AMON IceCube-HAWC_200202A: MASTER optical inspect
Abstract
MASTER Global Robotic Net (http://observ.pereplet.ru, Lipunov et al., 2010,Advances in Astronomy,v. 2010, 30L) observed IceCube-HAWC 200202A (error-bx AMON GCN 26963) since 2020-02-02 21:50:53 UT.o MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) was pointed to the IceCube Alert 200202.33 (trigger No 20200202075852,13h 21m 12.00s , +12d 42m 36.0s, R=0.3) errorbox 49921 sec after trigger time at 2020-02-02 21:50:53 UT, with upper limit up to 17.2 mag. Observations started at twilight. The observations began at zenith distance = 44 deg. The sun altitude is -11.8 deg. MASTER-Tunka robotic telescope located in Russia (Applied Physics Institute, Irkutsk State University) was pointed to the IceCube Alert 200202.33 errorbox 50850 sec after trigger time at 2020-02-02 22:06:22 UT, with upper limit up to 18.2 mag. The observations began at zenith distance = 39 deg., sun altitude was -24.6 deg. MASTER-SAAO robotic telescope located in South Africa (South African Astronomical Observatory) was pointed to the IceCube Alert 200202.33 errorbox 53716 sec after trigger time at 2020-02-02 22:54:08 UT, with upper limit up to 20.4 mag. The observations began at zenith distance = 76 deg., sun altitude was -41.2 deg. MASTER-IAC robotic telescope located in Spain (IAC Teide Observatory) was pointed to the IceCube Alert 200202.33 errorbox 59842 sec after trigger time at 2020-02-03 00:36:14 UT, with upper limit up to 21.5 mag. The observations began at zenith distance = 69 deg.,sun altitude was -75.5 deg. The error-box galactic latitude b = 73 deg., longitude l = 332 deg. Auto-detection system marginally found possible OT in SDSS J132141.10+125747.3 with m ~ 19.6 (host galaxy photom.z~0.47749). But hand analysis do not strong supply this resuts. There is QSO SDSS_J13210+1237 in error-box, but it didn't change the brightness Reduction and analysys of galaxy clusters inside error-box will be continued.
