The solar eclipse observed by Clavius in A . D . 1567

چکیده
The careful description of the solar eclipse of A.D. 1567 by Clavius is used to derive limits to the Earth’s rotational clock error (∆T) of between 145 and 165 sec at this date. This result provides an important link between the ∆T curve as deduced from ancient and medieval eclipse observations and that obtained from telescopic data.

Temperature perturbations in the troposphere - stratosphere over Thumba ( 8 . 5 ◦ N , 76 . 9 ◦ E ) during the solar eclipse 2009 / 2010
Measurements of atmospheric temperature profiles in the troposphere and lower stratosphere were made over Thumba Equatorial Rocket Launching Station (TERLS) (8.5 N, 76.9 E) during a partial solar eclipse (22 July 2009) and an annular solar eclipse (15 January 2010). It was observed that during the partial solar eclipse, the temperature decreased by 2–3 C in the vicinity of the tropopause and in...
متن کاملThe solar eclipse and associated atmospheric variations observed in South Korea on 22 July 2009
A partial solar eclipse occurred in South Korea on 22 July 2009. It started at 09:30 a.m. and lasted until 12:14 LST with coverage of between 76.8% and 93.1% of the sun. The observed atmospheric effects of the eclipse are presented. It was found that from the onset of the eclipse, solar radiation was reduced by as much as 88.1 approximately 89.9% at the present research centre. Also, during the...

An experiment to search for short-period intensity oscillations in the solar corona was conducted during the total solar eclipse of August 11, 1999 in Esfahan, Iran. The intensity in the continuum, centered about 4700 Å and with a passband having a half-width of 190 Å, was recorded at a counting rate of 5 Hz using six low-noise Hamamatsu R647 photomultiplier tubes. We recorded intensity value...
متن کاملAttenuation of global ultraviolet and visible irradiance over Greece during the total solar eclipse
The variability of ultraviolet and photosynthetically active radiation during the total solar eclipse of 29 March 2006 was examined in this study. The measurements from NILU-UV multichannel actinometers at 7 stations of the Greek UV Network were used, where the maximum eclipse percentage ranged from 73.1% to 94.8%. In addition, 5 an extra instrument was established at a remote Greek island, Kas...
متن کاملUsing the ionospheric response to the solar eclipse on 20 March 2015 to detect spatial structure in the solar corona.
The total solar eclipse that occurred over the Arctic region on 20 March 2015 was seen as a partial eclipse over much of Europe. Observations of this eclipse were used to investigate the high time resolution (1 min) decay and recovery of the Earth's ionospheric E-region above the ionospheric monitoring station in Chilton, UK. At the altitude of this region (100 km), the maximum phase of the ecl...
