Powerful solar tsunami along with yesterdays impulsive M3-Class solar flare

New sunspot 1496 unleashed an impulsive M3-Class solar flare on June 3rd at 17:55 UTC. The explosion hurled a coronal mass ejection (CME) into space. The cloud does not appear to be heading for Earth, although this conclusion could be revised by further analysis.
