Near real-time monitoring of UT1 with geodetic VLBI

We give a short overview on the current status of near real-time monitoring of UT1 with geodetic VLBI. The use of real-time data transfer together with automated correlation and data analysis makes it possible to derive final dUT1-results with very low latency. The agreement with IERS C04 results is on the level of 30 msec. It is even possible to determine time series of dUT1 during ongoing 24 h IVS-sessions. The concept is highly relevant for future VLBI2010 operations.
