when I download a base map (Imagery) to my data frame does not georeference as my data frame

[RitaPinto_de_Teal]

is this a bug?

should I transform all my data to WGS84? O is there a way to fix this?

Rita,

Are you trying to georeference your data or is it already georeferenced?

Which projection are you using?

Did you define a coordinate system for the dataframe or map before adding the basemap?

The first layer added determines the coordinate system, so if it is undefined things can go wrong
