Vybavení doporučené pro astronomická pozorování - Astro.cz
Pro začátek stačí menší triedr (ten se lépe drží v ruce), v astronomii je často používaný 10×50. S triedrem se naučíte základní orientaci na obloze a poznáte ...

V sobotu 8. června došlo na Slunci k silné erupci téměř nejvyšší kategorie X. Nastala v nejzajímavější aktivní oblasti AR3691 (před měsícem jako AR3664 způsobila nejhezčí polární záři za desítky let). Oblak hmoty, který byl vyvržel do kosmu, míří okrajovou částí i k Zemi a může dojít k polární záři někdy v pondělí. Je těžké toto předpovědět, sledujte např. <anchor>Spaceweatherlive.com</anchor>. Nejzajímavějším doprovodným jevem této erupce je neobvykle silná radiační bouře (už na stupni S3 z pěti možných). Neobvyklé je i množství velmi vysokoenergetických protonů nad 100 MeV.
