Between 9 and 10 AM on Wedneday, April 11, a severe geomagnetic storm struck earth. Auroras may be visible into the middle lattitudes tonight, which would include most if not all of the United States.

A G-4 level magnetic storm is the second highest on the scale. It is capable of causing widespread voltage control problems in power systems, and inducing protective devices to remove power assets from the grid.

Satellites may have tracking problems, and surface charging could lead to damage in some cases.

Radio signal propagation may be sporadically disrupted, satellite navigation degraded, and low-frequency radio navigation also disrupted.

Radon is produced by the decay of uranium, which is contained in the building blocks that were used to build some of the pyramids and other monuments. High levels of radon increase the risk of lung cancer.

Guides currently work inside these monuments for 4 hours a day. If their working hours were doubled, their radon exposure would exceed the international safety limit. Visitors are not at risk, since their exposure time is so limited.

They will be using sophisticated equipment to investigate areas such as the dungeons of Edinburgh Castle and the vaults underneath South Bridge. Edinburg was chosen because of its high concentration of paranormal sightings.
