Prehod Merkurja pred Soncem: 9. maj 2016, med 13:12 – 20:40

V ponedeljek, 9. maja 2016, je Merkur prvič po 7. maju 2003 spet potoval pred Sončevo ploskvo. V srednji Evropi je prehod potekal med 13:12 in 20:40 po poletnem času.

Glede na velikost Merkurja, katerega navidezni premer je skoraj 160-krat manjši od Sonca med prehodom, planeta ni mogoče videti s prostim očesom niti s posebnimi očali, ki se uporabljajo ob Sončevih mrkih.

Da bi opazili to čisto majhno piko pred orjaškim Soncem, je potreben daljnogled ali vsaj manjši teleskop s filtrom za varno opazovanje Sonca.

Mi smo Merkurjev prehod pred Soncem opazovali z napravo, ki se ji reče kamera obskura (lat. “temna soba”). Več o načinu delovanja kamere si preberite tukaj.

2nd project meeting in Gorlice / Poland

Reporting by Sara Vehovar & Zala Gazvoda

The arrival day

On the 2nd April 2016 an adventurous crew from Franjo Malgaj Primary School set sail to Poland. We got to Vienna by a school van and from there we continued our journey by a train to Krakow. The night on the train was pretty interesting, but it was really great that we managed to sleep on it. In Krakow we spent most of our time in a café, playing a game called “Kaj bi bilo, če bi …”.

We took a bus from Krakow to Gorlice. That was our least comfortable way to travel, but still we all took a short nap on it, which gave us strength for the meeting with our hosts. It was a close cut because otherwise we wouldn’t even make it to Gorlice since our beloved teachers lost their orientation. Even when we finally got to Gorlice we didn’t go off on the correct bus stop, so we had to take a short walk around Gorlice. When our amazing hosts came to us our paths separated. Some of us went for a walk, others to the local church for a concert, and some were only eating at their host’s home.

1st day

It is the second day in Poland.

At first we came to school by cars, buses, on foot or any other way. Then we met again. We officially opened the meeting in Poland. They showed us their 110 years old school and we learned a lot of new things about Poland. Then we went for a short walk through their classrooms. Afterwards we had some free time to play volleyball, basketball and other fun activities. But the fun had to end because we were divided into groups and went to the classrooms for english lessons. There we were together with students from the third year and they were solving working sheets with us. We were also talking about ourselves.

Around 1 p.m. we went to a restaurant named “Dark pub” for lunch and we physically prepared ourselves for the game, which our hosts prepared for us. We were in different groups again and we went for a short orientation around Gorlice which lasted two hours. It was very funny and during the game we met a lot of people. After this game, they announced the winner and we were free to go home but of course nobody wanted to do that, so most of us went to a restaurant and then to the store to get some food and drinks for tomorrow. But at last we had to, although not happy with it, separate and slowly go home.

2nd day

The third day of our mission has sadly already passed now. It was quite exhausting since it started at 7.30 am, and ended at about 11.00 pm. We went to Krakow with our favourite thing to travel with – the bus. This way was much more comfortable than the first one although it took us two hours. A guide showed us around Krakow and presented interesting history. We were free for almost four hours, so we took a bite of pizza and kebab. Then we bought some souvenirs for our families and took a short walk around the park. We went to a small town Niepolomice where we observed the Sun, Jupiter and its moons. We were also in a small planetarium where we all almost took a short nap. We ended our day with a ride back to Gorlice and we went totally exhausted and full of amazing adventures into our beds.

 

3rd day

 

Today we were able to sleep longer because of the handful Tuesday. At school there was a conference about light pollution. We were introduced to problems of astronomers because of it and how to fix the problem. We also had a contest for the best “Turn off the lights and save energy” poster. The judges from Slovenia were mr. Jure and Zala. Sadly none of the Slovenian posters got an award.

Meanwhile the rest of us went to workshops to create spectrograms and solar dials.
Because today we also didn’t want to separate right after the official ending,  we went to the restaurant together and afterwards the bowling. But that also ended and we had to go back to our comfortable beds.
4th day
Today we started the day with two very interesting presentations about astrophotography
and history of the private observatory near Gorlice. Since we were so excited about it, we
looked at the Sun, its explosions and sunspots.
We had four hours for lunch and other activities at home, then we had to go back to school
and drove towards small village Radocyna by bus. This village is only four kilometres away
from the border with Slovakia. There we were also looking at the sun and calculated its
activity. Then the teachers were so generous to leave us to do what we wanted, so we
played volleyball. Because we were cold, we roasted sausages on the fire. We were still
hungry, so we afforded ourselves Russian dumplings. We returned home pretty late, but still we had to pack our suitcases, since there will be no time on Friday.

5th day

In the morning the hosts gave us certificates for cooperation and also memory gifts. We drove to tourist place Krynica that is known for winter and spa tourism by bus. We ascended to Parkowa Mountain by drag lift and there we had lunch together in magnificent ambience. The time for our departure was approaching that is why we had to say goodbye to all participant teams. Farewell was really touching since we have spent marvellous and creative week together full of positive energy. We drove to Krakow by bus and then by train to Vienna. Our school caretaker was already waiting there for us  and then he drove us home by van.

 

2. mednarodno projektno srečanje / Gorlice / Poljska

Dogajanje na srečanju v Gorlicah opisujeta Sara Vehovar in Zala Gazvoda.

