The sunspot count has not been this low for many years. I wonder if the sunspot count on spaceweather for the years 2009 and 2010  are using the old sunspot count method or the new method.

Blank again.....yet I see two spots (one yesterday & one today) that aren't counted? In the past I've seen much smaller spots that HAVE been counted?!

New method, as far as I can remember.

I guess they don't make the threshold - you must have better eyesight than me, as  I can't see any spots!

I have been looking at past sunspot count archive records on spaceweather.com, there is no annual number of sun spotless days for 2008. In their archive records for December 30 2009 they have 260 days of spotless days.  In  the new adjusted method that appears on the present page the number is 51 days.  The archives records has 2010 with a massive 486 days which is lower than on the home page of 260 days. I wonder what would the current number of sun spotless days this year would be if we were still using the Wolf method.

486 days in a year ? Am I missing something?

It will be interesting to see what the polarity is of the latest spot. I read somewhere the last spot had reversed polarity which would indicate the start of the next cycle! Hope that's not the case.....

Hopefully, @Yarmy will be able to tell us.

Are we talking about 2706 that just rotated onto the east limb?

20180420_053000_512_HMIB.jpg

 

It's an SC24 group. The white indicates positive magnetic field lines emerging from the Sun, and the black indicates negative field lines where they go back in (so to speak). The pattern is reversed in the Southern Hemisphere (black to the left, white to the right). It's also very low latitude which is the other indicator that it belongs to the current cycle. SC25 spots in the Northern Hemisphere will have black to the left, and white to the right, and will start appearing at higher latitudes.

The new small sunspot that has appeared in the Southern Hemisphere is notable because it has reversed polarity. What does that mean? Well, it could mean it belongs to SC25, or it could just be an anomalous group for SC24. On average, something like 3% of all sunspot groups exhibit reversed polarity.

The first reversed polarity sunspot of SC24 arrived in late 2007, yet 2008 and 2009 both had more than 250 spotless days so it doesn't preclude a long, drawn out minimum even if it is an SC25 spot.

 

 Just thought I’d quote these from  a previous discussion on this since we are back on the subject.

Spaceweather.com has not updated the sunspot count today.

I have went to the Solarham.net website and they said that there are currently no visible sunspots for the first day of May.re

Spaceweather also updated now and we are spotless for the 3rd consecutive day.

The total for this year so far is 70 days.
