I originally entered this observation as Solidago ptarmicoides (Oligoneuron album) but am now convinced that it is a Solidaster, a hybrid goldenrod. I was unable to find any way of changing the proposed identification from Solidago ptarmicoides to Genushybrid Solidaster in the original observation.
Images 1-4 show the plant in location. Images 5-9 of the flowers on a dried stem of the observed plant were taken 2023-01-09 with a low power digital microscope. The dimensions of the involucres, phyllaries and petal are about half of the values expected for Oligoneuron album but more in line with Solidago canadensis, S. juncea and Euthamia graminifolia, the other goldenrods found at this location.
