摘要
Ultraviolet spectrograms and spectroheliograms of the solar chromosphere are used to test the suggestion of Dere, Bartoe, & Brueckner and Rutten & Uitenbroek that bright points in quiet Sun cell interiors observed at lambda = 1600 Angstrom, chromospheric jets observed in C I lines near lambda = 1560 Angstrom and Ca II K-2v bright points are associated with each other and that they are all manifestations of the same wave interaction in the nonmagnetic chromosphere. We search for spatio-temporal connections between 1600 Angstrom bright points and C I blue jets using data from the High Resolution Telescope and Spectrograph VI rocket flight, comparing 1600 Angstrom spectroheliograms and a cospatial C I Doppler shift map on a pixel-by-pixel basis. We find no direct evidence for spatial colocation of bright points and jets, not for instantaneous correspondence and also not when allowing for phase delays as long as 3 minutes. Also, the average brightness evolution and its rms fluctuation are not obviously different between sites of large C I blueshift and the remaining surface.
