A new layer has been created. You could define the projection information for this temporary layer, but as we cannot edit it further at this stage, we will convert it first into a shapefile. Right click the layer in table of contents (TOC) and "save as shapefile". Store the shapefile in your work folder.

Delete the temporary layer from the TOC and add the shapefile you just created. Right click and define the projection in Properties (Massachusetts Mainland State Plane (Lambert Conformal Conic), NAD 83). Now your points should fall in the "right places" in the UMASS orthophoto.
