Solar Max

Solar Maximum Is a term the Doomsday crowd is banding about as the next cause of our extinction. While the end of the world has been predicted at least 242 times. End of the world predictions have a consistent track record, as of my current knowledge the world has not ended yet.  I predict that the trend will continue.

But will Solar Max do anything? The answer is yes, it will have a real and measurable impact on the world. Billions of dollars of damage to infrastructure has been incurred during the last Solar Max in 2000

Living with a star has it'd hazards. There is Space Weather due to the nature of how the Sun produces light. For the protection of electronics and communication systems, it can be thought of as a Solar lightning storm. It's a much more regular event than you would expect. At the scale of the solar system, such particle emissions are directional and effect the other planets as well.  This current Cycle 24  is expected to be a large one, second only to the current historical record set In 1954. The impact to radio communications is significant and has been a issue of concern to Amateur radio operators for some time.

Preparations
The same steps for protecting the electrical and communication infrastructure that is performed for protection from Lightning storms and other atmospheric storm is perscribed for this.  This is a excellent opportunity to review the existing protections in place, and maintain or replace aged components and protection systems. As ligning arresters, surge supressors and other protection devices, provide protection they deterioate and lose capactity to protect the systems. How often should a protection device be replaced, Depends largely on the amount of surges it has handled, and its age. This is a good opportunity to inspect and install protection in places where it may not have been made.

- Electrical Grounding for Equipment in the office, home and data center, the office an home should be inspected and repaired as necessary, this is a important factor for proper system operations for many computers

- Lightning arresters, surge supressors and other protections should be placed in circuits that penetrate exterior walls. It is also time to inspect and replace older protection units also.
   - Power
   - Cable TV
   - Phone
   - Antenna
   - Internet
   - and other signal lines.

As a rule of thumb, if it can carry electricity it can carry lightning.

As lightning and the impact of solar storms can penetrate through most building materials, the surge suppressors that are used in data centers should be reviewed for age and condition. Smaller desktop units should be replaced and maintained if they are more than 3 years old.

A Further step that can help eliminate the impact of some of the EMI and RFI is twisting a cable bundle, like twisted pair cable is. the exposes different sides of the wires to the Electromagnetic filed, and will cancel or reduce the induced voltages and help minimize the impact of whatever energey that might be induced.
