Hi all,

Is it then interesting to continue observing this object in time series?

Regards,
Josch

ASASSN-18nq: eclipsing object

Josch Hambsch has reported observations on June 24 and 25.
The object was bright (14.8-14.9) and showed 0.4-mag eclipses.
The period appears to be long (slightly more than 1.0 d or its half). The object is clearly unusual, if all (ASAS-SN and Hambsch) observations recorded the same object.
