All my meteorologist friends were talking about the picture of four rainbows captured by Amanda Curtis while she was waiting for a train on Long Island earlier. Some media outlets called it a quadruple rainbow, but after looking at the optics, it was determine instead to the a double rainbow accompanied by a double reflected rainbow. You can read the description, including a comment by UGA Physics professor Craig Wiegert, at https://bigstory.ap.org/article/1f2c34da5c7b454fba4416a70f7c4968/weird-4-rainbows-photographed-not-quadruple-rainbow.
WeatherUnderground has a similar story on the science behind the photo at https://www.wunderground.com/blog/JeffMasters/comment.html?entrynum=2963&cm_ven=FB_BLOG_LB_042115_5
One clue is that the two sets of arcs appear to have different centers. Because of the way the optical effects work, only one set of two rainbows could have come directly from the sun, and thus the other two came from a reflection of the sun on a puddle or other body of water or shiny surface. A fantastic and serendipitous shot!
