The Atmospheric Infrared Sounder (AIRS) instrument provided an infrared snapshot of Iggy's cloud top temperatures on January 26, 2012 at 0611 UTC (1:11 a.m. EST). The AIRS image showed a large and rounded area of high, cold clouds, around the entire center of circulation.
When NASA's Aqua satellite passed over Cyclone Iggy (left) on January 26 at 611 UTC (1:11 a.m. EST) the AIRS instrument measured the cloud (purple) top temperatures. Thunderstorm cloud tops around the entire center of circulation were colder than -63 Fahrenheit (-52.7 Celsius) indicating strong storms.

The data also showed that strongest convection (rapidly rising air that condenses and forms the thunderstorms that make up the cyclone) is located slightly to the west of the center, because of easterly wind shear. The temperatures of those high cloud tops were colder than -63 Fahrenheit (-51.7 Celsius), which is a threshold scientists use to identify strong thunderstorms with heavy rainfall. This is an indication that Iggy will continue to strengthen.
The AIRS image also showed clouds to the southeast of Iggy that are associated with another low pressure area. That area of disturbed weather is over land and located south-southwest of Darwin.
Iggy is currently located in the Southern Indian Ocean, northwest of Western Australia. At 1500 UTC (10 a.m. EST), Tropical Cyclone Iggy was about 430 nautical miles (~495 miles/~796 km) northwest of Learmonth, Australia, near 16.8 South and 109.0 East. It was moving slowly to the southeast at 5 knots (~6 mph/~9 kph). Iggy's maximum sustained winds are near 45 knots (~52 mph/~83 kph) and it is classified as a tropical storm. Those tropical-storm-force winds extend out to 110 miles (177 km) from the center.
Iggy's approach has prompted the Australian Bureau of Meteorology to issue a cyclone and flood watch. Iggy is moving toward the Pilbara coast. The coastal communities between Whim Creek and Coral Bay will likely experience gusty winds and heavy rainfall on January 27 and 28. Rough surf is also expected along coastal areas including Christmas Island, the Kimberley and Pilbara coasts.
Iggy is forecast to continue strengthening as it moves southeast toward Western Australia. Sea surface temperatures along track are 28 to 29 degrees Celsius (~82 to ~84 Fahrenheit), which the Joint Typhoon Warning Center says is supportive of further development. It is expected to reach cyclone strength before moving to the south.

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...
