Last night I had 17 moth species including 2 new ones: Scalloped Oak and Ash-bark Knot-horn. The prize was a Burnished Brass. 

  I'm having camera problems at the moment, the camera and flash suddenly don't like each other and the result is gross underexposure. The correction requires a high ISO. Having spent hours trying to figure out the problem and failing, I'm taking the outfit to local expert Tony at Camercal tomorrow morning.

  On Saturday I found 2 medieval artefacts and a small Roman coin, a GLORIA EXERCITVS nummus of the house of Constantine:

GLORIA EXERCITVS nummus

AD 335-41, 14mm diameter, weight 1g.

obverse: CONSTANTINVS MAX AVG (Constantine the great Emperor)

reverse: GLORIA EXERCITVS (great army) two soldiers standing either side of two standards
