  It is known that the weak state of the heliosphere due to diminished solar
activity in cycle 24 back-reacted on coronal mass ejections (CMEs) to make them
appear wider for a given speed. One of the consequences of the weak state of
the heliosphere is that more CMEs appear as halo CMEs (HCMEs), and halos are
formed at shorter heliocentric distances. Current predictions for the strength
of solar cycle (SC) 25 range from half to twice the strength of SC 24. We
compare the HCME occurrence rate and other properties during the rise phase of
cycles 23, 24, and 25 to weigh in on the strength of SC 25. We find that HCME
and solar wind properties in SC 25 are intermediate between SCs 23 and 24, but
closer to SC 24. The HCME occurrence rate, normalized to the sunspot number, is
higher in SCs 24 and 25 than in SC 23. The solar wind total pressure in SC 25
is ~35% smaller than that in SC 23. Furthermore, the occurrence rates of
high-energy solar energetic particle events and intense geomagnetic storms are
well below the corresponding values in SC 23, but similar to those in SC 24. We
conclude that cycle 25 is likely to be similar to or slightly stronger than
cycle 24, in agreement with polar-field precursor methods for cycle 25
prediction
