NICER observation list: Target ID 561507

A recent 5-month NICER monitoring campaign of 4 'quiescent' Swift-BAT blazars reveals that variations in the 0.3-2 keV band are detected on three distinct timescales, but that the fractional variability is <25% and decreases on longer timescales, implying low-amplitude variability for all sources and showing very little to no variability on monthly timescales, which is in stark contrast to previous studies that show that blazars are highly variable in the X-rays over a wide range of timescales. As a follow-up to this campaign, we propose multi-cycle NICER observations of these 4 BAT blazars as well as of 2 additional blazars whose variability is not detected by the BAT, in order to characterize the long-term variability, search for flares, and obtain high-quality time-averaged spectra.
