AccessNorthGa.com received calls between 10:00 and 11:00, the first about 10:40 from the McEver Road/Browns Bridge Road area. The caller said it shook her house and wondered if it might have been a sonic boom, caused by a jet breaking the sound barrier.
A second caller, a few minutes later, said he was sitting by his pool on Mountain View Road, which is off McEver, and saw a "streak across the sky," followed by the loud noise, leading to some speculation that it was a sonic boom caused by a meteor entering the earth's atmosphere.
There were also reports Friday morning from people who say they heard it in Monroe and in Lumpkin County.
Lt. Col. James Wilson, a spokesman for Dobbins Air Reserve Base, said the noise was probably not caused by a plane approaching or leaving the base, which is in Marietta. He said the Dobbins flight schedule does not indicate any aircraft would have been passing through the area at that time.
Base officials say they are still looking into the matter.
