Details:
On Sunday 21st, sunset was followed half-an-hour later by a beautiful Sunset Twilight Arch with radiating Crepuscular Rays. This was similar to the previous magnificent display recorded on the Monday 15th with anticrepuscular rays appearing in the east followed closely by a Sunset Twilight Arch with Crepuscular Rays in the West. Cause again, local increases in aerosols of unknown provenance (possibly volcanic eruptions) in the stratosphere. This interesting pattern of bright displays with mediocre ones or none in-between has been observed during previous increases in global volcanic activity and is due to the patchy way the aerosols accumulate and then disperse in the stratosphere and contrasts with those resulting from individual major eruptions such as Calbuco Volcano in 2015 which eject enormous ash and aerosol plumes into the stratosphere that cause months of continuous spectacular sunrise and sunset twilights over substantial portions of the globe.
