摘要：

1H 0323+342 is a rather radio-loud narrow-line Seyfert 1 galaxy (NLS1) with gamma-ray emission. Optical observations were carried out in B and R bands which covered 6 nights in 2011 to obtain light curves of 1H 0323+342. The difference image subtraction method was used to deal with the data of 1H 0323+342 because of the existence of extended host galaxy. Optical variability on day timescale was reported here. We also monitored the first gamma-ray NLS1 SDSS J094857.3+002225 and confirmed the existence of intranight optical variability (INOV). These indicated the existence of a relativistic jet in these NLS1s. (C) 2015 Elsevier B.V. All rights reserved.
