What is it about: The “Head in the Stars” channel posted information on New Year's Day that on the night of January 1-2 in our country we will be able to observe the aurora borealis again. The previous one took place only on New Year's Eve. “Listen, it's happening things extraordinary!” – we read.
Perfect conditions for the aurora borealis: According to the author of the post, “yesterday's aurora borealis was just a cover for what has been happening since the morning.” “Looks that the Bz parameters are maintained at -20nT, and this is true perfect conditions for observing the bright aurora borealis” – we read. The aurora is to be “very bright and extensive” and visible in most areas of Poland.
What is the Northern Lights? The aurora borealis is a light phenomenon observed in the upper atmosphere near the planet's magnetic poles. Although it usually occurs at high latitudes, especially above the Arctic Circle, increasing solar activity allows us to observe spectacular aurora borealis also far south of the poles, also in Poland.
More and more frequent auroras in Poland: More frequent observations of the aurora borealis in Poland are also due to the development of technology allows you to receive information in advance about the solar wind approaching Earthcarrying charged particles that cause auroras. Dr. Piotr Witek in an interview with IAR points out that auroras have also appeared over Poland in the past, but now we can better prepare for them and share our observations on the Internet, which in turn causes an increase in interest in this phenomenon.
Aurora colors: To observe the aurora borealis, it is worth going to the darkest possible place, away from artificial lights. Interestingly, colors of the aurora borealiswhich we can see in the sky, are related to the reaction of the solar wind with a particular wind gaslocated in the Earth's atmosphere, and with the altitude at which the reaction occurs. It causes the most frequently observed green and rarer red aurora oxygenpurple – nitrogen, and the rare blue and purple auroras are due to hydrogen and helium.
