Figure 1: MDI magnetogram of the studied region taken at 03:04 UTC on June 14 in 1998. The white contours correspond to bright lanes seen in the averaged image of the 1216 Å passband. |

Figure 2: Panels A-D: The average intensity image of the 1216 Å passband, and maps of Fourier power in period ranges of 4-16 min, 20-40 min, and 42-75 min. Panels E-H: similar to panels A-D, but for the 195 Å passband. The regions outlined in yellow are analyzed with a wavelet transform. |

Figure 3: Wavelet power spectra of the 1216 Å ( left side) and 195 Å ( right side) passbands for the three selected regions (corresponding to the three double-rows). a) The running difference light curve. b) Time/period variation of the wavelet power spectrum. Cross-hatched regions indicate the ``cone of influence''. The darker parts represent higher power, and the contours correspond to the 99% confidence level. c) Global wavelet. |
