MASTER Global Robotic Net (http://observ.pereplet.ru, Lipunov et al.,
2010,Advances in Astronomy,vol. 2010, 30L)
started LIGO/Virgo S190425z (Singer et al. GCN 24168)
inspection at 2019-04-25 09:10:18 UT (Lipunov et al. GCN 24167) at
MASTER-OAFA (Argentina).
MASTER-OAFA started PS19qp (Smith et al., GCN 24210 ) at 2019-04-26
01:56:40.
Looking at our old images AT2019ebq / PS19qp, we
found a very recent inspection of this field due to the neutrino BNO alert
3 weeks ago and automatical Circular (not published yet).
To establish a possible connection of this supernova with neutrinos, it is
extremely important to determine the age of the supernova AT2019ebq /
PS19qp . Thus the object is not associated with LIGO/Virgo S190425z but
may be connected with BNO Alert190405.62 .
Below you can find automatic Circular (not published yet):
MASTER-Kislovodsk robotic telescope (Global MASTER-Net:
http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy,
vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar
Station of Pulkovo observatory) was pointed to the BAKSAN Alert190405.62

2019-04-05 20:29:29 UT, with upper limit up to 19.2 mag. The observations
began at zenit distance = 83 deg. The sun altitude is -39.9 deg.
MASTER-Tavrida robotic telescope located in Russia (Lomonosov MSU, SAI
Crimea astronomical station) was pointed to the BAKSAN Alert190405.62
28940 sec after trigger time at 2019-04-05 23:00:45 UT, with upper limit
up to 19.1 mag. The observations began at zenit distance = 63 deg. The
sun altitude is -37.1 deg.
MASTER-SAAO robotic telescope located in South Africa (South African
Astronomical Observatory) was pointed to the BAKSAN Alert190405.62 1 days
39324 sec after trigger time at 2019-04-07 01:53:49 UT, with upper limit
up to 19.2 mag. The observations began at zenit distance = 34 deg. The
sun altitude is -38.5 deg.
MASTER-OAFA robotic telescope located in Argentina (OAFA observatory of
San Juan National University) was pointed to the BAKSAN Alert190405.62 1
days 54872 sec after trigger time at 2019-04-07 06:12:57 UT, with upper
limit up to 18.0 mag. The observations began at zenit distance = 49 deg.
The sun altitude is -56.9 deg.
The galactic latitude b = -60 deg., longitude l = 98 deg.

The follow up spectral and photometric observations of AT2019ebq/PS19qp
are required.
