The variations of phase and amplitude of a subionospheric transmitted signal at frequency 19.8 kHz from North West Cape, Australia (latitude: 21.82◦S; longitude: 114.16◦E) measured at Kolkata (latitude: 22.56◦N, longitude: 88.5◦E) during the period of solar eclipse (partial, 91.1%) on July 22, 2009 will be presented in this paper. The variations in amplitude are quite significant than the usual...
The solar eclipse has a great influence on the variability of ionosphere because obscuration radiation. Using equatorial electrojet (EEJ) and plasma measurements from Swarm, zonal winds Michelson Interferometer for Global High-resolution Thermospheric Imaging Ionospheric Connection Explorer mission, electron density Constellation Observing Systems Meteorology, Ionosphere, Climate temporal respo...
Solar retinopathy is a retinal injury caused by direct or indirect sun-gazing and solar eclipse observation without protection. Subtle changes in the retinal damage might not be evident on fundus photography and fluorescein angiography. A 40-year-old veteran suffered from paracentral scotoma in his left eye shortly after unprotected solar eclipse observation about 1 month earlier. His visual ac...
