In this most complex of all of our projects snapshots of the winter solstice questionnaires sent 10 teams. As usual, not all participants managed to adequately carry out this complex research. Questionnaire participants from Moscow even had to lock as cloudy weather did not allow to carry out surveillance and fill out the form with zeros in this case is unacceptable because it contradicts the procedure of the project. As in September, we compare our results with the data of the site http://planetcalc.ru/320/
Participants from the village Ostrovskaya Volgograd Region for the second time participating in this project, their data again, quite precise and accurate. On the day of the autumnal equinox the sun was at 41,63 ° above the horizon, and in the winter, it has risen by only 15,73 °.
Data from Moscow and the Soviet are not adequate. But the party in the village Beloyarskii ovalyakina east of Yekaterinburg was quite accurate. The questionnaire contains the height of the sun 9,73 °, and an online calculator shows 8,87 °. Very inaccurate participants from Astrakhan.
The "Sun above the horizon," the most complex of all studies Freeze. This September, the call took six participants. Let's see what they did together and discuss the results of the project.
For example, members of the village Ostrovskaya Volgograd region experimental determination of the height of the sun above the horizon showed 41,63 °. If you look at the site http://planetcalc.ru/320/, the geographical coordinates of the height of the sun is equal to 43,3 °. Given that I can not say exactly what time the measurements accurate enough results. But the magnetic bearing on the website Set 170,3 °, while the participants Freeze counted 330 °. That this result would have been interesting to discuss ...
A more southerly position of the participants still picture from Nizhnekundryuchenskogo rural settlement. Their result - the height of the sun above the horizon 57,94 °. Site http://planetcalc.ru/320/ gives a different result - 47,1 °. This is the maximum height of the sun above the horizon, which is achieved for the entire day at this latitude ... also an interesting topic for discussion ...
Experimental results from Novosibirsk (the most eastern result of the project) is also closely coincides with the calculated 36,40 ° and 34,2 °. With azimuth everything again oddly enough: measured - 344 °, and by calculations leaves - 173,9 °
Participants from Zherdёvka Tambov region during the study to determine the height of the sun above the horizon 39,57 °. If you look at the site http://planetcalc.ru/320/ the height of the Sun 37 °. Match fairly close. And most importantly, it is the only participant who was close to the calculated value of the magnetic azimuth. According to their observations - 170 °, and the site - 177.9 °.
In our northern members altitude of the sun above the horizon, obviously, below. In St. Petersburg - 30,6 °. Under the Archangel in Cecht - 24,90 °.
But with the azimuth but our experienced members of Zherdёvki no one guessed. It would be interesting to discuss how we did it ...
We see a very exact match data calculated by the length of the shadow and the data from the Internet.
The participants of the group "Friends" height of the sun came out 31.6 degrees. Cities Krasnokamsk online http://planetcalc.ru/320/ could not be found, but in the nearest available city of Perm in the height of the sun on this day would have to be 26.77 degrees. It is interesting to try to explain these results ...
If we are going to have a ball on the forehead, it is better, in the form of oblique impact than direct, right? So it is with particles of light - photons; they can be likened to the balls flying at high speed about 300 000 km / s and the amount of energy that they transmit depends on the angle of incidence ... is about the theory behind the fact that by the autumn, when the sun is below the horizon, it is less warms land ... But here's an interesting question ... how plants know that the sun was below the horizon? After cooling takes place in the summer? What is one of the main signals of autumn?
Why do this project, the result of which would seem to be predictable? Position of the sun in the sky at any place, any time and any date can be calculated by astronomical and navigational programs without any whatsoever field observations.
