Abstract

We carried out a pilot 1.3-cm IDV observations of two dozens of AGNs at Urumqi from 23 to 25 November 2011. Six sources, namely J0136 + 4751, J0217 + 0144, J1058 + 0133, J1751 + 0939, J1833 − 2103 and DA193 were detected as IDV sources at a 99% confidence level (about 3 σ level). The weather was fine during the observation period, but the system noise after calibration remained which could be due to the data sampled are relatively sparse for each source in the observations.