Dan prihoda

Drugega aprila smo se nadobudna ekipa OŠ Franja Malgaja Šentjur in trije naši mentorji podali na Poljsko. Do Dunaja smo se odpravili s šolskim kombijem, od tam naprej pa smo pot nadaljevali z vlakom do Krakova. Pot z vlakom je bila precej zanimiva, vendar je bilo res super, saj smo lahko spali. V Krakovu smo večino časa preživeli kar v kavarni ob igranju igre Kaj bi bilo, če bi…. Iz Krakovega do Gorlic smo se odpravili z avtobusom. To je bilo naše najmanj udobno prevozno sredstvo, vendar smo tudi na njem zadremali in si nabrali moči za srečanje s svojimi gostitelji.

Malo je manjkalo, da do Gorlic sploh ne bi prišli, saj so naši preljubi učitelji izgubili orientacijo. A tudi ko smo prišli v Gorlice, nismo izstopili na pravi postaji, zato smo morali malo popešačiti. Ko so po nas prišli naši čudoviti gostitelji, pa so se naša pota ločila. Nekateri smo šli na spehod, drugi na koncert, tretji pa na večerjo.

1. dan

Misija Poljska poteka sedaj že drugi dan. Najprej smo se z avtomobili, avtobusi, peš ali na kateri koli drug način odpravili v šolo, kjer smo uradno odprli srečanje na Poljskem. Ogledali smo si njihovo 110 let staro šolo in se naučili veliko novega o Poljski. Šli smo na kratek obhod po učilnicah, potem pa smo imeli nekaj prostega časa za igranje odbojke, košarke in za druge zabavne aktivnosti. A tudi zabava se je morala končati, zato smo se razdelili v skupine in odšli v učilnice k pouku angleščine. Tam so se nam pridružili učenci tretjega letnika, ki so skupaj z nami reševali razne delovne liste. Okoli 13.00 smo odšli na koslilo v “Dark pub”, kjer smo se fizično pripravili na igro, ki so nam jo pripravili gostitelji. Zopet so nas razdelili v skupine in odšli smo na krajšo orientacijo po Gorlicah, ki je trajala kar dve uri. Bila je zelo zabavna in na njej smo spoznali veliko novih ljudi. Po igri so razglasili zmagovalce in počasi smo se odpravili proti domu, saj nas jutri čaka ogled Krakowa in nočno opazovanje neba na observatoriju v Niepolomicah.

2. dan

Sedaj je na žalost potekel že tretji dan naše misije. Bil je kar naporen dan, saj se je začel že ob 7.30, končal pa šele okoli 23.00. V Krakov smo se odpeljali s svojim “najljubšim” prevoznim sredstvom – avtobusom. Ta pot nam je vzela kar dve ure, vendar je bila precej boljša kot tista v nedeljo. Vodička nas je popeljala po Krakovu in vsej njegovi pestri zgodovini. Prosto smo imeli skoraj štiri ure, zato smo si privoščili pico in kebab, za svoje družine nakupili spominkov in odšli na kratek sprehod po parku. Odšli smo še v manjše mesto Niepolomice, kjer smo opazovali Sonce, Jupiter in njegove lune. Bili smo tudi v planetariju, kjer smo skoraj vsi malce zadremali. Dan smo končali z vožnjo do Gorlic in čisto izmučeni od vseh čudovitih doživetji odšli v posteljo.

3. dan

Danes so nam zaradi precej napornega torka pustili spati malo dlje. V šoli smo najprej imeli konferenco o svetlobnem onesnaženju. Tam so nam predstavili težave tega onesnaženja za astronome, ter kako jih lahko odpravimo. Zala in učitelj Jure sta bila v komisiji za izbiro najboljšega plakata “Turn off the lights, save the energy”, vendar na žalost noben od slovenskih ni dobil priznanja. Med tem časom smo ostali izdelovali  spektrogram in sončno uro. Ker se tudi danes nismo želeli ločiti takoj po koncu programa,  smo skupaj odšli v restavracijo in na bowling, kjer smo se zelo zabavali. Kot vsaka dobra stvar, se je tudi ta končala in vsi smo odšli domov in tudi slej ko prej v posteljo spat.

4. dan

Danes smo dan začeli z dvema zelo zanimivima predavanjima o astrofotografiji in zgodovini observatorija blizu Gorlic. Ker so nas tako navdušili, smo si odšli ogledati Sonce, protuberance na njegovem površju in sončne pege. Po kosilu smo morali nazaj v šolo, kjer nas je pobral avtobus. Z njim smo se odpeljeli vse do majhne vasi imenovane Radocyna, ki je od Slovaške oddaljena le dobre štiri kilometre. Tam smo spet opazovali Sonce in opazovali njegovo aktivnost. Ob tem so bili učitelji tako radodarni, da so nam pustili prosto, zato smo šli igrati odbojko. Ker nas je zebelo, smo zakurili ogenj in si spekli klobase. Ker se le teh nismo najedli, smo si privoščili še ruske pieroge. Domov smo se vrnili precej pozno, a kljub temu smo si pred spanjem morali še spakirati.

5. dan

Dopoldne so nam gostitelji podelili potrdila za sodelovanje in izročili spominska darilca. Z avtobusom smo se odpeljali v turistični kraj Krynica, ki je poznan po zimskem in zdraviliškem turizmu. Z vlečnico smo se povzpeli na hrib Gora Parkowa, kjer smo v prečudovitem ambientu imeli skupno kosilo. Ker se je bližal naš odhod, smo se poslovili od vseh sodelujočih ekip. Slovo je bilo ganljivo, kajti preživeli smo čudovit in ustvarjalen teden, prežet s pozitivno energijo. Z avtobusom smo se odpeljali do Krakowa, od tam z vlakom na Dunaj, kjer nas je že čakal naš hišnik, ki nas je s kombijem odpeljal domov.
