Abstract
The recurrent nova (RN) M31N 2017-01e, with an inter-eruption period of just 2.5 yr, is the second most active nova yet discovered. As such, one might expect it to be surrounded by a visible nova super-remnant (NSR) akin to the one discovered around M31N 2008-12a, or to those around selected Galactic and Magellanic Cloud RNe. Here, we report that the deepest Hα observations of M31N 2017-01e yet collected still show no evidence for a surrounding NSR. We outline some potential explanations and consequences.
