An asteroid passed on front of a star on Oct. 19
21.10. On Tuesday at 01:50 Petri Kuossari photographed an occultation by asteroid 980 Anacostia in Tervakoski, Janakkala. The about 70 kilometers wide asteroid was at 1.308 AU from us at the time of the event and passed on front of a 10,5 magnitude star. The video Kuossari made shows the occultation beautifully combined with a light curve. Kuossari sent the observation to SETI Institute and expects more detailed data on the occultation in a month's time
Lunar halos preceeded the rain
20.10. Last night a wide warm front with its rains approached Finland from west and the high cloud sheet which advanced it showed halos all the way from Lappeenranta to Salla. Here is a stack of the display taken by Petri Martikainen in Juva at 21.06-21.16. In the upper left corner of the picture is short-lived 120° parhelion, which Martikainen also noticed visually. If the 120° parhelion has been cut off from the news image, see Martikainen's observation .
Supernova remnant Abell 85
20.10. Erik Pirtala got ready the less frequently photographed object Abell 85, which is a supernova remnant in the constellation of Cassiopeia. "The project, which started right in the very first days of the month, came to an end last night when even Eastern Finland got a glimpse of clears skies," says Pirtala. The total exposure was 17 hours. Abell 85, also known as CTB1, is located 9,800 light-years away from us and its size in the sky is that of a full moon.
Lucy probe in Hankasalmi Observatory image
18.10. Nasa launced on Saturday, Oct. 16, Lucy mission on its long journey to explore Jupiter Trojan asteroids. Arto Oksanen captured the probe next day with the Hankasalmi Observatory's 40 cm telescope. Lucy was 600,000 km from us at the time of the photo. The spacecraft will initially remain close to Earth's orbit and will pick up momentum from three near-Earth bypasses during its flight.

22 degree perimeter to hear and I do not know I just imagine, but is also the inner perimeter? I'll leave it to the Savior to decide if. Photo taken at 11:32 p.m.

On Monday night, I photographed the Asteroid 980 Anacostia overpass to the Seti Institute, would look like positive observations. This finding led to more detailed research at the Seti Institute as a researcher by Joe Asencio. In a month, I will probably get more accurate data on the overrun.

A nice haloshow in the light of the moon struck strangely after a long relentless season. I put the camera to capture the stack as soon as I got home from things. Zykki and 120 ° saur also shone brightly in the sky for a while, but the latter in particular faded away really quickly. Fortunately, it had barely fit in the camera's field of view. After that, I went to another camera to take pictures of the whole sky, but the best moment had already passed. Even the northern lights seemed to stick to the full sky. The main image is a gif animation from 9:32 pm to 10:02 pm, images of unprocesse...

Lokakuu on ollut varsin surkea havaintokelien osalta. Kuun ihan ensimmäisinä päivinä aloitettu projekti tuli maaliin viime yönä, kun Itä-Suomeenkiin saatiin parin tunnin kirkas pätkä. Kuvasin tämän kohteen 17,2 -tuntisena projektina . Sumu on kapeakaistassa HOO -paletissa, ja tähän on löyty RGB -tähdet päälle. Todella himmeä ja haastava kohde. Tässä meni aikansa että löysi edes sinne päin toimivan määrän ja maskauksen kohinanpoistolle. Herkästi näissä himmeissä siloittelee liikaa ja tekee lopputuloksesta liian muovisen.

I bongas on a very short-lived (about a second, about roughly) yet very bright satellite reflection repo shooting trip. Based on the Heavensat study, the most likely candidate to cause reflection is Iridium 29 ( #24944).

When I reached Suhru Ruuhijärvi, I was practically in the state of mind that I could tread straight back home. Lots of bustle in the sky and a bright full moon. The lake was also partially frozen and no reflection images would be obtained. It was really cold there too, my outside gauge looked -12 and on the lake that always feels worse. Even your fingers are always frozen when you adjust the camera. As for the northern lights, they pretty much covered the whole sky at several moments, the brightness just moderately, sometimes with a nice movement. The moon also had a great halo. Worth monitori...

The northern lights and the halo of the moon were able to delight comfortably in the early evening. As the moon moved higher, the northern lights also ceased. The pictures were taken from the shore of the lake and used a big 100. The northern lights were bright at this point and the green color was seen racing with the halo of the moon.

On the sauna ice for a moment, the wondered "is that" line in the sky "dim Northern Lights" changed to "get the camera, don't steam the lens, remove the lens cap" : D I mostly leave the identification of halos to the wiser!

Clear skies for a long time and a magnificent arc of northern lights with the moon. Frost tightens to record levels.
