Scientists announced the start of Solar Cycle 25, signaling the end of the solar minimum, on September 15.
A magnetic anomaly on June 23 appears to be a phenomenon known as a Pc wave.
NASA said the flares may suggest the sun is emerging from the solar minimum and entering its next cycle.
The sun has been "blank" for over three quarters of the year, putting it in the running for one of the quietest periods since the start of the Space Age.
Some solar cycles feature lots of activity, while others can be relatively quiet.
Scientists predict current solar cycle will come to an end in the first six months of 2020.
Venus, Earth and Jupiter's tidal forces influence the solar magnetic field.
The sun just produced its biggest solar flare for 12 years—despite supposedly being in one of its quietest phases.
Scientists have analyzed over 30 years worth of data to find out what's going on with the sun and its unusual activity.
