Abstract (from CDS):

The source J1128+5925 was recently found to show strong intraday variability at radio wavelengths and its radio variability may come from interstellar scintillation. In the optical, the object was quiet in our 2007 monitoring session. Here, we report the results of our new optical monitoring of this source in 2008. In addition to confirming our 2007 results that the object did not display any clear variation on timescales from hour-day to month, we provide evidence that the object does not vary on timescale of one year, and it is probably intrinsically quiet in optical domain. Its very different behaviors in optical and radio regimes can be naturally explained if its strong radio variability comes from interstellar scintillation.
