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.
We have reference image without OT on 2017-11-11.33303 UT with magnitude
limit in 'BLANK' filter 19.9m.
The Possible Super Nova discovered in PGC 499631 Galaxy (OT off set from
galaxy are 0.4W 2.5N), approximately 1.5 degree far away
from FRG errorline. Its not coonected with FRB.
Spectral observations are required.
