Top: Bolometric luminosity calculated for photons escaping to infinity with energy exceeding 10ℏeB0/mec. Here, ct/rg corresponds to time of photon emission; not time of photon reception. Light-travel-time effects are thus absent in this light curve. Bottom: Instantaneous open (BH-Inf), closed (BH-Disk), and total magnetic flux threading the BH horizon, as in Fig. 4.
