How alerts work

One Kp choice. The recommended level uses your chosen location. Choose a different Kp if you want; save browser settings again if they were already active.

Browser then email. A linked browser is primary. If it does not confirm requesting a visible alert within 15 minutes, one backup email is attempted. A lost receipt can cause both to appear; the site cannot prove what the operating system showed. Without a linked browser, a qualifying forecast email arrives around 16:00 local time.

Limits and control. Fresh Kp data, the aurora oval and dark sky qualify browser alerts; clouds and Moon are not checked. Browser alerts are limited to one per local night, at least six hours apart, and expire after 90 days unless renewed. Unsubscribe or delete your email from any message.
