ABC’s “The Astronaut Wives Club” perked up on Thursday, rising to the best scores since its premiere and appearing to edge out a slipping “Under the Dome” and “Wayward Pines” as the night’s top drama among young adults. And over at NBC, “Dateline” was a big improvement on “Aquarius” and “Hannibal.”

Univision edged out CBS for the night’s lead in adults 18-49 thanks its coverage of “Premios Juventud” (1.5 rating/6 share in 18-49, 3.3 million viewers overall), according to preliminary national estimates from Nielsen. The “Youthfulness Awards” did a 2.7/13 in New York and a 3.0/11 in Los Angeles.

According to preliminary national estimates from Nielsen, “Astronaut Wives Club” (1.0 rating/4 share in adults 18-49, 4.5 million viewers overall) was up 22% week to week (0.96 vs. 0.79) and placed second for the 8 o’clock hour. It had fallen as low as a 0.7 a few weeks ago, but has now grown two straight weeks. Pending updates, it stands as Thursday’s No. 1 drama in 18-49, slightly ahead of “Under the Dome” and “Wayward Pines.” (Both “Dome” and “Wayward” have a fairly good chance of rounding up to a 1.0 in the nationals while “Astronaut” could revise downward.)

“Astronaut” was followed on ABC by “Mistresses” (0.8/3 in 18-49, 3.3 million viewers overall) and “Rookie Blue” (0.7/3 in 18-49, 3.6 million viewers overall), with the former up 6% (0.84 vs. 0.79) and the latter up 4% (0.73 vs. 0.70). For the night, ABC’s preliminary 0.84 rating in 18-49 is the best in the four weeks since the three-drama lineup began airing.

Elsewhere, CBS won the night’s opening hour with encores of “The Big Bang Theory” (1.4/6 in 18-49, 7.2 million viewers overall) and “Mom” (1.2/5 in 18-49, 5.0 million viewers overall). They were followed by “Big Brother” (2.0/7 in 18-49, 6.0 million viewers overall), which was again the night’s top show and was up a tick from last week, and “Under the Dome” (0.9/3 in 18-49, 4.8 million viewers overall), which was down a tenth. This would either match or set a series low for “Dome.”

NBC’s “Food Fighters” (0.9/4 in 18-49, 3.8 million viewers overall) matched last week’s score, and the time period premiere of “Dateline Mystery” (1.1/4 in 18-49, 5.4 million viewers overall) was more than double the previous week’s 0.4 average for firstrun dramas “Aquarius” and “Hannibal,” which will be airing on Saturdays starting this weekend. “Dateline” placed second in the 9 p.m. hour, and then pulled ahead of CBS and ABC in 18-49 at 10.

CW’s “Beauty and the Beast” (0.3/1 in 18-49, 1.0 million viewers overall) was up 29% from last week (0.27 vs. 0.21) for the best 18-49 score since its season premiere. Moving in the other direction was British import comedy “Dates,” which managed a mere 0.1 rating in 18-49 and about 500,000 for its pair of episodes in the 9 o’clock hour.

Preliminary 18-49 averages for the night: Univision, 1.5/6; CBS, 1.4/5; NBC, 1.0/4; ABC and Fox, 0.8/3; Telemundo, 0.5/2; CW, 0.2/1.

In total viewers: CBS, 5.8 million; NBC, 4.9 million; ABC, 3.8 million; Univision, 3.3 million; Fox, 2.6 million; Telemundo, 1.3 million; CW, 0.8 million.
