Digital Sunspot Counting For Langkawi National Observatory In White Light Full Disk

For over 400 years, sunspot observation has been consistently collected and it has become the longest-running experiment and still ongoing scientific project. Sunspot numbers are manually counted based on direct visual observation or drawing it through the projection method. Langkawi National Obser...
