At 1500 UTC (10 a.m. ET) on November 17, Anja's maximum sustained winds were sustained at 75 knots (86 mph). Anja's center was located 715 miles east-northeast of La Reunion Island, near 18.3 South and 66.5 East. Anja is moving south-southwest at 12 mph. The storm seems to be spreading out as its weakening, as tropical storm force winds now extend out to 115 miles from the center (earlier today, they only extended 75 miles out from the center).
When tropical cyclone Anja formed on November 14, it was the first tropical cyclone in the southwestern Indian Ocean. That signaled the tapering off of northern hemisphere tropical cyclone activity and the start of tropical cyclone formation in the southern hemisphere. The Atlantic Ocean hurricane season officially ends at the end of November while the southwest Indian Ocean tropical cyclone season starts on November 1 and ends on April 30.
When the Tropical Rainfall Measuring Mission (TRMM) satellite passed over Anja on November 15 at 0904 UTC it had a well-defined eye and was increasing in strength from a category 2 tropical cyclone (on the Saffir-Simpson scale) to a powerful category 3 tropical cyclone later that day. TRMM is a joint mission between NASA and the Japanese space agency JAXA.
The TRMM satellite passed over Anja again on November 17 at 0850 UTC. The data from TRMM made it clear that upper level wind shear (winds blowing at different directions in the atmosphere that can tear a storm apart) had caused Anja to weaken greatly from its earlier maximum category 4 intensity. Anja no longer had a well defined eye but the TRMM derived rainfall analysis showed there was still very heavy rainfall in an area near Anja's center.
Anja is predicted to continue weakening and move harmlessly toward the southeast over the open waters of the south Indian Ocean.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
