High Level C-Class Flares: A C8.3 Solar Flare took place near the western limb at 01:13 UTC Sunday morning. This was followed by a C9.0 Flare at 04:53 UTC. Both flares were centered around new Sunspot 1286. Because of its location, any further activity around this region will not be earth directed.Solar activity remains low with only C-Class flare activity taking place within the past 72 hours.
A new sunspot group now numbered 1286 quickly formed to the north of Sunspot 1280, but this region will soon be rotating onto the western limb. Elsewhere, A small new sunspot group numbered 1287 rotated into view on the southeast limb Saturday morning.
There will continue to be a chance for C-Class solar flares and about a 15% chance of an M-Class event according to the latest SWPC update.
CORONAL HOLES:
A coronal hole (CH474) in the southern hemisphere was in an Earth facing position on September 1. A recurrent coronal hole (CH475) in the northern hemisphere will likely rotate into an Earth facing position on September 8.

The HMI (Helioseismic and Magnetic Imager) HMI is an instrument designed to study oscillations and the magnetic field at the solar surface, or photosphere. HMI is one of three instruments on the Solar Dynamics Observatory; together, the suite of instruments observes the Sun nearly continuously and takes a terabyte of data a day. HMI observes the full solar disk at 6173 Å with a resolution of 1 arcsecond. HMI is a successor to the Michelson Doppler Imager on the Solar and Heliospheric Observatory. This is very much how the Sun looks like in the visible range of the spectrum (for example, looking at it using special 'eclipse' glasses: Remember, do not ever look directly at the Sun!). The magnetogram image shows the magnetic field in the solar photosphere, with black and white indicating opposite polarities.Source: NASA / SDO / HMI
