HD 141569A sports a dusty disk in the throes of transition from primordial proto-planetary disk to Beta Pictoris-like debris disk. As such stars are rare, it has been much studied and modeled. It also happens to be part of a 5 Myr old triple system with two M-type weak-line T Tauri star companions. Despite many studies over the last five years, the amount of mid-infrared emission from the disk around HD 141569A is unclear. Published ground-based 12 and 18 micron photometry disagree with each other and with IRAS results. I propose MIPS photometry of HD 141569 to help resolve the confusion over the flux density from this star and to look for small amounts of dust around the companions at 24 micron.
