| 内容記述 | We present a comparative analysis of the chromospheric solar limb prolateness, using strictly simultaneous H-alpha, ground-based observations and HeII space-based observations. The typical prolateness is found to be DeltaD/D = 5.5 x 10(exp -3) in HeII and 1.2 x 10(exp -3) in H-alpha. The first measurements in the 30.4 nm HeII line over a period of two years. as well as coronal data, are discussed to explore further the origin of the prolateness and its possible consequences. |
