Aurorasaurus citizen science data is a collection of auroral sightings submitted to the project via its website (aurorasaurus.org). It is a robust data set and particularly abundant during strong geomagnetic storms. This data is offered to the scientific community for research use through an open-access database in its raw and scientific formats for the 2014-2025 period, each of which is described in detail in the following technical report: MacDonald, E., Natsheh, F., Brandt Edson, L., & Heavner, M. (2026). Crowdsourced aurora observations during geomagnetic superstorms: The Aurorasaurus open science database. Manuscript submitted for publication to Frontiers in Astronomy and Space Sciences, Space Physics Research Topic: Heliophysics Big Year: Education and Public Outreach Reports.
