I have always believed that rainbows have seven stripes - how can a rainbow have more than 7?
Unless it was a double rainbow, in which case it would have had 14

Solar activity has nothing to do with the rainbows. Its caused by sunlight refracting off falling rain. Nothing more and nothing less.
The height and brilliance of them is determined by the height of the sun at the time of observation. They are at their best during early morning and late afternoon
