A white rainbow is called a Fogbow, as photographed by Jon Shiu.

Jon Shiu saw this Fogbow and said it only lasted a few minutes. It's a treat to see one, as they don't happen very often.

Here's some information from EarthSky.org regarding this phenomenon:

"Fogbows are sometimes called white rainbows, or cloudbows or ghost rainbows. They’re made much as rainbows are, from the same configuration of sunlight and moisture. Rainbows happen when the air is filled with raindrops. You always see a rainbow in the direction opposite the sun. Fogbows are much the same, always opposite the sun, but fogbows are caused by the small droplets inside a fog or cloud rather than larger raindrops.

Look for fogbows in a thin fog when the sun is bright. You might see one when the sun breaks through a fog. Or watch for fogbows over the ocean.

Because the water droplets in fog are so small, fogbows have only weak colors or are colorless."

Look for a fogbow in the morning! I saw one once when Rick and I were traveling down Highway One. After Rick pulled over, I tried to take a photo but my camera wouldn't focus on it! Rick, being more experienced, took over and manually focused to get the photograph. And in a minute or two, the fogbow was a memory.

Thanks to Jon for allowing me to share his photo with you here.

Rain and more rain today! I'll report on the totals tomorrow. But we are fast approaching the total of all last season, which is great news.
