Intensity maps of the normalized Orionids (left) and η-Aquariids (right) activity as measured by the CMOR 29 MHz system since 2002. For each apparition of the shower, the activity profiles of Figs. B.2 and B.1 are normalized by the maximum ZHR_v value determined in the previous section. This is represented by the black curve to the right of each map. Timing of maximum activity are highlighted by light colors (yellow to orange), while low meteor rates (or the absence of measurements) are represented by dark colors (purple to black).
