[vsnet-alert 22419] Re: Bl3-6 brightening

[bmonard at mweb.co.za]

This object has been seen around 16.3V +/- 0.3 since regular symbiotic star observations started at the Bronberg Observatory in 2004. The first sign of the present outburst was noted on 2/8/2018 from observations in Ic.

Due to the nearness of a brighter star to its East, precise photometry in V during the normal state is quite difficult with small telescopes.


Herewith some recent photometry:

JD  //  CCD-V	CCD-Ic

2458261.49		12.24

2458333.25		11.56
2458346.37	14.87	11.52
