The stone is a part of the collection found during the fourth season of micrometeorite findings/verification in populated areas (2018). The catalogue number refers to the NMM archive (the main index of Norwegian Micro Meteorites, Jon Larsen’s urban Stardust Collection), and the stone was found and curated by Jon Larsen.
VERIFICATION: The MM has been confirmed extraterrestrial by SEM/EDS analysis and visual identification by Jon Larsen, and is a verified micrometeorite, hereby confirmed in writing. The stone is delivered with a Certificate of Authenticity incl. classification, a signed label, plus one digital color photo.
