Double rainbow in Heathrow

This is interesting. I saw another double rainbow on my way to Heathrow the next day, This also lasted under a minute. Just enough time to get my phone and go snap, appreciate it for a short moment and it was gone! Then looking at both photos on my photostream, the rainbows in the 2 pictures seem to symetrically line up. I did crop the second one but not for that purpose.

 

According to ChatGPT: "Seeing a double rainbow on two consecutive days has an estimated probability of about 1 in 49,000 (0.002%)."
