Just looked at a timelapse from the evening  20th January 2016 that I recorded and it looks as though I have caught  bit of an auroral display that I haven't even noticed before. In the bottom right. above the tree.

Wow that TCI is dropping fast. That’s the lowest it’s been in this minimum. Only 0.77 to go to beat the record. 

 Not updated today.

I wouldn't be certain but you would expect at this time of year for it to rise slightly or be stable and not drop as it is at present

Wonderful, notching up that percentage.

Looking quarterly for trends we have bounced around a little the last 18 months but I think Q1 at 65% is currently the mark to beat.

Why is that 'wonderful', SB?

It doesn't make any sense to compare calendar years because solar cycles are never exactly 11 years long. The last 5 durations going backwards from SC23 were:

SC23: 12 years 4 months

SC22: 9 years 11 months

SC21: 10 years 6 months

SC20: 11 years 5 months

SC19: 10 years 6 months

And even then the definition of duration is somewhat arbitrary, being based on the 13 month smoothed mean (which itself can be calculated in various ways: Meeus, etc), and maxima usually have 2 distinct peaks, etc, etc.

This is a better method for comparing progress:

Or better still, ignore spotless days, and concentrate on the smoothed monthly SSN.

Just a short-lived (and very faint) SC24 spot on the 22nd:
