| Słoneczna fala radiowa 2-02-2013 19:54 UTC |
| Dzięki za link z nagraniem. Czyli że co.... z tekstu wynika, że nie przewidziano tak wielkiej aktywności w naszą stronę? Yesterday, Feb. 2nd, the solar activity forecast called for "quiet." In fact, says amateur radio astronomer Thomas Ashcraft, "it was really loud. There were several strong solar radio emissions including one super-strong Type III burst at 1954 UT. I captured it at 28 MHz and 21.1 MHz as it totally drowned out a short wave voice transmission." |
