Energetic activity from the sun constantly produced huge of mass and radiation. Hence, it is important to monitor in real time for space weather forecasts. The solar activity such as the phenomena of flares and Coronal Mass Ejections (CMEs) closely associated with the production of solar burst. This solar burst detected by radio spectrometer on the ground station namely CALLISTO. A new algorithm was developed to classify the radio burst type II and type III as automatically. To design an automatically algorithm frequency drift was used as the main parameter. There are three steps involved in this process, there are preprocessing, identification and classification. Auto calculation of frequency drift rate burst on spectra was obtained from frequency channel (df) and time channel (dt). Approximately 1839 dynamic spectrums obtained and analyzed on 8th January 2014. was From the result, all the spectrums tested can be identified (burst type). In future, this developed system could be upgraded with a minimum error of detection of a burst. This finding will benefit to CALLISTO user potential to apply for solar monitoring via web base or mobile apps, especially astronomer to screen the solar activity.
