På søndag sørget fenomenet “rayleigh-spredning” for et fantastisk fargeshow på himmelen over Brøggerhalvøya. Et sjelden fenomen å se med så stor intensitet.
De sterke rød- og rosafargene på himmelen kommer av lyset fra solen. Solen befinner seg nå omtrent åtte grader under horisonten midt på dagen. Når sollyset treffer det vi kaller polare stratosfæriske skyer, oppstår den såkalte rayleigh-spredningen, forklarer Dag Lorentzen, professor på UNIS. På slike dager er vi heldige som bor i nord.
