<p class="Normal1"><strong>Abstract: </strong>Total solar eclipse on March 9, 2016, could only be observed optimally in Indonesia. It’s the best condition to analyze the intensity fluctuation of corona. Intensity data retrieval can  be done under the total solar eclipse because the corona are visible at that time. The data retrieval did not use coronagraph, but DSLR camera which connected to a telescope. This became a simple acquisition system. Intensity analysis was obtained by using IRIS 5.59 software and it has  200 pixels length in the corona. Height by intensity based data between 8,895.58-15,099.72 was equivalent to 4,000 km – 40,000.46 km from the defined solar’s surface.</p><p class="Normal1"> </p><p class="Normal1"><strong>Keywords:</strong><em>  </em>Total Solar Eclipse, Corona Image Intensity</p><p class="Normal1"> </p><p class="Normal1"><strong>Abstrak:</strong> Gerhana Matahari total 9 Maret 2016, hanya bisa diamati secara optimal di Indonesia. Kejadian gerhana ini merupakan kondisi terbaik untuk menganalisis fluktuasi intensitas korona. Pengambilan data intensitas bisa dilakukan ketika terjadi gerhana Matahari total karena korona terlihat pada waktu itu. Pengambilan data tidak menggunakan koronagraf, melainkan menggunakan kamera DSLR yang terhubung ke teleskop. Metode ini merupakan metode pengambilan data yang menerapkan sistem akuisisi sederhana. Analisis intensitas korona dilakukan dengan menggunakan software IRIS 5.59 dan menggunakan data 200 piksel di korona. Hasil penelitian menunjukkan bahwa nilai intensitas korona berada pada rentangan 8.895,58-15.099,72, dimana nilai ini berada pada ketinggian 4.000 km - 40.000,46 km dari permukaan Matahari.</p><p class="Normal1"> </p><p class="Normal1"><strong>Kata kunci :</strong> Gerhana Matahari Total, Intensitas Citra Korona</p>

AbstractWe present the results of the analysis of a movie taken over a small field of view in the intermediate corona at a spatial resolution of 0.5“, a temporal resolution of 1 s and a spectral passband of 7 nm. These CCD observations were made at the prime focus of the 3.6 m aperture CFHT telescope during the 1991 total solar eclipse.

AbstractHigh resolution images, obtained during July 11, 1991 total solar eclipse, allowed us to estimate the degree of solar corona polarization in the light of FeXIV 530.3 nm emission line and in the white light, as well. Very preliminary analysis reveals remarkable differences in the degree of polarization for both sets of data, particularly as for level of polarization and its distribution around the Sun’s limb.

Carriacou is a small island situated about twenty miles to the north of the island of Grenada, the chief of the Windward group, and furnished an excellent site for the observation of the last solar eclipse. Most of the observers sent by the Eclipse Committee of the Royal Society to the West Indies in August of last year remained at Grenada, or on the small islands in its immediate vicinity, whilst Mr. Maunder and myself occupied the more distant northern station, where the totality was slightly diminished in duration. The work proposed for Mr. Maunder was to secure a series of photographs of the corona, with exposures of 40s. and under, and also to obtain two photographs of the spectrum of the corona with the longest exposures possible.
