CCD visual‐magnitude light curve for Var Her 04. Data are from the AAVSO and contain only CCD+V validated observations. Data have been rebinned in 1 day wide bins. Error bars represent the dispersion of the observations within that bin. The mean quiescent magnitude of ﹩V=16.5﹩ mag, as determined from the points at ﹩t> 250﹩ days, is marked by the dashed line. This is not the quiescent level of the outbursting Var Her 04 but is the visual magnitude of the unrelated line‐of‐sight foreground M star. The times of the four MIPS and two IRAC observations are marked by the vertical lines.
