Enjoying ‘Once in a Blue Moon’ S1 noise level on HF!

See the S meter needle going all the way down to S1 when the operator releases the PTT. It quite rare these days to get such low levels of noise on HF. The default here is S9 level of noise. When I check on 160m band with 80m inverted V dipole, I get even 9+30 dB noise. What I have noted is that resonant antennas will also pick up more noise. So if I had a 160m dipole, I could have documented 9+40 dB or more of noise! I did enjoy a good ragchew with hams from Karnataka today morning on 40m, which is usually not possible with my setup.
