we all looked up and there wasn't a rainbow in site just a beautiful sunny evening with a scattering of clouds, she insisted she could see a rainbow, so after cajoling I lay on the bench and blow me down if I could see the fragment of a rainbow amongst the cloud base, blimey you are right I exclaimed and we tried to figure out how this might be in a sky with no hint of rain. One of the girls muttered something about rain droplets in the sky, or ice crystals.
Later more people came to lie on the cloud bench which was proving to be very popular, I got talking to a woman as she was waiting and she said, " did you see the Parhelion tonight" of course I had to ask her what a Parhelion was, and very basically it is ice crystals in the autumn cooling sky that gets hit by the sun and produces a spectrum usually in pairs.
Of course I was able to exclaim "yes, you bet" and in a rather over excited schoolboy fashion I blathered on about how we saw it, I then of course went off to find the three young woman and told them of their find. Naturally they were delighted to hear of such a phenomena and that they had seen it.
There are many reasons why everyone should own a 'cloud bench' anyway, but I feel that this has strengthened my position and expect the commissions to rush in: so please email me at email@example.com with your orders.
the wikipedia definition of a Parhelion is:
A 120° parhelion (plural: 120° parhelia) is a relatively rare halo, an optical phenomenon occasionally appearing along with very bright sun dogs (also called parhelia) as ice crystal-saturatedcirrus clouds fill the atmosphere. The 120° parhelia are named for appearing in pair on the parhelic circle ±120° from the sun.
