Bintik matahari: Perbedaan antara revisi

Bintik matahari, yang merupakan manifestari aktivitas magnetis hebat, juga merupakan tempat terjadinya lengkung-lengkung korona (coronal loops) dan peristiwa pemautan kembali (reconnection events). Kebanyakan lidah semburan matahari dan semburan massa korana berasal di daerah magnetis aktif sekitar kelompok bintik-bintik matahari yang tampak. Fenomena sama yang diobservasi secara tidak langsung di [[bintang]]-bintang dinamai bintik-bintik bintang. Keduanya, bintik terang and bintik gelap telah diukur. <ref name="strassmeier">[http://www.aip.de/groups/activity/presse/pressrelease990610.html press release 990610], K. G.
