From  Hawaii Volcano Observatory

June 27th Lava Flow Observations: A Civil Defense overflight on Monday morning found that the leading edge of the June 27th lava flow had not advanced in the past 24 hours, although it was active along its northern margin. The flow lobe upslope and north of the leading edge advanced by 90 m (100 yards) since it was observed on Sunday morning. HVO plans to conduct an overflight of the entire June 27th lava flow field later on Monday.
