Association of Coronal holes with large scale Solar Magnetic fields

Shelke, R. N; Pande, M. C (Astronomical Society of India, 1984-12)

Association of coronal holes with large scale solar magnetic fields has been investigated. It is concluded that coronal holes always form in the large unipolar megnetic field patterns, and no specific polarity rule holds ...
Coronal hole oscillations inferred from the SDO/AIA data

Hegde, M; Hiremath, K. M; Doddamani, V. H (Elsevier B.V, 2014-07-15)

With high temporal resolution (12 sec) of about two hours duration, data of a coronal hole structure in 171°A, 193°A and 211°A taken from SDO/AIA images is considered for examination of oscillations. After estimating the ...
Statistical study of network jets observed in the solar transition region: a comparison between coronal holes and quiet-sun regions

Narang, Nancy; Arbacher, R. T; Tian, H; Banerjee, D; Cranmer, S. R; DeLuca, Ed E; McKillop, S (Springer, 2014-04)

Recent IRIS observations have revealed a prevalence of intermittent small-scale jets with apparent speeds of 80 – 250 km s−1, emanating from small-scale bright regions inside network boundaries of coronal holes. We find ...
