Sunspot AR2699 on the 9th February 2018
GROWING SUNSPOT: Sunspot AR2699 continues to grow, more than doubling in size since it appeared on Feb. 4th. This image from NASA's Solar Dynamics Observatory shows the sunspot as compared with the size of the Earth:
The sunspot has developed an unstable "beta-gamma" magnetic field that harbors energy for M-class solar flares.
NOAA forecasters estimate a 15% chance of such explosions on Feb. 9th. Free: Solar Flare Alerts.
With two primary dark cores larger than Earth and a scattering of moon-sized magnetic condensations stretching more than 100,000 km across the surface of the sun, AR2699 is an easy target for backyard solar telescopes.

My Image below was taken with a 127mm refractor telescope using a Canon 700D camera fitted and a 2x Barlow lens, a glass solar filter was attached to the front of the telescope lens for safe viewing and imaging of the Sun.
I also use a HEQ5 Pro mount for tracking.
