THE PRESENT INVENTION GENERALLY RELATES TO A PORTABLE DETECTION DEVICE (1), FOR AUTOMATICALLY DETECTING FLASHES OF LIGHTNING. A PHOTO-DETECTOR (11) IS APPLIED TO FRONT-END OF THE SYSTEM AS SENSING ELEMENT FOR THE LIGHTNING FLASH. THE DEVICE (1) USES FIBER OPTIC AS ITS TRANSMISSION SYSTEM (12) TO TRANSMIT THE DATA FROM THE PHOTO-DETECTOR (11) TO THE ANALOG RECEIVER (13) AT THE OTHER END OF THE FIBER OPTIC. A PROGRAMMABLE LOGIC CONTROLLER (14) THAT IS PART OF THE SYSTEM USED TO COLLECT AND STORE THE DATA WITH THE TIME AND THE DATE OF OCCURRENCES AND THIS DATA CAN BE VIEWED OR RETRIEVED THROUGH THE PERSONAL COMPUTER (15). THE SYSTEM CAN BE OPERATED IN TWO MODES NAMELY OFFLINE AND ON-LINE MODES. IN THE OFF-LINE MODE, THE SYSTEM IS OPERATING INDEPENDENTLY TO RECORD THE DATA AT DESIGNATED AND REMOTE SITE. THERE IS NO COMPUTER CONNECTED TO THE SYSTEM DURING ITS DATA RECORDING ACTIVITY. THE SYSTEM WILL RECORD THE LIGHTNING ACTIVITIES FOR A PREDETERMINED PERIOD. AFTER THIS PERIOD, THE USER CAN COME AND COLLECT IT. THE PERSONNEL COMPUTER (15) IS THEN CONNECTED TO THE SYSTEM TO RETRIEVE THE DATA. IN THE ON-LINE MODE, THE SYSTEM IS LINKED TO THE SERVER DATABASE DIRECTLY VIA AN INTERNET. MANY SYSTEMS CAN BE LINKED TO THE SERVER DATABASE. THE DATA IS RECORDED AND COMPILED AUTOMATICALLY AND CONTINUOUSLY TO THE SERVER DATABASE.(FIG 1)
