MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) was pointed to the FRB 181228A ( Ferah et al., ATel #12335 ) 17723 sec after trigger time at 2018-12-28 18:44:13 UT, with upper limit up to 22.0 mag. Observations started at twilight, immediately after sunset. The observations began at zenit distance = 43 deg. The sun altitude is -11.0 deg.
MASTER-OAFA robotic telescope located in Argentina (OAFA observatory of San Juan National University) was pointed to the FRB Alert181228.58 57672 sec after trigger time at 2018-12-29 05:50:03 UT, with upper limit up to 19.0 mag. The observations began at zenit distance = 24 deg. The sun altitude is -33.0 deg.
The galactic latitude b = -60 deg., longitude l = 98 deg.
MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net",
Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 06h 09m 25.17s -47d 32m 48.6s on 2018-12-29.34613 UT. The OT unfiltered magnitude is 17.9 m.
The OT is seen in 2 images. There is no minor planet at this place. OT is also visible on 3 MASTER-SAAO images today night.
The OT discovered in PGC 499631 Galaxy, approximately 1.5 degree far away from FRB error line.
We also see this object in a slightly weaker (by ~ 0.5 magnitude) condition on the images obtained 2018-12-13 .
We have reference image without OT on 2017-11-11.33303 UT with magnitude limit in 'BLANK' filter 19.9m.
Spectral observations are required.
