However, the region retains its beta-gamma-delta configuration and is currently undergoing new flux emergence which is forming an unusual negative polarity halo around the positive leader spot. This emergence is also coincident with some bright H-alpha emission indicating possible sheering. Major Flare Watch shall remain in effect for a further 24 hours due to increased likelihood of an M5 flare or greater. The position of NOAA 12158 on 10-Sep-2014 at 13:18 UT is: N15E06, ( -96", 129" ) See http://www.SolarMonitor.org for images and http://solar.physics.montana.edu/max_millennium/ops/observing.shtml for a description of the current Max Millennium Observing Plan.
