Analysis of the 9th November 1990 flare

[摘要] In this paper we present complete two-dimensional measurements of the observed brightness of the 9th November 1990 𝐻𝛼 flare, using a PDS microdensitometer scanner and image processing software MIDAS. The resulting isophotal contour maps, were used to describe morphological-cum-temporal behaviour of the flare and also the kernels of the flare. Correlation of the 𝐻𝛼 flare with SXR and MW radiations were also studied.
