NASA reported on Wednesday that Orbital Sciences Corp., a commercial spaceflight company on a cargo delivery mission to the International Space Station, had called off its rocket launch that day from the agency's Wallops Flight Facility in Virginia because of the unusually high levels of radiation.
"This was a huge event, with the CME now classified as an R-type for its rarity, with an estimated speed much higher than we have recently seen because of the massive release of energy," commented Andrew Gerrard, an NJIT professor of physics and deputy director of the university's Center for Solar-Terrestrial Research.
"Eruptions of this magnitude can cause circulation changes in the upper atmosphere, communications disruptions in space and on the ground, and other potential electrical anomalies. We can lose track of space craft, whose orbits can be disrupted by these in these events. It's like driving through molasses."
NJIT is continuing to measure the solar explosion's impact from space with its instruments on the Van Allen Probes, NASA space craft that travel through the inner magnetosphere, and on the ground through instruments like those in the NATION Fabry-Perot systems in North America, which measure thermospheric winds and temperatures, and in systems across the Antarctic plateau that measure geomagnetic variability.
"This is a beautiful opportunity to look at how this material from the sun is injected into the radiation belts, inner magnetosphere, and upper atmosphere," Gerrard said. "We may not see anything like this for another decade."
NJIT's Center for Solar-Terrestrial Research also operates the university's Big Bear Solar Observatory (BBSO) in California, which is home to the world's most powerful ground-based telescope dedicated to solar research. NJIT professors at BBSO in Big Bear have obtained new and remarkably detailed photos of the Sun with the New Solar Telescope (NST).
The flare, a giant burst of radiation designated as X-class for the most intense flares, is centered over a giant sunspot AR1944 located at the center of the sun. By Wednesday, the solar radiation storm had intensified to an S3 or strong event, while the coronal mass ejection was forecast to set off G3 (Strong) Geomagnetic Storm activity through January 9 and 10, NASA said.
Solar flares and coronal mass ejections regularly send bursts of charged particles and high energy radiation in Earth's direction at nearly the speed of light. Upon reaching our atmosphere within minutes, solar radiation can destroy the electronic systems in satellites used in telecommunications, weather forecasting and GPS systems, among other services, as well as devices on the ground, such as transformers.
In 1989, for example, a solar storm brought down the Hydro-Quebec grid within minutes, blacking out the entire province as well as parts of the Northern United States for several hours.

NJIT, New Jersey's science and technology university, enrolls 10,000 students pursuing bachelor's, master's and doctoral degrees in 120 programs.
The university consists of six colleges: Newark College of Engineering, College of Architecture and Design, College of Science and Liberal Arts, School of Management, College of Computing Sciences and Albert Dorman Honors College. U.S. News & World Report's 2011 Annual Guide to America's Best Colleges ranked NJIT in the top tier of national research universities. NJIT is internationally recognized for being at the edge in knowledge in architecture, applied mathematics, wireless communications and networking, solar physics, advanced engineered particulate materials, nanotechnology, neural engineering and e-learning.
Many courses and certificate programs, as well as graduate degrees, are available online through the Division of Continuing Professional Education.

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.
“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...
With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.
Elpasolite is a glassy, transparent, shiny and soft mineral with a cubic crystal structure. First discovered in El Paso County (Colorado, USA), it can also be...
For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.
K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
