M1.5 solar flare with CME, glancing blow possible?

An M1.5 (R1-minor) solar flare erupted this morning which peaked at 01:45 UTC. Sunspot region 2887 was the source of the eruption.

The solar flare produced Type II and IV radio sweeps which was a sign that the event is eruptive and launched a coronal mass ejection into space. Due to the location of sunspot region 2887, the bulk of this CME is heading well west and south of our planet. The CME does however have a partial halo outline of about 220 degrees as seen on SOHO/LASCO so a glancing blow can not be fully ruled out.

The NOAA SWPC and SIDC both expect a glancing from this eruption early with the latter expecting the cloud to arrive early on Thursday, 4 November. If the cloud really does pass our planet, we doubt we will see storm conditions (Kp5 or more) but it might be something to look out for if you are a high latitude sky watcher.
