Special Containment Procedures: SCP-XXXX is considered neutralized at the time of writing. In the event that SCP-XXXX manifests, an R.W.D.1 is to be deployed to divert the signals to Lunar Area-32. If SCP-XXXX-1 arrives at earth and proves to be a threat a full planetary evacuation is to commence, with all resources being dedicated to the neutralisation of SCP-XXXX-1. Site administrator Adams is to remain under heavy surveillance until his involvement with the Sarkics █████ and ████████ is fully understood.

Description: SCP-XXXX refers to a series of radio transmissions received over 13 years (1988-2000) which originated from the Canis Major Overdensity. SCP-XXXX is able to be understood by any individual of any nationality, with the transmission being interpreted in the listener's native tongue. SCP-XXXX instantaneously manifested within multiple planetary systems, each instance travelling 20000 lightyears over the course of 10 hours before demanifesting. This pattern continued on a yearly basis for a further 12 years before ceasing permanently. Additionally, SCP-XXXX displayed the remarkable ability to pass through all materials, passing through every planet within the solar system, and immediately being picked up by multiple foundation sites. SCP-XXXX can have its path diverted with the use of an R.W.D.

1988 transmission (declassified):

Your protection is no longer possible. We are sorry.

Following the first SCP-XXXX transmission a series of cover-up stories were released, claiming the transmission to be a worldwide hoax made by various hackers of a fake group named "Beau Leaf". A series of systems were set up to detect SCP-XXXX before it could reach earth and have its path diverted.

SCP-XXXX-1 is the designation for a large tumorous mass currently 10000 lightyears from earth. SCP-XXXX-1 was observed exiting the Canis Major Overdensity on ███ ████ and has maintained a direct trajectory towards earth. SCP-XXXX-1 travels at an approximate speed of 5000000000km/h, and is likely to reach our planetary system within 2160 years.

Addendum XXXX-A: A foundation probe has brought significant attention to the Canis Major Overdensity, having been destroyed moments after entering the galaxy. Five minutes before entering the following transmission was received:

Galactic quarantine in effect. Turn back. Turn back. Turn back.
