In this article, I would like to describe my a few years of adventures in the Krosno branch of the Polish Society of Amateur Astronomers, where I could develop my noble hobby. Except for my activities, I want to show the best and the most unique observations made by members of this society in the Krosno region. Krosno is a town located in the southeast part of Poland in the Subcarpathian region.
Krosno branch of Polish Society of Amateur Astronomers was established in 1953 by an amateur group led by Jan Winiarski, who was the biggest popularizer and animator of the astronomical observations in Krosno. At that time he used to arrange public stargazing on the market, which gathered tens of people from the city and environs. Except for stargazing a lot of lectures took place at that time.
The Krosno branch of Polish Society of Amateur Astronomers managed many technical and scientific observations throughout its over 50 years’ presence. To show it briefly I listed the most important observation events below in order to timeline:
1954 – Total solar eclipse in Sejny, northeast Poland.
1957 – The last segment of the carrier rocket, that lifted a first artificial satellite into orbit.
1985 – Total lunar eclipse in Krosno. It was a groundbreaking observation for the Krosno branch because the observers had a new Newton 250mm telescope. They captured the first pictures of the eclipsed Moon. On top of that, they reported a 5 9mag stars occultations during the eclipse, that was only one observation in Poland during that eclipse.
1986 – Halley’s Comet, professional observations, which was handed to the Halley’s Comet Museum in Pasadena, CA. Those observations were carried out between November 1985 and May 1986.
1988 – The Venus occultation. It was a very nice 84 seconds lasting phenomenon.
1989 – The 28 Sagittari (Sgr) occultation by Titan. It was a very rare celestial event. The brightness of the 28 Sgr star dropped from + 5,4 mag to 8 mag.
1990 – Total solar eclipse expedition, Bielomorsk in North Russia. It was an Astro tourist journey for 50 people both from Poland and Latvia. Due to the cloudiness during totality it wasn,t successful hover the trip included many places e.g. Riga and the Pulkovo astronomical observatory.
1990 – Shoemaker-Levy Comet observations, which contained 30 separate measurements of brightness and location in the sky. The biggest measured brightness was +4,2 mag. This comet was more representative than another one occurring in that time – Austin.
1990 – Total lunar eclipse in Krosno. There was a bright eclipse with a 3-4 Danjon Scale. The observation was successful in spite of partial cloudiness.
1993 – Grazing solar eclipse observation. The grazing solar eclipse occurs more or less with the same frequency as the total one at a certain location. During that observation Moon covered the Solar disk for around 24 minutes only, giving around 1% obscuration.
1994 – Partial solar eclipse observation, which was unique because the members of the Krosno branch managed it from the Sucha Góra TV tower making it the highest located PSE 1994 official observation in Poland at that moment.
1999 – Total solar eclipse expedition, Mako, South Hungary. It was a 3rd reported total solar expedition managed by members of the Krosno branch. Except for a few persons, who went to Mako another stuff decide to watch the eclipse from different locations: Wacław Moskal went to France and Mariusz Świętnicki to Balaton. Both Mariusz Świętnicki and a group from Makó (except for Gregorz Kiełtyka, who measured temperature changes during the eclipse) were successful because they caught a clear section of sky with the eclipsed Sun.
2003 – Transit of Mercury was very interesting and gathered around 30 people in Krosno. The transit lasted around 5 hours.
2003 – Partial solar eclipse, that occurred during the sunrise. It was a very nice looking phenomenon with crescent Sun rising above the mountainous horizon of the Dynowskie Foothills.
2004 – Transit of Venus, Jaslo. It was a first observation, which took place with pupils from Primary School Complex No 3 in Jaslo. This school was one of the several places in Poland, where the Transit of Venus observation was carried out officially.
In general, the Krosno branch of Polish Society of Amateur Astronomers carried out many observations of star & planet occultations, grazing occultations, and conjunctions. The most active members in that time were Józef Lubas, Gregorz Kiełtyka, Witold Kosiek, Jacek Adamik, Wacław Moskal, Wiesław Słotwiński and Mariusz Świętnicki.
3. Chairmen and the most active members
Jan Winiarski – a founder and chairman of the Krosno branch of Polish Society of Amateur Astronomers from 1968 to 1983. He was the biggest astronomy popularizer in the Krosno region in the post-war period.
Witold Kosiek – a chairman from 1983 to 1990. He made a Newton telescope 250/1560mm by himself. Due to this, he was able to involve tens of people in astronomy and start to carry out much more technical observations.
Grzegorz Kiełtyka – a chairman between 1990 and 2011, who used to watch the comets and stars occultations. This is a person, who got in touch with Neil Armstrong through the Sky &Telescope magazine and next to David M. Quint – an amateur astronomer from Atlanta, GE. David was able to meet Neil Armstrong, who gave his own autographed portrait for Grzegorz signed: “To Gregory Neil Armstrong”.
