At 2 a.m. EDT on August 25, Vamco was still enroute to the Alaskan islands headed north-northeast at 38 mph in the north Central Pacific Ocean. He was about 980 miles west-southwest of Kiska, Alaska. That's near 41.6 north and 158.9 east. Vamco will continue moving northeast toward the far southwestern Aleutian Islands.
NASA's QuikScat satellite was able to peer through Vamco's clouds on August 24 using microwave technology and actually measure the winds on the surface of the ocean beneath him. QuikScat found Vamco still had sustained winds near 65 knots (74 mph), so he was still at a category one hurricane strength at that time.
Meanwhile, in the early morning hours of August 25, visible satellite imagery from NASA's Terra satellite and the Moderate Imaging Spectroradiometer (MODIS) instrument revealed Vamco's clouds still had a good circulation.
Vamco is starting to weaken, however. Infrared satellite imagery, such as that from NASA's Aqua satellite's Atmospheric Infrared Sounder (AIRS) instrument, indicated that Vamco's eye has become elongated and grown larger. Also, Vamco's convection and rainfall has started to erode as wind shear has increased. Vamco is expected to continue weakening as winds continue to batter his circulation.
Although the U.S. Navy's Joint Typhoon Warning Center has issued their final advisory on Vamco, shipping interests in the North Pacific Ocean should be aware of high seas.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
