he HF Active Auroral Research Program (HAARP) in Alaska and the Long Wavelength Array (LWA) in New Mexico are planning an additional lunar echo experiment for January 18-19. Interested radio amateurs are invited to participate in this experiment by listening for the lunar echoes and submitting reports. On January 19, listen on 6.7925 MHz from 0500-0600z, and on 7.4075 MHz from 0600-0700z. On January 20, listen on 6.7925 MHz from 0630-0730z and on 7.4075 MHz from 0730-0830z (depending on frequency occupancy at the time of operation, it may be necessary to adjust the frequency slightly). Based on previous experiments, investigators believe it should be possible to hear the lunar echoes with a standard communications receiver and a simple 40 meter dipole antenna. The format for the transmissions will follow a five second cycle beginning on the hour and repeating continuously. The HAARP transmitter will transmit for the first two seconds. The next three seconds will be quiet to listen for the lunar echo. Then HAARP will transmit again for two seconds, repeating the cycle for one hour. In the second hour, this five second repetitive cycle will be repeated at a different frequency. All transmissions from HAARP will be CW (no modulation). Depending on ionospheric conditions, it may or may not be possible to hear the HAARP transmission directly via skywave propagation. Since HAARP will not be using any modulation, set your receiver on to CW mode to hear HAARP and the lunar echo. Investigators are interested in receiving signal reports from radio amateurs who may be able to detect -- or not detect-- the lunar echo or the transmitted skywave pulse from HAARP. Submit reports via e-mail to mbreport@haarp.alaska.edu and list your call sign and the type and location of your receiving equipment and antennas.

Scientists Feel Miscast in Film on Life’s Origin |

A few months ago, the evolutionary biologist Richard Dawkins received an e-mail message from a producer at Rampant Films inviting him to be interviewed for a documentary called “Crossroads.” The film, with Ben Stein, the actor, economist and freelance columnist, as its host, is described on Rampant’s Web site as an examination of the intersection of science and religion. Dr. Dawkins was an obvious choice. An eminent scientist who teaches at Oxford University in England, he is also an outspoken atheist who has repeatedly likened religious faith to a mental defect. But now, Dr. Dawkins and other scientists who agreed to be interviewed say they are surprised — and in some cases, angered — to find themselves not in “Crossroads” but in a film with a new name and one that makes the case for intelligent design, an ideological cousin of creationism. The film, “Expelled: No Intelligence Allowed,” also has a different producer, Premise Media. The film is described in its online trailer as “a startling revelation that freedom of thought and freedom of inquiry have been expelled from publicly-funded high schools, universities and research institutions.” According to its Web site, the film asserts that people in academia who see evidence of a supernatural intelligence in biological processes have unfairly lost their jobs, been denied tenure or suffered other penalties as part of a scientific conspiracy to keep God out of the nation’s laboratories and classrooms. Mr. Stein appears in the film’s trailer, backed by the rock anthem “Bad to the Bone,” declaring that he wants to unmask “people out there who want to keep science in a little box where it can’t possibly touch God.” If he had known the film’s premise, Dr. Dawkins said in an e-mail message, he would never have appeared in it. “At no time was I given the slightest clue that these people were a creationist front,” he said.

Sunspot is Harbinger of New Solar Cycle, Increasing Risk for Electrical Systems |

A new 11-year cycle of heightened solar activity, bringing with it increased risks for power grids, critical military, civilian and airline communications, GPS signals and even cell phones and ATM transactions, showed signs it was on its way late yesterday when the cycle’s first sunspot appeared in the sun’s Northern Hemisphere, NOAA scientists said. “This sunspot is like the first robin of spring,” said solar physicist Douglas Biesecker of NOAA’s Space Weather Prediction Center. “In this case, it’s an early omen of solar storms that will gradually increase over the next few years.” A sunspot is an area of highly organized magnetic activity on the surface of the sun. The new 11-year cycle, called Solar Cycle 24, is expected to build gradually, with the number of sunspots and solar storms reaching a maximum by 2011 or 2012, though devastating storms can occur at any time. During a solar storm, highly charged material ejected from the sun may head toward Earth, where it can bring down power grids, disrupt critical communications, and threaten astronauts with harmful radiation. Storms can also knock out commercial communications satellites and swamp Global Positioning System signals. Routine activities such as talking on a cell phone or getting money from an ATM machine could suddenly halt over a large part of the globe.

Based on the climate data from 1970-2000, this graphic from the National Climatic Data Center shows the odds of having a "White Christmas" (they define it as having at least 1 inch of snow on the ground). For most of the Tennessee Valley, the probability is less than 5%, though it jumps to 5-10% in parts of Franklin and Lincoln Counties in Tennessee. Click the graphic to enlarge.
hmm 5 to 10%... Dreaming of a White Christmas? |

Nitrogen Triiodide Detonation |

A ring stand is set up with two rings, each holding a filter paper spread with nitrogen triiodide. The bottom filter paper is touched with a feather, causing an explosion that detonates the other sample of nitrogen triiodide. Close up views and slow motion of this very dangerous reaction are shown.
I older friend of mine said they would paint this on windows and let a fly loose and watch the windows break... And sandwich it in between duct tape and let it dry and run it over with a car or stick it in door jam... hehe *evil grin* Nitrogen Triiodide Detonation |
