By some good fortune you've managed to navigate to Tom Madigan's home page at Stony Brook's MARIACHI project. MARIACHI is an acronym for "Mixed Apparatus for Radar Investigations of Atmospheric Cosmic Rays of High Ionization".

I'm a life long amateur astronomer, a former staff member of the Vanderbilt Planetarium in Centerport, an adjunct professor of Astronomy and Physics at Queensborough Community College, Long Island University and a member of the adjunct faculty at Suffolk County Community College's Physical Sciences Department, a life-time member of Custer Institute, Southold, the editor and producer of Custer Institute's monthly journal, the Custer Comment, a fellow of the Royal Astronomical Society, the same society that had Sir Isaac Newton and William Herschel as Fellows and an associate member of the American Astronomical Society. Additionally, I'm on the advisory board of the Montauk Observatory and a member of the Stony Brook Alumni Association.

In addition to being involved with this fantastic project here at Stony Brook, I'm working on the Space Weather Project at Suffolk County Community College. This project is being sponsored by Stanford University with sites located at colleges and universities worldwide. To access SCCC's daily contribution to the worldwide solar-weather data, please navigate to http://sid.stanford.edu/database-browser/index.jsp?monitor=S-0054-FB-0054&submit=Show+Data&date=2007-06-01T00.00.00 . The image displayed on this page is for 1 June 2007 and shows 2 confirmed solar events occuring on that date. There are many image formats and combinations available at the Stanford site: http://sid.stanford.edu/database-browser. The antenna at SCCC is a 2 meter VLF antenna that monitors transmissions at 24 Khz from the US Naval Communications center at Cutler, ME, and is in continuous operation.

Frequent TOI:

• The SID Program is sponsored by the Solar Center at Stanford University (http://solar-center.stanford.edu)
• - if you're interested in participating, please send me an email at madigat@sunysuffolk.edu;
• SID is an acronym for Sudden Ionispheric Disturbance;
• Sunrise and sunset events have clear signatures (why?);
• There is a probably that a significant relationship exists between SID phenomenon and Cosmic Ray events;
• Radio frequencies of very long wavelength (very low frequency or "VLF") "bounce" back off the ionosphere thus, conveniently for us, allowing radio communication "over the horizon" and around our curved Earth. The ionosphere reacts strongly to the intense x-ray and ultraviolet radiation released by the Sun during a solar flare, solar storm, or coronal mass ejection. By monitoring the signal strength from distant VLF transmitters and noting unusual changes as the waves bounce off the ionosphere, we can monitor and track these disturbances;

MARIACHI 2008 (7th July - 11th July, 2008)

Monday, 7th July 2008 - The workshop begins in earnest

• Continental Breakfast
• Intro by Helio

Constructed a variable frequency, flashing LED circuit. When completed, the frequency was set to 30 Hz followed by time-lapse images taken by Helio of the assembled device falling from a height of 2 meters.
