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

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...