Józef Lubas – an active member, who observed many occultations, eclipses and comets. One of the most interesting observations managed by him was Sirius heliacal rising in late August.
Wacław Moskal – astronomy popularizer and Comet watcher. He carried out the Halley’s Comet observation with other members of the Krosno branch. The results were published in “The Archive of the Amateur Observation Network of The International Halley Watch Vol 2”. Chairman since 2012. Now he is a cooperation leader with Primary School Complex No 3 in Jasło.
Mariusz Świętnicki – astrophotographer and astronomy popularizer. He carried out a fantastic total solar eclipse observation on Balaton in Hungary leaving the thunder front behind a few hours earlier.
Wiesław Słotwiński – He is a priest from Królik Polski with big love to astronomy. He carried out many observations of eclipses, occultations, and comets.
4. The most actual period with my membership.
Now let’s see the newest history of the Krosno branch of Polish Society of Amateur Astronomers, which covers the period since 2012, with a new chairman – Wacław Moskal.
This time is fruitful cooperation with pupils from the Primary School Complex no 3 in Jaslo aimed at the asteroid-hunting mainly. The cooperation of the Krosno branch with this school has been running since 2004. It’s worth to mention, that this branch of Polish Society of Amateur Astronomers is located in Stanislaw Leszczynski Secondary School No 1 with an astronomical observatory at the top of the building since 2011.
The astronomical observatory in Jasło is one of the biggest school’s observatory in Poland with 5,2 m dome. It has been built in 2010 thanks to the “The Carpathian Sky” project.
The Krosno branch includes a dozen or so active members, a few of them were listed above.
Taking a glance for the most remarkable activities of the Krosno branch during this time is worth to list:
2013 – The comet C/2011 L4 Pannstars observation
2014 – The Supernovae in M82 observation was carried out during the foehn wind, that impacted on the photo sharpness, though the result was still awesome!
2014 – The opposition of Mars observation shown fantastic details of the Red Planet with a Phobos moon. The observation was led by Mariusz Świetnicki and Jacek Adamik.
2014 – The comet C/2012 K1 Panstarrs observation
2015 – The Mercury and Venus conjunction observation usually happens rarely in Poland due to longitude. In January 2015 Mariusz Świętnicki was very lucky to see both planets in the 38 arcmin distance.
2015 – The comet C2014 Q2 Lovejoy observation
2015 – Partial solar eclipse observation was carried out in a few locations. I also attached my report from Scotland (see details here).
2015 – Asteroid hunting within the Pan-STARRS program cooperation. It was a great success of pupils from the Primary School Complex No 3 in Jasło, who has been taking part in many asteroid-hunting projects. That time they discovered 3 new asteroids. In general, they used to discover a few new asteroids per year.
2015 – Total lunar eclipse observation was observed mainly from Jasło, Krosno, and Zręcin. I sent my report from Cambridge (see details here).
2015 – The Aldebaran occultation observation was carried out in astronomical observatory in Jasło. I was fortunate to take part in this event. Personally, this occultation was perfect for me, because I saw the moment when Aldebaran disappeared behind the Lunar disk.
2016 – The comet C/2013 US Catalina observation was quite easy because this comet became 4th the brightest object on the night sky.
2016 – The transit of Mercury observation was led by members of the Krosno branch in a few places. I also attached the results of my observation from Aylesbury (see details here).
2016 – The “Astronomy in school” international conference in Jasło, where the Krosno branch had the pleasure to meet Sanjay S. Limay from the University of Wisconsin in Madison.
2017 – The Queen Jadwiga Astronomical Observatory day trip with visiting the space garden. There were mainly the pupils from the Primary Complex School No 3 in Jasło, members of the “Per Aspera ad Astra” school club.
2017 – The Gamma Taurii grazing occultation and Aldebaran occultation in daylight observation. A few members of the Krosno branch went near to Dębica town in the western part of the Subcarpathian Voivodship to see this grazing occultation. They used the CCD cameras to report the phenomena.
5. My involvement in the Polish Society of Amateur Astronomers.
I joined to Krosno branch of Polish Society of Amateur Astronomers in 2012. My actual involvement in these organizations based on my 3 projects:
- The Gregorian Calendar, how to use? – already finished and referred during the LVI astronomical meeting on 22.11.2014.
- Pic. 33 I am showing how to use the Gregorian Calendar for long-term periods, 22nd November 2014, phot. Wacław Moskal.
As a result, I created a few long-term calendars for the 1601-4000 period (learn more here).
- Solar & lunar eclipses with strong focusing at the light distribution and changes in the atmosphere (learn more about it here).
- Twilights with a concentration on the influence the twilight duration on the variability of the electricity consumption and impact on the astronomical observations on various longitudes (learn more about it here).
Once I finish those projects I will start doing the next ones for sure. Everything will depend on the ideas, spare time and equipment. Both the Krosno branch and the whole Polish Society of Amateur Astronomers are a great place for self-development, meeting awesome people and taking part in fantastic adventures.
