David,

I think these are real synchrones. Michael Jaeger has imaged them in a
lot more detail. I've put a stretched version of an image I took this
morning here:

With a bit of imagination you can see four in the dust tail.

Unfortunately we still have quite bright skies at this time of year but,
even so, the dust tail is visible out to around 9 degrees and the ion
tail to 11.5 deg.

Nick.
