R-19, Nordhausen ALG Location needed

I am looking for the location of R-19 advanced landing ground (ALG) at Nordhausen, Germany. I have the history and daily diaries of the 438th Troop Carrier Group for WWII. There is no mention of the actual location of the ALG other than they went to R-19 at Nordhausen to ferry french forced laborers. I have looked up the Airfield number in the "U.S. Army Air Forces Continental Airfields (ETO) D-Day to V-E Day" report but there is only the city location mentioned. Does anyone have Google map coordinates for this ALG? Does anyone know where I could find information that would give me the physical location (longitude/latitude) of this airfield? There is a glider field there today but I don't know if that is the same airfield.
Thanks for your help.
I was not sure if this should go in Commands,bases, and stations  or in TC.  Were ALG stations?
