V618 Sgr, a possible symbiotic star, has recently started a considerable
brightening as shown below: 

JD / CCD-V / CCD-Ic
2457953.40	15.25	11.12
2457961.40	15.12	11.07
2457979.37	14.84	11.12
2457984.36	14.27	11.07
2457991.35	13.88	11.06
2457999.27	13.68	11.06

The nearly constant I magnitudes point at the accretor, probably a WD, as the
eruptor.

This is the first observed eruption of this object since regular observations
started in 2004 at the Bronberg Observatory.
