Saw what looked to the naked eye as a bright star in the daylight with no clouds. with binoculars it looked like a round or cylindrical bright light moving in the the sky facing ne towards mcas miramar and the wildlife reserve. object was moving what appeared to be east and west over the area, drifting back and forth at a speed that seemed faster than a jet. i was able to view it for several minutes and it appeared to fade behind haze, although there were no clouds in the area. the light appeared to fluctuate due to the haze in front of it and eventually i was unable to see it as it disappeared into the north eastern sky. the light might have been a bright reflection as the sun was going to set in the next few hours, although it was very bright. it seemed to be at a very high elevation, higher than the commercial jets flying in the southern sky at that time. it looked like it might be located over the mission trails wildlife reserve. perhaps it was something out of mcas mirmar?
