Yet another XY out of place question.

Imported Excel table with XY coordinates.

Coordinate system for point layer is the same as the data frame.

When XY event is created in ArcMap points are about 150 miles from where they should be.

When XY are plotted in Google Maps they are in the correct position.

It's been a long day and can't think of any rationale reason as to why this is occurring. Any ideas/insight greatly appreciated.

are the coordinates in decimal degrees? degrees decimal minutes? degrees minutes seconds? Projected?

Did you try using the Excel to Table tool to bring in the excel data?

Do you have a few sample points you could post?

What is the coordinate system that is being used?
