Solar cycle 24 sunspot

A second sunspot of solar cycle 24 popped up on April 13, 2008.

On April 12, in MDI magnetograms, an area with a typical solar cycle 24 magnetic configuration became visible at a high latitude near the east solar disk boundary in the northern hemisphere (picture on the left). Small coronal loops were formed in the corona above the area with the concentrated magnetic field. On April 13, a sunspot was formed at the photospheric level: a tiny cycle 24 spot visible in the picture on the right. Both pictures were taken by MDI onboard of SOHO. Some activity coming from this region was noticed by Nemo, a software for automated detection of eruptions. Several eruptive dimmings were detected.
