From SFN:
Note: At the request of the U.S. Air Force, this broadcast is time-delayed and will end in the event of an anomaly.
So if it ends abruptly we have every right to assume it has failed.

Apogee 651.9 km, Perigee 640.9 km, 71.977 degrees inclination.
Perigee is a little low, and inclination a little high, but they are claimed to be within parameters.
You previously wrote:
"The target orbit for the deployment of the satellites is a circular low Earth orbit at an altitude of 650 kilometres, and with 72 degrees of inclination. "
My calculations:
Perigee 98.6% of expected, which at first looks not so good, but:
Expected orbital period: 5,863.22 seconds
Achieved orbital period: 5,858.72 seconds
99.92%
Three nines for all solid propulsion seems pretty darn good!

I'll go with that. The inclination was a lapse, I had to write pretty much the entire article in four hours whilst also eating and dealing with a couple of other things, and for some reason I remembered it as 350x350x71 instead of 72. 10 km isn't a serious shortfall, but it is still a little low, which was exactly what I said.

Quick note, the O/OREOS was designed, built and is managed by NASA’s Ames Research Center, Moffett Field, Calif. Thanks to AMES PAO for the note!
Strange, a couple of sites said it was Stanford. I guess they must have been confused by Stanford's involvement in some earlier NASA CubeSat missions.

I have some doubts, that the USA designators are correct. It is highly unlikely, that civil satellites like RAX, O/OREOS or FASTSAT-HSV-01 will get the military USA designator. And even the military payloads of this kind (i.e. STP payloads) rarely get an USA designator.

For the record neither STPSat-1 nor any of the previous FalconSats were given a USA designation. Off the top of my head, the only non-US military satellite to receive a USA designation was USA-98, which was a NATO communications satellite.

There's nothing online about whether or not Nanosail-D deployed its sails. In fact... There hasn't been ANY update since it was ejected from FASTSAT last weekend. Is NASA even communicating with the spacecraft? (It's Twitter page, @NanoSailD, went silent right after ejection)

NanoSail-D Ejects: NASA Seeks Amateur Radio Operators' Aid to Listen for Beacon SignalOn Wednesday, Jan. 19 at 11:30 a.m. EST, engineers at Marshall Space Flight Center in Huntsville, Ala., confirmed that the NanoSail-D nanosatellite ejected from Fast Affordable Scientific and Technology Satellite, FASTSAT. The ejection event occurred spontaneously and was identified this morning when engineers at the center analyzed onboard FASTSAT telemetry. The ejection of NanoSail-D also has been confirmed by ground-based satellite tracking assets.
Amateur ham operators are asked to listen for the signal to verify NanoSail-D is operating. This information should be sent to the NanoSail-D dashboard at:
http://nanosaild.engr.scu.edu/dashboard.htm. The NanoSail-D beacon signal can be found at 437.270 MHz.
The NanoSail-D science team is hopeful the nanosatellite is healthy and can complete its solar sail mission. After ejection, a timer within NanoSail-D begins a three-day countdown as the satellite orbits the Earth. Once the timer reaches zero, four booms will quickly deploy and the NanoSail-D sail will start to unfold to a 100-square-foot polymer sail. Within five seconds the sail fully unfurls.
"This is great news for our team. We’re anxious to hear the beacon which tells us that NanoSail-D is healthy and operating as planned," said Dean Alhorn, NanoSail-D principal investigator and aerospace engineer at the Marshall Center. "The science team is hopeful to see that NanoSail-D is operational and will be able to unfurl its solar sail."
On Dec. 6,, 2010, NASA triggered the planned ejection of NanoSail-D from FASTSAT. At that time, the team confirmed that the door successfully opened and data indicated a successful ejection. Upon further analysis, no evidence of NanoSail-D was identified in low-Earth orbit, leading the team to believe NanoSail-D remained inside FASTSAT.
The FASTSAT mission has continued to operate as planned with the five other scientific experiments operating nominally.
"We knew that the door opened and it was possible that NanoSail-D could eject on its own," said Mark Boudreaux, FASTSAT project manager at the Marshall Center. "What a pleasant surprise this morning when our flight operations team confirmed that NanoSail-D is now a free flyer."
If the deployment is successful, NanoSail-D will stay in low-Earth orbit between 70 and 120 days, depending on atmospheric conditions. NanoSail-D is designed to demonstrate deployment of a compact solar sail boom system that could lead to further development of this alternative solar sail propulsion technology and FASTSAT’s ability to eject a nano-satellite from a micro-satellite -- while avoiding re-contact with the FASTSAT satellite bus.

Nanosail D2 packets were received and decoded by PA3GUO , unfortunately the last decoded packet was one minute before deploy time. Spacecraft is alive and healthy.
Waiting for next contact, deployment status will be known at that time.
I didn't have time to set up to decode packets earlier tonight, will try to get my setup working for tomorrow's pass over me. (no association with mission other than a listener)

An operator in Inuvik, NT Canada just decoded a packet that seems to indicate that the sail has deployed. Waiting for official confirmation.
If so, what a great day- The first Nanosail went down with a Falcon 1, this one was thought stuck in its host.
And now it worked.

Can the open Nano Sail D be seen with a telescope or binoculars?
p.s. Good news. Well done.

NanoSail D predictions are up on Heavens Above. The brightness predicted seems to vary between about magnitude 2 and magnitude 4 depending on the pass.
