One more grab before we put this visitor to bed....
I stayed out at the property Sunday night and did one more run on ZTF. Then drove the 160km(100mi) to Canberra for work early this morning. They yellowishness in the dust tail has vanished. I'm wondering if that had something to do with it being just a bit higher in the sky and out of the muck or some preferential colour reflection off the dust at certain angles of incidence, reflection?
