The National Eclipse Weather Experiment (NEWEx) was a citizen science project for atmospheric data collection from the partial solar eclipse of 20 March 20. Its role as a tool for schools outreach is discussed here, in seeking to bridge the gap between self-identification with the role of a scientist and engagement with science, technology, engineering and mathematics subjects. (The science dat...
Solar eclipses represent a natural and unexpected event for plants that can potentially affect photosynthetic performance at the individual level. This effect, however, has seldom been evaluated. Here, we measured impact of total solar eclipse on rate different tree species—located in Bosque Fray Jorge National Park, Chile—with varying degrees shade tolerance. Specifically, assessed whether rap...
Pathfinder Normalized Difference Vegetation Index (NDVI) derived from Channel 1 (Red) and Channel 2 (near-infrared) of Advanced Very High Resolution Radiometer (AVHRR) onboard NOAA 14 became abnormally high for the 10-day composite from February 11 to 20 in 1999 for Western Australia. There was a solar eclipse in the satellite path on February 16 about the same time when NOAA 14 was above the e...
We observe two secondary eclipses of the strongly irradiated transiting planet WASP-33b, in the Ks band at 2.15μm, and one secondary eclipse each at 3.6μm and 4.5μm using Warm Spitzer. This planet orbits an A5V δ-Scuti star that is known to exhibit low amplitude non-radial p-mode oscillations at about 0.1% semi-amplitude. We detect stellar oscillations in all of our infrared eclipse data, and a...
