Fits to the Q1R dense ring in light curve data taken with TUHO and TAOS II telescopes, from top to bottom. TAOS II data are stacked every six images. These light curves are plotted as a function of the time in seconds relative to the local closest approach (C/A), with a different y-axis scale in the rightmost panel in each row (dense part of Q1R). The green vertical dashed lines represent the theoretical times for the Q1R and Q2R rings. Note: although marginal, the two data points that detect the Q1R ring in the TAOS II light curve are statistically significant at the 4.2-σ level.
