This is an excerpt from one of the interview transcipts provided by Matilda O'Donnell MacElroy which are duplicated in the book, Alien Interview:

Official Transcript of the U.S. Army Air Force, Roswell Army Air Field, 509th Bomb Group

SUBJECT: ALIEN INTERVIEW, 25. 7. 1947, 1st Session

"...The Domain Expeditionary Force first entered into the Milky Way galaxy very recently -- only about 10,000 years ago. Their first action was to conquer the home planets of the "Old Empire" (this is not the official name, but a nick-name given to the conquered civilization by The Domain Forces) that served as the seat of central government for this galaxy, and other adjoining regions of space. These planets are located in the stars systems in the tail of the Big Dipper constellation. ( See Footnote below)   She did not mention which stars, exactly."

"... the Big Dipper constellation..."

"Within Ursa Major the stars of the Big Dipper have Bayer designations in consecutive Greek alphabetical order from the bowl to the handle.

Proper
Name
Bayer
Designation
Apparent
Magnitude
Distance
(L Yrs)
  Dubhe     α UMa       1.8    124
  Merak     β UMa       2.4      79
  Phecda     γ UMa       2.4      84
  Megrez     δ UMa       3.3      81
  Alioth     ε UMa       1.8      81
  Mizar     ζ UMa       2.1      78
  Alkaid     η UMa       1.9     101

 Near Mizar is a star called Alcorr and together they are informally known as the Horse and Rider. At magnitude 4.1, Alcor would normally be relatively easy to see with the unaided eye, but its proximity to Mizar renders it more difficult to resolve, and it has served as a traditional test of sight. In the 17th century, Mizar itself was discovered to be a binary star system — the first telescopic binary found. The component stars are known as Mizar A and Mizar B. In 1889, Mizar A was discovered to in fact be a binary as well, the first spectroscopic binary discovered, and with the subsequent discovery that Mizar B itself is also a binary, in total Mizar currently is known to be at least a quadruple star system."
