Found and interesting potential meteor this morning.
A Slow Class Ia- with a complex tail.
A bit of analysis with low and band pass filters suggests it is possibly 2 bodies: one a Class IIa- and the other a class IIa+ or * (* is indeterminate).
The Dominant Signal Period (and hence the Dominant Signal Frequency) is a function of the particle size, not just it's speed. The DSP is determined by the time taken to close the vacuum behind the super sonic particle, so both speed a size have an effect. Given that 2 particles travelling together will have the same speed, their DSPs will reflect their relative sizes.
In this case the larger particle (Class IIa-) had a DSP of 0.414s while the smaller particle had a DSP of 0.221s.
