Rose pinkish orbs in Tempe, Arizona.I have a view to flight path of Sky Harbor airport and often watch incoming planes from my upper deck. On this day, I noticed a rose/pink colored orb in the area where planes are normally in a holding pattern. I watched it head south in my direction, then made an ubrupt turn to east (opposite direction from airport) and watched until it disappeared. I then looked back to where I originally saw this, and saw two more coming! I ran downstairs to get binoculars and by the time I got back upstairs, those two orbs went into same pattern/direction as the previous one. Then, again, two more come into view - from the same direction and eventually disappeared into the eastern sky. I did manage to get a picture. I didn't know what to make of it, but what I find most interesting that no planes landed or were in holding during this time. Once the orbs were gone, planes were again in view and started landing. Very strange.
