As our users will know, we love Twitter here at Aurorasaurus. In addition to using the social media service ourselves (check out the Twitter list of Aurorasaurus Team Members here<\/a>),\u00a0we present aurora-related tweets for our users to verify them as aurora sightings (a process called crowdsourcing<\/a>.)\u00a0We then use these \u201cverified tweets\u201d in just the same way as the other observations reported via our website or apps, for example, by comparing their location with the modeled auroral ovals.<\/p>\n

In this blog post, we wanted to highlight a recent academic publication we wrote about using Twitter as a tool to map the aurora. For those with access to AGU journals, the study can be found here<\/a>.\u00a0In the study, we looked at how Twitter can provide a picture of when, and from where, an aurora can be seen. As you\u2019ll probably already know, people love tweeting about when they see the aurora (and we love reading those tweets too!). When people do tweet about their sightings, they often include their location (either directly through GPS embedding or in the text of their tweet) and other useful info (such as a photo).<\/p>\n

The study showed that the number of aurora-related tweets correlated well with several different \u201cgeomagnetic indices\u201d. These common, but somewhat confusing, indices are proxies for auroral activity. This means that they are not true measures of auroral activity but as these indices increase so does auroral activity. This showed that as the level of auroral activity increased, and an aurora was visible to more people over a wider area, the number of aurora-related tweets increased.<\/p>\n

Additionally, \u201cpeaks\u201d in the number of aurora-related tweets were found to frequently coincide with particularly strong auroral displays.<\/p>\n

Sounds fairly obvious right? Well, perhaps it is, but it had never been shown before! Similar relationships had been found with many other phenomena (such as earthquakes and influenza outbreaks) but this was the first time a study had looked at using Twitter as a tool for mapping the aurora.<\/p>\n

So, remember, if you see an aurora then please let us know either via our website or mobile apps, or post about your sighting on Twitter. If you do post on Twitter, always be sure to post promptly (don\u2019t wait until the next day) and to include your location (by turning on Tweet Location or being very clear in the message of your tweet).<\/p>\n

The study has received coverage on LiveScience<\/a> and the Smithsonian Institute<\/a>.\u00a0\u00a0We are excited to help demonstrate one of the many ways citizen-science data can be used for scientific purposes.<\/p>\n
