The present invention is a golf ball ejecting apparatus that comprises a sleeve and a main body featuring a solenoid system and surrounded by and attached by sealants to the sleeve. The main body comprises a solenoid-driven plunger, a guide tube, a power source, a housing for the power source, phototransistors, solenoid coil, tapered coil springs, insulating tape, a control circuit panel, a flag stick tube, a golf cup and an end plate. The end plate is positioned under the guide tube and serves as a bottom cover for the main body. The solenoid-driven plunger slides in the guide tube which is positioned under the flag stick tube. The golf cup is positioned above the flag stick tube. The insulating tape is wrapped around the solenoid coil which is wrapped around the flag stick tube. Tapered coil springs connect the power source to the solenoid coil. The control circuit panel is placed on the insulating tape and is connected to the phototransistors. The phototransistors are embedded in the housing for the power source and are actuated and are used to selectively actuate the golf ball ejecting system upon a quick removal of a shadow previously cast upon them. Upon triggering the phototransistors, an electrical circuit is established through the power source and the conductive strip, resulting in an exertion of an abrupt upward force by the solenoid coil on the solenoid-driven plunger.
