Science Students See Their Face In Space:

May 24, 2013 07:33 AM - eHam.net News -- Students from Ralph McCall School and members of the Airdrie Space Science Club (ASSC) weren't the only ones excited to get the third flight of the Airdrie Balloon Experiment off the ground, May 18. Their Grade 6 science teacher, Brian Jackson, a self-professed "card-carrying space geek," could hardly contain his excitement as he prepared for the launch of the ABE 3 air balloon at the Beiseker Airport just after 8 a.m. With help from three volunteer Amateur Radio Operators (ARO), 10 students and a dozen parents, Jackson sent the five-foot helium-filled balloon towards space. A small homemade pay load was attached to the bottom and packed with a peanut butter sandwich, a Lego man and temperature sensors. Pictures of the Grade 6 science class and members of the Airdrie Space Science Club were attached to the edge. A video camera was installed inside the payload to record what happens to the contents when the balloon is in motion and to capture the kids' faces with space in the background.

Amateur Radio Operators Helping with Oklahoma Relief:

May 24, 2013 07:33 AM - eHam.net News -- Amateur Radio Operator Ken Malgren with the Disaster Relief Network knows how quickly a storm can hit. He is a retired firefighter turned Ham Radio operator who monitored Monday's twister as it rolled though Oklahoma City. "I was prepared to respond that day if I needed to," he said. The EF-5 tornado took lives, homes and left behind rubble. It also took out communication for people in the area. Experts say during natural disasters, cell phones have a tendency to go down either from damage to towers or overload of the system. "When you try to jam all the people that are trying to make phone calls into a limited infrastructure, the system gets overloaded very quickly," Malgren said.

'Dynamo' Accounts for Sun's Weather Cycle:

May 24, 2013 07:33 AM - eHam.net News -- U. LEEDS (UK) / U. CHICAGO (US) -- Researchers have discovered what drives the generation of astrophysical magnetic fields like the Sun's. Scientists have known since the 18th century that the Sun regularly oscillates between periods of high and low solar activity in an 11-year cycle, but have been unable to fully explain how this cycle is generated. It has become increasingly important to be able to understand the Sun's magnetic activity, as it is the changes in its magnetic field that are responsible for "space weather" phenomena, including solar flares and coronal mass ejections. When this weather heads in the direction of Earth it can damage satellites, endanger astronauts on the International Space Station, and cause power grid outages on the ground. The research, published in Nature, explains how the cyclical nature of these large-scale magnetic fields emerges, providing a solution to the mathematical equations governing fluids and electromagnetism for a large astrophysical body. The mechanism, known as a dynamo, builds on a solution to a reduced set of equations first proposed in the 1950s which could explain the regular oscillation but which appeared to break down when applied to objects with high electrical conductivity. The mechanism takes into account the "shear" effect of mass movement of the ionised gas, known as plasma, which makes up the Sun. More importantly it does so in the extreme parameter regime that is relevant to astrophysical bodies.

Solar Activity on the Rise:

May 20, 2013 07:33 AM - eHam.net News -- Faraway as it is, anyone could mistake the Sun for a smooth, uniform, boring ball of gas but the reality could not be more different. Earlier this week, in the space of two days, the Sun emitted four massive blasts of radiation with Tuesday's solar flare being the strongest of the year so far. The Sun's activity changes in intensity periodically, with its main cycle taking an average of eleven years to complete. The present cycle, cycle 24, started in 2008 and is expected to peak later this year. This increase in solar activity leads to an increase in a number of a variety of solar phenomena, such as sunspots, solar flares and coronal mass ejections (CMEs). Solar flares are extremely strong bursts of energy that occur when energy stored in the magnetic fields of the Sun's atmosphere is suddenly released. A related phenomenon, coronal mass ejections are massive eruptions in the solar atmosphere that release millions of tonnes of solar material into space. Flares can fall into one of five categories: A, B, C, M, or X, each category ten times stronger than the one before, with X-class flares being the strongest. Additionally, each category, except X-class, is further divided into nine subcategories, from 1 to 9. The most intense flare ever recorded went as high as X28. This week's flares ranged in intensity from X1 to X3.2.
