Impending Missile Launch from Kotelnyy Island?

Gunnery/missile area closure near Kotelnyy Island - September 15-21, 2014 (Map courtesy of Google Earth)

An interesting area closure has been declared west of Kotelnyy Island, where a Russian Navy Northern Fleet task group arrived this past weekend:

The area closure went into effect on September 15 and will expire on September 21. The warning messages indicated missiles would be launched during the closure times. Given that the closure touches the coastline, it is reasonable to believe a land-based coastal defense cruise missile (CDCM) will be fired. The Northern Fleet task group is comprised of six ships, only one of which is armed with any type of missile: Udaloy I-class destroyer "Admiral Levchenko" with its SA-N-9 Gauntlet AAW and SS-N-14 Silex ASW missile systems. It's highly unlikely the area closure was declared solely for these systems.

A late August Russian MOD press release reported that "coastal missile...units" were part of the "Admiral Levchenko" task group, but it didn't state whether the task group's two landing ships were ferrying the mobile CDCMs or if they were being ferried to the island by other means. At least five commercial vessels have made or soon will make trips to Kotelnyy Island this summer: "Aleksandr Suvorov", "Arkadiy Chernyshev", "Kapitan Borodkin", "Valeriy Vasilyev", and "Yuriy Arshenevskiy". The latter unit ferried unspecified military hardware to the island earlier this month.

At its farthest points (from Mys Durnoy (Zarya Strait) in the south to the northernmost coordinate), the area closure is just over 83nm in length. While it is unknown exactly which mobile CDCM systems may have been ferried to Kotelnyy Island, the length of this area closure could support launches by either the SSC-1B Sepal (approx. range 250nm) or SSC-3 Styx (approx. range 45nm). Given the Russians may place a target near the middle of the area or even closer to shore, it seems like a waste to launch the longer-range SSC-1B only 40 or so nautical miles. That distance, however, would be perfect for the near maximum range of the SSC-3.

A missile shot from the island will certainly be covered by both military and commercial media sources, at which we point we should be able to solve this riddle.
