System 92S didn't have very strong winds when it passed over the coastal city of Vohemar on Madagascar's northeastern coast over the last couple of days, but street flooding was reported.
Rainfall derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments shows that numerous intense storms were dropping rainfall at a rate of over 50mm/hr (~2 inches) on February 25, 2012. TRMM Precipitation Radar data also showed that some powerful storms within the area reached to heights of over 15km (~9.3 miles).

A rainfall analysis was made at NASA's Goddard Space Flight Center, Greenbelt, Md. using data from a near-real time Multi-satellite Precipitation Analysis (TMPA). TRMM-based near-real time Multi-satellite Precipitation Analysis (TMPA) data are used to monitor rainfall over the global Tropics. This analysis showed that during the past week the tropical cyclone contributed to flooding rainfall totaling over 280mm (~11 inches).
The TRMM satellite passed over this area on February 25, 2012 at 2025 UTC before this stormy area moved over northeastern Madagascar. Rainfall derived from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments showed that numerous intense storms were dropping rainfall at a rate of over 50mm/hr (~2 inches). TRMM Precipitation Radar data also showed that some powerful storms within the area reached to heights of over 15 km (~9.3 miles).
On February 28, 2012 at 1011 UTC (5:11 a.m. EST) the Atmospheric Infrared Sounder (AIRS) instrument on NASA's Aqua satellite captured an infrared image of System 92S's eastern half, bringing rains to west-central Madagascar. The storm's center is over the waters of the Mozambique Channel and was not in line with the AIRS instrument's view. The eastern edge of the storm, however was bringing gusty winds and heavy rainfall to west-central Madagascar.
System 92S filled up the northern half of the Mozambique Channel, stretching from Madagascar in the east, to Mozambique to the west of the channel. Both places were experiencing gusty winds and moderate to heavy rainfall on February 28, as System 92S continues to consolidate and strengthen.
On February 28, 2012, System 92S's center was near 16.1 South and 45.2 East, near the coastline of northwestern Madagascar, but over the waters of the Mozambique Channel. It is moving to the southwest near 7 knots (8 mph/13 kph).
Visible imagery from NASA's Aqua satellite showed the bulk of System 92S's clouds were pushed to the west of its center, as a result of wind shear. Because water vapor imagery revealed a lot of moisture over the Mozambique Channel, and the sea surface temperatures are well over the 26.6C (80F) threshold needed to maintain a tropical cyclone, conditions are improving for further development. Wind shear is also expected to ease, which will help with further intensification as System 92S moves further into the Mozambique Channel.
The Joint Typhoon Warning Center gives System 92S a high chance for becoming a tropical depression in the next 24 hours.Text Credit: Hal Pierce/Rob Gutro

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
