What shutter speed did you use?

What shutter speed did you use? I have captured sunspots with a 1200mm equivalent lense with sun behind thin cloud back in 2004 or so. I was also worked out the sum of existing sunspots on the days my kids were born was 11. But i have no shutter speed information im afraid 😎 |

Yep, coldest weather generally appears as next cycle ramps up so we have a long way to go yet.... Guesses as to why that is true? |

Many of the tiny dots they call sunspots now would not have been counted years ago. So the sunspot number is clearly biased higher nowadays when compared to prior cycles. So when you read an article that says this solar cycle is the lowest in over a century it's really even lower than that because a century ago they did not count the smallest of sunspots like they do now.
As for why the coldest weather generally appears as the next cycle ramps up? The longest day of the year is usually somewhere around the 21st of June. Yet the hottest days of the summer for most of us in the NH are usually in August. I suspect the solar cycle is similar.

"NASA has recycled some of the language from that 2006 press release in this release on NASA researcher Irina Kitiashvili’s forecast of Solar Cycle 25 amplitude which includes this line:
The maximum of this next cycle – measured in terms of sunspot number, a standard measure of solar activity level – could be 30 to 50% lower than the most recent one.
This time it is 30 to 50% lower rather than higher which would put maximum smoothed amplitude in the range of 80 to 60. The graphics in Kitiashvili’s presentation differ from that. This graphic from slide nine has a peak amplitude of 50 with a range of 65 down to 40:" More at: wattsupwiththat.com/2019/10/29/25-for-25/

Zero indication of SC25 being a moderate or strong cycle - the opposite is true |

Since I am here, I know that some/most of my ancestors survived the Sporer and Maunder Minimums in NW England. Don't know how many cousins (or whole branches) did not make it. I am looking forward to the witch trials for the worst of the Gore-etc clan. Assuming the electricity is still on. Who knows ... but we should have a real definitive "feel" in about 5 or 6 years.  |
