Center‐to‐Limb Variation of Solar Granulation from Partial Eclipse Observations

Height variation of the solar granulation

We analyze spectral scans of narrow-band images across the Na D2 line. They were obtained from disc centre of the Sun with our Fabry-Perot interferometer (FPI) in the Vacuum Tower Telescope at the Observatorio del Teide. The FPI was set to a bandwidth of 200 mÅ FWHM and the spectral stepwidth was 100 mÅ. Our aim is to study the variation of the granulation pattern with height in the atmosphere....

Dynamics of the solar granulation

Excellent spectrograms can yield observational insight in the dynamics of the solar surface not yet accessible to numerical simulations. We present results of the elaboration of a series of spectrograms taken at the center of the solar disk. Each of the spectrograms includes more than 250 granules, while the series covers a time of 12 min. Our main emphasis is to study the dynamics of the visib...

Solar radiation during a total solar eclipse

Solar eclipse-burn of macula.

THE following case is of interest in view of its association with the recent partial eclipse of the sun. 2695379, Guardsman W.S.S., 1st Btn. Scots Guards, aged 27 years, came to see me on July 12, 1945, complaining of obscured vision in the left eye. ;History.-No family history. Five years ago he was in Mersa Matruh for a year. During this time he was working in an outdoor-cookhouse. ToWards th...
