3/16/2011 EDIT: The Wing Kp Predicted Geomagnetic Activity Index model is now deployed and operational. Costello is now considered non-operational and will be discontinued on 23 Mar 2011. Comments and questions are welcomed at SWPC.CustomerSupport@noaa.gov
The Wing Kp Predicted Geomagnetic Activity Index model is known to perform well for large geomagnetic storms and includes both a 1 hour and a 4 hour advance prediction of activity. Wing Kp 7-day model output is available in ascii data list format at http://www.swpc.noaa.gov/wingkp/wingkp_list.txt and via Anonymous FTP at ftp://ftp.swpc.noaa.gov/pub/lists/wingkp
Build a visual indicator of the Northern Lights using the Arduino. Know when to go outside and look up, no matter where you live!
For years I have struggled to find a good way of alerting me to Northern Lights activity. I have tried email alerts and real-time monitoring software. Nothing worked well and I would regularly miss good displays.
Enter the Costello Geomagnetic Activity Index. Simply put, this is a prediction of auroral activity. It is pretty reliable and gives about an hour's notice of northern lights activity. The problem is, of course, you have to keep checking the web page to catch any jump in the Index.
What we will build is a visual representation (an LED display) of the current level of auroral activity. The build consists of three main parts: a PHP Web scraping script, a Processing script, and an Arduino script. The LED lights green for low activity, blue for moderate, red for high activity and white for GET OUTSIDE NOW! I have mounted this in an old clock face so it is always visible in my living room. Essentially this is a poor man's Ambient Orb costing under $40 to build compared to the Ambient Orb's $150 + S/H + $6.95/mo for custom monitoring.
Right off the bat I wish to thank Tod E. Kurt for his Spooky Arduino projects and his help getting me through my own stupidity. It is his scripts this project is based on and I strongly recommend checking out his blog for great Arduino projects.
