Spectacular solar halo this afternoon in Gavà, in Baix Llobregat, already announcing the desired rains for these next few days that we hope will help alleviate the drought in Catalonia. Happy rain!
In this series of images in La Vanguardia Readers' Photos we can see the solar halo in detail and also over emblematic places in Gavà, such as the City Hall headquarters. We can also see it in the Gavà Mar area.
The solar halo forms around the sun, presenting an iridescent ring on its outer circumference, due to ice crystals when there are high clouds.
The halo is caused by ice particles suspended in the troposphere that refract light, generating a spectrum of colors around the Moon or Sun.
It is an optical effect in the shape of a disk around the sun - or the moon - and has an iridescent ring on its outer circumference.
