When space weather happens, we often make news updates which you can receive in your e-mail. We only send an update if there is interesting news to report like solar flares, coronal holes, geomagnetic storms and a lot more. Everything in regard to Space Weather, so you'll never miss out significant events.
The system will only send out an e-mail if there is news to report, and this will be done daily so that you won't receive a bunch of e-mails from us. During periods of high activity it can be the case that you'll receive an e-mail from us every day, in quiet times it could take more than a week, it all depends on our beloved star the Sun. If you ever want to unsubscribe, use the link in the e-mail, and we'll stop sending you these updates. You can always reactivate them in a later time.
Keep in mind that SpaceWeatherLive is run by volunteers in our free time, it can happen that we can't find the time to write news items, but we do our very best to make sure big events are always posted.Subscribe now!
A lot of people come to SpaceWeatherLive to follow the Sun's activity or if there is aurora to be seen, but with more traffic comes higher server costs. Consider a donation if you enjoy SpaceWeatherLive so we can keep the website online!
