Cygnuss remains in a 413.6 km Perigee, 422.5 km Apogee orbit about 5 km above the ISS. (Perigee: 408.8 km, Apogee: 417.3 km)
What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

Cygnus has circularized its orbit at 417.7 km.  (Perigee: 417.7 km  Apogee: 417.7 km) 
This remains 5.0 km higher than the ISS. (Perigee: 408.8 km  Apogee: 417.2 km ).

Cygnus is now reported by N2YO to be way above the ISS
Perigee: 502.6 km 
Apogee: 511.2 km
Is this real?
If so, what's going on?

Jonathan's Space Report reports that the second pair of Spire Lemur-2 nanosats have been released from Cygnus. 
He does not yet have catalog numbers.

Do we know an actual time for the destructive re-entry on Sunday?

Ultimately, the whole spaceship and its contents will burn up on re-entry to Earth's atmosphere at 6:30 pm (2330 GMT) Sunday, November 27.

"Cygnus reentry is scheduled for 6:36PM ET tonight. The first orbit lowering burn was successfully completed earlier this afternoon."

"Cygnus reentry burn is complete & looks nominal. Currently crossing 460km altitude and falling."

Orbital ATK Ends 2016 with Three Successful Cargo Resupply Missions to the International Space Station


Cygnus Continues Its Use as a Platform for Performing Experiments in Space

OA-5 Mission Marked Antares Return to Flight Operations from NASA’s Wallops Flight Facility

Dulles, Virginia 28 November 2016 – Orbital ATK (NYSE: OA), a global leader in aerospace and defense technologies, announced it successfully completed its sixth cargo delivery mission to the International Space Station for NASA. Known as OA-5, the mission marked the company’s return to flight operations from NASA’s Wallops Flight Facility in Wallops Island, Virginia and the second time Cygnus™ has been used as a platform for conducting research in space.

“The OA-5 mission was filled with numerous accomplishments,” said Frank Culbertson, President of Orbital ATK’s Space Systems Group. “We returned to flight operations at our home base in eastern Virginia, successfully launched aboard our upgraded Antares rocket and once again showcased Cygnus’ dynamic versatility and value to serve as a platform for conducting science experiments and payload operations for key customers. I congratulate the entire NASA and Orbital ATK teams for a job well done.”

On November 27 at approximately 6:40 p.m. EST, Cygnus performed a safe, destructive reentry into Earth’s atmosphere over the Pacific Ocean east of New Zealand, successfully concluding the OA-5 mission.

Named the “S.S. Alan Poindexter” in honor of the two-time Space Shuttle veteran, Cygnus launched on October 17, and six days later, berthed with the International Space Station, delivering approximately 5,300 pounds (2,400 kilograms) of vital supplies and science experiments to the astronauts on board. It remained docked for 29 days and departed the space station on November 21. Prior to its departure, the astronauts loaded the cargo module with approximately 2,469 pounds (1,120 kilograms) of items for disposal.

After departing the space station, Cygnus moved into its next phase of serving as an in-orbit science platform. It successfully executed the Saffire-II payload experiment and deployed four CubeSats that will be used for meteorological research. The mission marked the first time that a cargo spacecraft deployed satellites above the orbit of the International Space Station.

The Spacecraft Fire Experiment-II (Saffire-II) was the second in a series of tests to study the behavior of large-scale fires in microgravity. Results from Saffire experiments lead to technologies and materials that will make deep space exploration spacecraft safer for astronauts; a critical factor as NASA prepares for long-duration missions on its journey to Mars.

Orbital ATK successfully sent the command from the ground to initiate the Saffire-II experiment. The command intentionally ignited nine different experimental material samples inside the Cygnus pressurized cargo module which grew and eventually burned out. The experiment, designed by NASA’s Glenn Research Center and funded by NASA’s Advanced Exploration Systems Division, executed as intended. NASA’s Glenn Research Center is currently evaluating all data and imagery gathered from the test.

Following the Saffire-II experiment, Cygnus used a NanoRacks CubeSat deployer to launch four CubeSats into orbit. The spacecraft boosted its altitude to a record 500 kilometers before releasing the satellites into orbit. The altitude boost will increase the on-orbit lifespan of the satellites from about nine months in a typical International Space Station deployment to at least two years. Now in their intended positions, the satellites will help enhance weather forecasting capabilities.

Preparations are underway for the company’s next mission under NASA’s Commercial Resupply Services-1 (CRS-1) contract. OA-7 is targeted to launch in the spring of 2017. Under the CRS-1 contract with NASA, Orbital ATK will deliver approximately 66,000 pounds (30,000 kilograms) of cargo to the International Space Station through 2018. Beginning in 2019, Orbital ATK will carry out a minimum of six initial cargo missions under NASA’s CRS-2 contract.

Tried publishing this last night, but it had a cache error (since fixed), which wouldn't allow me to publish with confidence, so this is the article by Chris Gebhardt, updated to EOM

The Heavens Above satellite database now lists all four of the new Spire Lemur-2 nanosats that were released from the OA-5 Cygnus. 

Date UT          Name                             Launch Vehicle  Site     Mission     INTL.   Catalog
Nov 25 2015  Lemur-2- Xiaoqing           Cygnus OA-5, LEO   Weather/AIS   62C    41871 
                     Lemur-2- Sokolsky                                        Weather/AIS   62D   41872
Nov 26 0010   Lemur-2-Anubhavthakur  Cygnus OA-5, LEO   Weather/AIS   62E    41873
                      Lemur-2-Wingo                                            Weather/AIS   62F    48174

All are in 498 x 507 km 51.6° inclination orbits.  It will be interesting to watch their decay over the coming years.

Orbital ATK

Published on Dec 16, 2016
Our OA-5 mission successfully launched aboard our Antares rocket from Wallops Flight Facility, Virginia, on October 17, 2016. Out Cygnus spacecraft carried approximately 2,400 kg (5,290 lbs.) of supplies and science experiments for the International Space Station (ISS). The mission was successfully completed on November 27, 2016. Get more information on the mission here: ow.ly/BFEB307bUnZ
