Relating the Start to the Terminator of Solar Cycle 25 and a Significant
X-Flare Event
Abstract
After analyzing the lowest adjusted 10.7cm solar flux values, we find
that the adjusted flux for October 2019 is low enough to locate the
start of Solar Cycle 25 between August 2019 and January 2020. Further
findings point to November-December 2019 as the starting date for Solar
Cycle 25, while the 2K high (based on 2048x2048 pixels SDO images)
resolution sunspot number points to December 2019. Once we understand
the signal for the start of Solar Cycle 25, we can deduce the start of
the time frame for the ‘Terminator’. This is the moment when Cycle 25
will be ‘fired up’. Two recent articles made headlines using complex
mathematics to predict the start of the ‘Terminator’. However, at the
time they didn’t know the start of Solar Cycle 25 and therefore failed
in their effort. The reason for this is that the low point between
cycles is currently considered unimportant. We strongly disagree and
point out that we can calculate the ‘Terminator’ more accurately if the
low is considered a crucial starting point. A possible significant solar
flare event in excess of X10.0 could happen in 2021.
