- Аннотация: MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South African Astronomical Observatory, automatically started inspect of the ICECUBE Alert190104.36 error-box (23 57 19 dec=-25 21 57, r=1.23 taken from the IceCube-MASTER socket ) 36615 sec after notice time and 36655sec after trigger time at 2019-01-04 18:45:33 UT. The 5-sigma upper limit on our first (180s exposure) set is 18.4 mag IceCube publishied error-box differs from socket one (Kopper et al. GCN 23605) MASTER cover map will be available here http://master.sai.msu.ru/static/IC/MASTERIC190104.36.png There are the following sources in IceCube error box: 1) 4 blazars from Roma BZCAT 5BZBJ2350-2436 357.59720 -24.60083 0.193 16.2 , dist= 2.085 deg 5BZQJ2352-2825 358.22070 -28.43111 1.662 19.1 , dist= 1.797 deg 5BZQJ2353-2743 358.29776 -27.72378 0.889 17.9 , dist= 1.120 deg 5BZQJ2357-2451 359.34937 -24.85089 1.614 19.3 , dist= 2.261 deg 2) 3 known supernovae : LSQ12gdj, SN1993ah, PTF11klo 3) 62 xray sources 4) 75 radio-sources 5) 3297 galaxies inside 2.28 deg radii 6) 2 variable sources from AAVSO database VZ Scl 23 50 09.25 -26 22 52.6 (type : NL/VY+E) ATLAS18tyo 23 52 08.06 -27 48 07.7 (type : UG) MASTER Global Robotic Net continues inspection. ==================================================================== The error-box center's galactic latitude b = -78 deg., longitude l = 40 deg. The observations started at zenit distance = 41 deg. The moon ( 2 % bright part)was below the horizon ( The altitude of the Moon was -22 deg ( 2 % bright part) Observations started at twilight, the sun altitude was -11.4 deg.
