Excerpt:
"... we discovered a new transient source, most likely a nova, in
the Local Group galaxy NGC 3109. To the best of our knowledge,
this is the first nova candidate discovered in NGC 3109.
ASASSN-18gb (AT 2018akx) was discovered in images obtained on
UT 2018-03-22.77 at V~17.5 mag. We do not detect (V>18.6) the
object in images taken on UT 2018-03-20.92 and before. An image
obtained on 2018-03-23 by J. Brimacombe confirms the discovery of
the transient. This figure

shows the archival DSS image of the host (left) and the confirmation
image (right). The red circle has a radius of 5" and is centered on
the position of the source in the confirmation image."

Clear skies,
Patrick
