HERE ARE (VERY) OLD SLIDE SCANS. SLIDES WILL BE RE-SCANNED, IMAGES ENLARGED AND NEW SLIDES SCANNED IN FUTURE.
2003 there was a nice NE wind for a couple of days during high pine pollen amounts - 11th Jun first row and 14th Jun the rest of the images. As soon as the wind died (or turned to blow from sea) then also pollen coronas were gone.
Note how some images show ordinary iridescence on clouds.
In some images with this resolution pollen corona is not visible too well because I tried to catch also the churches in full. In larger size the phenomenon is - of course - clearly visible.
