Description

It looks like today the Sun has a lot of micro-activities, like the arch shown in the previous image. In this image you will see that, even with the Ha filter kept in its center frequency, a lot of Ellerman Bombs are visible in the neighborhood of the spots. This happens in both ARs.

As you know Ellerman Bombs are considered micro-flares being normally visible in the blue wing of the Ha wavelength.
