Solar activity
Sunspot regions, coronal holes, filaments? In this forum we discuss everything related to the activity on our nearest star.
Solar activity forum rules - Let's keep things tidy!
1. Want to talk about a sunspot region? Feel free to make a topic! Keep the title clean and simple! For example: Sunspot region 1234, or AR1234.
2. Want to discuss a solar flare? Do not make a new topic! Post in the existing topic for that sunspot region or make a new topic if the sunspot region in question does not have a topic yet!
3. Solar flares and sunspot regions on the east limb that are not numbered yet are discussed in this topic.
4. Returning active region? Make a new topic with the current sunspot region number. Do not revive the old topic for that sunspot region!
5. Want to talk about coronal holes? There is a dedicated topic for that. Do not post a new topic.
6. Want to talk about filaments? There is a dedicated topic for that. Do not post a new topic.
7. Discussions about possible earth-directed coronal mass ejections and the geomagnetic storm that it might cause go in the geomagnetic activity forum.
