First time I remember seeing one in Karachi was way back in 1979 (when I was a toddler). That Rainbow was a lot thicker and brighter then this one. Probably because it was against a very dark cloudy background. And now (after 31 years) I got to see this one!
I also saw the total solar eclipse we had in Karachi. August of 1999 it was, unfortunately I didn’t have a digital camera at the time - And my film camera really let me down that day… But I will forever remember that sight, which lasted for 1 minute and 18 seconds!
