TCP J05390410+4748030: likely dwarf nova outburst (11.3 mag) in Auriga

TCP J05390410+4748030 (UG:)

Discovery details:
R.A. 05h39m04.10s, Decl. +47°48'03.0" (J2000.0)
2019 Mar. 14.4227 UT, 13.3 mag (CCD, unfiltered)
Discoverer: Yuji Nakamura (Kameyama, Mie, Japan)

2019 03 14.4227 UT
Yuji Nakamura, Kameyama, Mie, Japan, reports his discovery of this TCP (mag 11.3) in Aur on a CCD frame taken on 2019 Mar 14.4227 UT (limiting mag 13.0) using a 135mm F4.0 lens. The object was not shown on a frame taken on 2019 Mar 09.4284 UT (limiting mag 13.0). There is a 19.2 mag star USNO-A2.0 1350-06029095 on this position.

2019 03 14.65 UT
Gaia DR2 position end figures for the abovementioned star USNO-A2.0 1350-06029095 are 04.103s, 00.71" (equinox J2000.0, epoch 2015.5; Gmag. 19.67, parallax 3.0826 ± 0.5239 mas, distance ~0.3 kpc). Other designations are USNO-B1.0 1378-0184085, GSC2.3 NAO9008900, PSO J053904.098+474800.708, GALEX J053904.0+474800, AllWISE J053904.08+474759.9, WDJ053904.11+474800.65. The transient is probably a dwarf nova outburst with an amplitude of about 8 magnitudes (WZ Sge type?).
*** Spectroscopy as well as multiband and time-resolved photometry are strongly recommended. ***

Thank you Patrick for this

Thank you Patrick for this new challenge

I made a visual estimation of this new nova: +11.5 - UTC 2019/03/14 19:25


TCP J05390410+4748030

Hello! I'll try to image it tonight. Are the comps up yet? My camera is 12'x18' so I may have to offset the target if the comps are a bit away from it.Best regards.

Dwarf nova outburst, not a nova eruption

My pleasure, Michel. :-)

Please note that this object is obviously a dwarf nova and not a nova.

Clear skies,
