC 3893

23.3.2022 at 23.35 - Nakkila (III)
Juha Ojanperä, Porin Karhunvartijat

NGC 3893 is a spiral galaxy discovered by William Herschel in 1788 in the constellation of the Big Bear. The galaxy is a so-called "grand design spiral galaxy" with clearly developed and showy spiral arms. Unfortunately, the spiral branches did not stand out with my observation device. Visually, the galaxy appeared as a roundish, hazy spot that is fairly uniform in its brightness distribution. There is a weak central brightness in the middle of the galaxy. The galaxy is slightly elongated, with a long axis that appears to be approximately north-south. Herschel's classification of the objec...

NGC 3877

23.3.2022 at 23.20 - Nakkila (II)
Juha Ojanperä, Porin Karhunvartijat

NGC 3877 is an Sc-type rod spiral galaxy discovered by William Herschel in 1788 in the constellation of the Big Bear and visible to us almost sideways. The galaxy is part of the M109 galaxy cluster. Visually, the galaxy appeared as a dim, thin, and oblong glow. The galaxy has a fairly uniform brightness, with a faint central brightness in the middle. The long axis of the galaxy is approximately southwest-northeast. Herschel's rating for the item was H I-201, i.e., the 201st item in Class I, "clear mists." #Herschel 400

NGC 3726

Juha Ojanperä, Porin Karhunvartijat

NGC 3726 is a spiral galaxy discovered by William Herschel in 1788 in the constellation of the Big Bear. Visually, the galaxy appeared as a large, rather dim and elongated glow. The brightness distribution of the galaxy is fairly even, with a weak central brightness in the middle. The long axis of the galaxy is north-south. At the north end of the galaxy is a foreground star with a magnitude of 12.5. Herschel's classification for the object was H II-730, i.e. Class 7, "dim fogs," the 730th object. #Herschel 400

Half-sky auroras

13.3.2022 at 19.45 - 21.00 - Nakkila (IV)
Juha Ojanperä, Porin Karhunvartijat

As expected, the spectacular northern lights show appeared in the sky early in the evening, only at dusk. At its best, the Northern Lights area extended well toward the southern sky over the zenith. An active, radial belt was visible in the northern sky. To the south of the belt was gauze, which in essence resembled the so-called dune shelf. I photographed the gauze for the dunes, but this time the dunes did not appear.

All-sky aurora

13.3.2022 at 19.30 - 03.30 - Ulvila (V)
Juha Ojanperä, Porin Karhunvartijat

On the night of March 13/14/2022, a G2-class geomagnetic storm was experienced. The storm at times caused a really spectacular northern lights show, which for good reason can already be described as the best of the season so far. The cameras of the bear camera recorded this play as well. Based on the videos from the bear camera, it can be seen that there were 3 storms during the night, 1st from 7.30pm to 8.30pm, 2nd from 10.40pm to 11pm, 3rd from 00.30am to 3.30pm. The last or third of these was also the most spectacular of the night. At this point, the northern lights belt became active and r...

Quiet aurora arc

Juha Ojanperä, Porin Karhunvartijat

Piipahdin ulos tarkistamaan revontulitilanteen yöllä 11./12.3.2022, havaintohetkellä matalalla pohjoistaivaalla näkyi vaatimaton, himmeä revontulikaari, jossa näkyi vähän säteitä ajoittain. Valosaaste ja kirkas, reilu neljänneskuu korkealla taivaalla haittasivat revontulten näkymistä. Kuvien kontrastia parannettu, jotta vaatimattomat revontulet näkyisivät paremmin.

Revontulia oli tallentunut Karhukameraan alkuillasta varhaiseen aamuun yöllä 11./12.3.2022. Ajoittain muuten vaisu näytelmä heräsi aktiiviseksi vyöksi, joka oli ajoittain melko näyttäväkin.

The northern lights of the night on March 5, 2022, photographed from Nakkila. The northern lights of the early evening passed me due to social reasons, but I got to the scene in time just before the start of the third storm of the night. Here are pictures of the third sub-storm. Fortunately, the cameras in the bear camera recorded an all-night Northern Lights play. The third sub-storm I observed showed a pattern typical of a sub-storm (and a northern lights play): initially, a dim, steady arc of northern lights is visible in the northern sky, spreading toward the south. At some point, the arc ...

The zodiac light can also be seen in Nakkila, although it has to compete with several light pollution sources. The first image jpg directly from the camera, the second image slightly contrasted.
