Aurora Borealis on 5 May 2024 from Z\u00e1ho\u0159ice, Czech Republic<\/p><\/div>\n

Last night, on May 5th, 2024, the aurora surprisingly appeared even in the Czech Republic, a European mid-latitude country. I observed from Z\u00e1ho\u0159ice village. There were two prominent peaks – after local midnight (after 10 pm UT) and before local 2 am (before midnight UT). Both were visible even to the naked eye, despite the cirrus clouds. This was caused by the strong solar flare produced by hyperactive sunspot AR3663<\/a> on May 3rd, 2024, which also hurled a coronal mass ejection cloud partly to Earth. Actually, this sunspot was much more active; perhaps this is not the last aurora visible from the country this week. Well, what a surprise! <\/p>\n

Used Canon Ra. Wider images were taken at ISO 4000, 15s, 35mm, f2.0, closer views at ISO 3200, 10s, 50mm, f1.4. <\/p>\n
