Sunspot 2192 got flared up with an X-class flare this Sunday. I received a notification of this flare on my iphone app 'Solar Monitor' when i was about to put Lunt 152 Solar Telescope on CGEM DX mount. My excitement got flared up as well!

Solar flares are the explosions on the sun, which can cause disturbances here on earth. X-class is a a very big explosion which can initiate radio blackouts on the sun facing side of earth. This was a X1-class solar flare.
