Description: SCP-1214-JP is a common incandescent light bulb located at approximately 5,000 meters above the ground, suspended from an undetermined altitude. The light output is about 1,600lm (equivalent to 100W). A metal string of about 30cm is attached; the light can be turned off by pulling this.
SCP-1214-JP appears in the sky above a certain an unspecified urban area at night with its light on, and disappears at dawn. Other behaviors have not been observed.
Anomalous properties of SCP-1214-JP manifest when a human reaches its location and turns off its light manually. At the moment of lights-out, the urban area under SCP-1214-JP will vanish and be erased from all records and memories. History will be altered in a way that the city never developed, leaving behind a wilderness without any man-made structures. Since this process involves a large-scale retroactive alteration of history, experimentation has been strictly forbidden.
According to the study of the retroactive alteration traces that led to its discovery, SCP-1214-JP was turned off one time in December 2008, outside of experiments. The person who turned off its light has not been identified, and is believed to have vanished as a result of history alteration.
Addendum: On December 14, 2018, at approximately 8:00 p.m., SCP-1214-JP appeared in the sky above an uninhabited area in the mountains of ████ Prefecture with its lights off. The metal string normally attached to it was not seen. SCP-1214-JP remained motionless, and disappeared after the Geminid meteor shower maximum activity that occurred on the same day. No similar event has been observed since then.
