The fourth season of Stargate Atlantis marches onward, with just two episodes left to air in the United States. Today SCI FI Channel announced the ratings number for “Trio,” the sixteenth episode of the season.

“Trio” earned a 1.1 average household rating when it premiered in the U.S. on February 8. This is even with the ratings for the previous week’s episode, “Outcast.”

Atlantis was once again the top-rated original drama series for the cable network, and again was behind the reality series Ghost Hunters International (1.6) and ECW wrestling (1.3).

The second half of Atlantis‘s fourth season continues to average slightly higher ratings than the first half.

Don’t miss this week’s “The Kindred, Part 2,” which concludes the story started in last week’s episode, Friday at 10 p.m. (9 Central) on SCI FI! Learn more in GateWorld’s Season Four episode guide.
