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.
