NASA-NOAA's Suomi NPP satellite passed over the remnants of Tropical Depression Peipah on April 9 as the storm slowly approached the Philippines from the east. According to the Joint Typhoon Warning Center, Peipah is now not expected to make landfall in eastern Visayas until April 12.
The Visible Infrared Imaging Radiometer Suite or VIIRS instrument aboard Suomi NPP captured a visible, high-resolution image of the storm as it continued moving through the Philippine Sea. The storm appeared disorganized in the image, and the center was difficult to pinpoint on the visible imagery.
VIIRS is a scanning radiometer that collects visible and infrared imagery and radiometric measurements. VIIRS data is used to measure cloud and aerosol properties, ocean color, sea and land surface temperature, ice motion and temperature, fires, and Earth's albedo.
Using animated multispectral satellite imagery, the Joint Typhoon Warning Center observed weakening deep convection (thunderstorms were not developing as quickly) within a broad low-level circulation center.
An image from the Advanced Microwave Sounding Unit (AMSU) showed there is a curved band of thunderstorms over the northern semi-circle. There's also a weak band of thunderstorms over the southwester quadrant of the storm.
The AMSU-A instrument flies aboard NASA's Aqua satellite and is a 15-channel microwave sounder instrument designed primarily to obtain temperatures in the upper atmosphere (especially the stratosphere)
Tropical depression Peipah's maximum sustained winds were near 25 knots/28.7 mph/46.3 kph on April 8 at 1500 UTC/11 a.m. EDT. Peipah is centered near 9.1 north and 129.7 east, or 616 nautical miles/709 miles/1,141 km southeast of Manila, Philippines. The depression slowed down and was moving to the north-northwest at 5 knots/5.7 mph/9.2 kph.
Peipah is in a weak steering environment, that means there are no strong high or low pressure areas nearby to push it one way or another, so it is expected to track slowly in a northwesterly direction for the next several days.

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...
