This rainbow lasted unusually long. In fact, there was a second rainbow beside it, which is fainter. I think it's the reflection of the first rainbow (if I'm not wrong) and its colours are opposite of the first one. It was still up there after 7pm and disappeared only when the sun set. And I believe it could be seen at many parts of Singapore.
I took this rare opportunity to take a picture of my mother's newly grown roselle plant. I hope they can grow up successfully.
