The Sunspot no. 1093 on the earth facing side of the sun emitted a Coronal Mass Ejection on August 7
On August 7,1825UT The magnetic fields around1093 became unstable which triggered a Class M-1 Solar flare
which is indeed a strong flare as on the X-ray Flux scale
The 5 min data from GOES X-ray flux on 1825UT on 7th August showed a X ray flux less than 10 raised to -5 W/m^ . A Coronal Mass Ejection hurled from 1093 after the solar flare was emitted
But fortunately this ejection was away from Sun-Earth line so the ejection wasn't focused on earth.
But some charged particles with tons of plasma will head towards earth on Aug 9th-10th and will result in interraction with magnetic field and Aurora display around poles. Since the emission was not direct on earth, the Aurora activity will be limited in the polar regions and also in the upper 60N and lower 60S on nights of 9th and 10th August

You can see the active CME on the left central part of Sun
This will not be ANY SIGNIFICANT EVENT
The active 1093 spot will be rotating towards Earth and by this weekend to begin of next week, it will face earth.. If the magnetic field again becomes unstable, then signifi
cant solar flares can be emitted
