Short summary
Short summary
This article reports the first observations of 32 type II bursts in cycle 25 from May 2021 to December 2022. The impacts of space weather on ionospheric total electron content (TEC) enhancement, as measured by the rate of change of TEC index (ROTI), are also studied. According to the current analysis, 19 of 32 type II bursts are connected with imminent space weather occurrences, such as radio blackouts and polar cap absorption events, indicating a high likelihood of space weather disturbance.

Short summary
This paper summarises the results obtained by analysing the solar radio bursts detected by a single spectrogram installed at the University of Rwanda through the collaboration and the initiation of the space weather initiative. We aimed to show that data gaps in the African continent can be tracked by the deployment of cheap spectrograms, but their regular maintenance matters. In addition, the results show that the observation at a single station is a clue to studying space weather hazards.
