470.3125 Mhz

This is a 1-minute audio segment, taken from a Uniden Bearcat hand-held scanner tuned to 470.3125 Mhz. It is part of a 2.5 hour period from 0800-1030 UTC on Nov. 9, 2013.
Included is my SpectrumLab plot as well as the Planetary K index for Nov. 9, 2013.
Can anyone tell me if this audio is a result of the aurora activity at that time? If not, what could I be picking up at that frequency? Thanks.
