Ultraviolet Jets and Bright Points in the Solar Chromosphere. I. Search for One-to-One Relationships
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 = 1600 A, chromospheric jets observed in C I lines near λ = 1560 Å, and Ca II K2v 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 Å bright points and C I blue jets using data from the High Resolution Telescope and Spectrograph VI rocket flight, comparing 1600 A spectrohellograms 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.
