We report additional R and H-alpha photometry of the novae candidates M31N2018-03a and M31N2018-03b (ATel#11381). The images were obtained with the 2m RCC telescope (2018 03 09 UT) and 50/70 cm Schmidt telescope (2018 03 11 UT) at NAO Rozhen, Bulgaria. The magnitudes are:
M31N 2018-03a
2018 03 09.785 UT, R = 16.26 +/- 0.01, 2mRCC
2018 03 09.804 UT, Ha = 15.95 +/- 0.05, 2mRCC
2018 03 11.738 UT, R = 16.14 +/- 0.02, 50/70cm
M31N 2018-03b
2018 03 09.781 UT, R = 19.01 +/- 0.08, 2mRCC
2018 03 09.797 UT, Ha = 18.3 +/- 0.2 , 2mRCC
2018 03 11.737 UT, R = 19.21 +/- 0.12, 50/70cm
Further observations are required.
