HST/NICMOS images of the class I protostar TMR-1 (IRAS04361+2547) reveal afaint companion with 10.0" = 1400 AU projected separation. The centralprotostar is itself resolved as a close binary with 0.31" = 42 AU separation,surrounded by circumstellar reflection nebulosity. A long narrow filament seemsto connect the protobinary to the faint companion TMR-1C, suggesting a physicalassociation. If the sources are physically related then we hypothesize thatTMR-1C has been ejected by the protobinary. If TMR-1C has the same age anddistance as the protobinary then current models indicate its flux is consistentwith a young giant planet of several Jovian masses.
