Abstract

Based on the SDO/HMI magnetograms the peculiarities of the magnetic anomaly (a small area in the sunspot umbra with reversal magnetic polarity) observed in October 21–26, 2014 are analyzed. The obtained results suggest that this feature is not the product of instrumental/algorithmic artifacts related to the SDO/HMI operation and data processing. This is a real new magnetic flux emergence in the region of opposite polarity.
