NASA's Terra satellite passed over Daphne at 1014 UTC (6:14 a.m. EDT or 10:14 p.m. local time, Auckland, New Zealand), and used infrared imagery from the Moderate Imaging Spectroradiometer (MODIS) instrument to visualize its cloud extent.

Like the infrared goggles used to see at night infrared satellite imagery can see cloud cover of tropical cyclones from space. The MODIS image showed Daphne to be more rounded and less elongated than it appeared in satellite imagery on April 2, indicating that wind shear had lessened. At that time, its minimum central pressure was 986 millibars.
On April 3 at 0300 UTC (April 2 at 11 a.m. EDT/3 p.m. local time, Auckland, New Zealand time), Tropical Storm Daphne had maximum sustained winds near 50 knots (57.5 mph/92.6 kph), up from 35 knots (40 mph/64 kph) on April 2. Daphne was located 744 nautical miles (856 miles/1378 km) east of Kingston Island, near 27.8 South and 178.0 West. Daphne was speeding to the southeast at 25 knots (28.7 mph/46.3 kph). As Daphne has moved, it has grown in size. Tropical-storm-force winds now extend as far as 300 nautical miles (345.2 miles/555.6 km) from the center, especially in the east and southern quadrants. Tropical-storm-force winds in the other quadrants appear to extend just further than 100 nautical miles (115 miles/185 km).
All warnings have been dropped for Fiji land areas, but mariners can expect rough seas between Fiji and New Zealand as Daphne continues moving southeast.
Forecasters at the Fleet Weather Center in Norfolk, Virginia are currently maintaining forecasts for tropical cyclones in the South Pacific. The current forecast takes Daphne on a south-southeasterly track over the next several days and keeps it away from New Zealand. Forecasters expect Daphne to begin weakening as it continues to move southeast as wind shear will increase and sea surface temperatures will drop.

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).
The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
