Item #: SCP-1149
Object Class: Euclid
Special Containment Procedures: SCP-1149 is to be kept in a secure room at the west-most end of Site 37, located in a remote location on the northwest coast in the United States. SCP-1149 is to be guarded by one armed guard. To mitigate the damage caused by its effects, SCP-1149 is to be pointed due west toward the Pacific Ocean at all times. It is to be firmly attached to its support structure, which is itself to be anchored to the floor. One closed circuit camera is to be kept focused on SCP-1149, and accelerometric and atmospheric sensors attached to the support structure will transmit readings to a nearby monitoring center.
Atmospheric conditions within SCP-1149's containment room are to be kept stable with an air lock permitting entry. A single fan mounted in the wall of the room to the east of SCP-1149 is to be tightly covered and locked in position until it is required for testing. When opened, air speed shall not exceed 30 kph (19 mph). Access is restricted to Level 1 personnel with the approval of a superior. All test software and all test equipment must be inspected by at least two Site 37 Technical Review staff members. SCP-1149's wires must be grounded during any test until more information about the object is obtained.
SCP-1149's rough "cone of effect" has been classified as a conservation area and all non-emergency watercraft and aircraft are disallowed access. Two patrol vessels, using United States Coast Guard motor lifeboats will monitor the boundaries of the cone of effect for trespassers. Patrols should not pursue trespassers, but should contact researchers in charge of SCP-1149 for further instructions.
Description: SCP-1149 is a rusted weather vane approximately 45 cm (18 in) long and 30 cm (12 in) tall bearing no discernible manufacturer's mark or any particularly identifying features aside from the common rooster ornamentation. The base of the vane is corroded and appears to have broken off from its mount sometime prior to recovery.
Within the severed mount point, two frayed wires run further up into the vane. Interior imaging shows them terminating just beyond the "feet" of the rooster. The wires are believed to have once connected to some sort of control mechanism. Analysis has shown that no power source exists within SCP-1149 and interior imaging has discovered nothing else of note.
SCP-1149's anomalous properties appear to always be in effect but are amplified in density and frequency when wind passes over it in the direction in which it is pointing. While active, weather activity will become erratic in the vicinity of SCP-1149. Most of the anomalous effects will occur within a "cone of effect" in the direction that the arrow on the weather vane is facing. The cone has a rough length of approximately 215 km (135 mi) and an arc of 5 degrees. While the frequency of appearance of these effects does taper sharply near the boundaries of this cone, anomalous effects have been observed, on rare occasions, well outside of the cone of effect.
When kept out of the wind, SCP-1149 causes an anomalous weather effect to occur within its cone of influence once every 15 minutes on average, with each event typically lasting between 10 seconds and 2 minutes, depending on the intensity of the event. When exposed to air traveling along it's length (i.e. west, in it's current orientation), the events become more frequent and last longer. When exposed to winds between 25 and 40 kph (16 and 25 mph), the events will be continuous at the center of the cone of effect, with events stopping and starting randomly near and beyond the borders. Beyond 40 kph, events will begin to overlap, creating a continuous event growing in intensity until the speed of the wind passing over SCP-1149 decreases below this threshold.
Addendum 1149-1: SCP-1149 was discovered in the ruins of a small coastal cottage in ██████████, ██ after a strong storm had passed through the area. While the primary storm itself was not strange in and of itself, SCP agents were dispatched to the area when highly anomalous weather effects were observed over the Pacific Ocean, focused in a rough cone-shape emanating from ██████████. Agents were unable to find the owner(s) of the cottage, though evidence suggests that the property had been inhabited until a short time before the cottage's destruction. SCP-1149 was found firmly affixed to the remains of what is assumed to be the interior wall of a shed. A wider search of area was unable to locate SCP-1149's base or any further information regarding SCP-1149's origin or operation.
Addendum 1149-2: Wind Testing Log All tests were conducted under closed conditions at Site 37. Weather stations took readings from Site 37 itself, as well as from observation vessels located at multiple points along the boundaries of SCP-1149's cone of influence. When high-accuracy readings were required, a geostationary satellite was used. The wires leading into SCP-1149's base were grounded for these tests.
Addendum 1149-3: Electrical Testing Log All tests were conducted under closed conditions at Site 37. Weather stations took readings from Site 37 itself, as well as from vessels located at multiple points along the boundaries of SCP-1149's cone of influence. When high-accuracy readings were required, a geostationary satellite was used. SCP-1149 was under 5 kph wind speeds for each of these tests. The wires leading into SCP-1149's base were connected to varying electrical signals.
