Your help finding real observations on Twitter when activity is high will help Aurorasaurus generate accurate nowcast predictions

• Select YES if the tweet is a real sighting from a person who has just seen aurora AND if the location appears correct
• Select NO if it is a retweet, clearly has the wrong location, does not refer to a recent sighting, or is a tweet aboutsomething unrelated to the northern lights
• If you aren’t sure, click NO, but if you are reasonably sure, please click YES
• Note, tweets may be unsuitable for some users, please use at your own discretion
