We report the observations of the updated localization with GLADE(Dalya et al.,
2018, MNRAS, 479, 2374) catalogue of the gravitational event S190426c (The LIGO Scientific Collaboration and the Virgo Collaboration, GCN 24277,24237) with the Yaoan High Precision Telescope at Yaoan Observation Station(in Yunnan Province, China(101.1811¡ã E,25.528¡ãN)), Purple Mountain Observatory.

We obtained images of 48 galaxies in Rc band with exposure time 120s and calibrated to the PPMX catalogue (Roeser, 2008) .No obvious transient has been identified. The list of the observed/inspected targets and its 5-sigma magnitude limit  is given below.
