<<<Dr. Hwang, "...May I know what is the direction of the sun when you saw the rainbow? Is there any other strong light source around?">>>

I do not remember the time of day, but think it was early afternoon. The attitude of the bow was approx NE to SW, me being on the SW end of the bow. The sun was shinning at my location and the rain clouds were just to the East of me.

There was no other light source.
