Orange sphere with alternating sound, 30 feet in diameter

I was at a phone booth, there was a alternating sound that was interupting my conversation over the phone, I went outside and looked for ambulance or something there was nothing, went back inside and the sound continued at a higher frequency and much louder my girlfriend could berely hear me I went outside again and looked up and there it was, a round sphere 50 feet above the booth maybe 30 feet in diameter the sound would alternate with the brightness, the freequency of the glow and noise increased to unberable , I went into my car and took off, whent home and looked out the window toward the north east I could see the object going slow into the clouds and the orange light reflecting on the clouds, the freequency had slowed, it was about 4:00 am when I got home, there was a time lapse.
Witness indicates that the date of the incident is approximate.  PD
