We have begun to model our data using radiative transfer code, in an attempt to simultaneously fit both the imaging data and the spectral energy distribution. We have noticed a possible discrepancy between the latest photometric values between 1 and 5 microns, and values obtained earlier. The photometric brightness and image appearance in the HH 30 system has been noted, so that a similar behavior in IRAS 23077+6707 seems likely. The existing SpeX cross-dispersed [SXD+LXD] is of moderately low quality, and should be re-done with longer exposure times. At least 3 epochs of imaging data should be obtained, in order to investigate the variability more fully. This is what is proposed here for 2023A, while more time will be requested in 2024B. The data obtained would justify proposals to the Hubble Space Telescope, and James Webb Space Telescope. PROGRAM_ABSTRACT_END
