Predicted N-band flux as a function of solar system absolute magnitude H_V for all observable NEOs from the NASA-IRTF during a given observing semester. The top axis is the estimated diameter from H_V assuming a 15% albedo in the A. W. Harris & J. S. V. Lagerros (2002) relationship. Each circle’s color indicates the visible magnitude of the NEO at the time it reached peak in brightness. Yellow represents fainter objects (larger visible magnitude), while purple represents brighter ones.
