What is smoothed sunspot number?
The 13-month smoothed monthly sunspot number is derived by a “tapered-boxcar” running mean of monthly sunspot numbers over 13 months centered on the corresponding month (Smoothing function: equal weights = 1, except for first and last elements (-6 and +6 months) = 0.5, Normalization by 1/12 factor).
What is the current sunspot number?
|10.7cm Solar Radio Flux||84||-5|
What does the sunspot number indicate?
The sunspot number index R is a measure of the area of solar surface covered by spots. As the number of spots increases and their magnetic complexity grows, they become likely sources of large eruptive energy releases known as solar flares.
What is the average number of sunspots?
Yearly Mean Sunspot Numbers
How many sunspots will there be in 2025?
The Solar Cycle 25 Prediction Panel predicted in December 2019 that solar cycle 25 will be similar to solar cycle 24, with the preceding solar cycle minimum in April 2020 (± 6 months), and the number of sunspots reaching a (smoothed) maximum of 115 in July 2025 (± 8 months).
How many sunspots will there be in 2022?
Predicted Sunspot Number And Radio Flux
|Date||Sunspot Number Predicted||10.7 cm Radio Flux Predicted|
Why do sunspots move?
As the sunspots are a result of magnetic processes in the Sun, they move in the direction of its magnetic field lines. As shown in Figure 9 the Sun’s magnetic field lines are extended parallel to the Page 14 equator and become twisted. Therefore, sunspots move mainly parallel to the equator.
How long do sunspots last on skin?
Healing can take from 10 to 21 days. Chemical peels. An acid solution applied to sunspots causes the skin to eventually peel away so that new skin can grow. Chemical peels may cause a burning sensation that lasts a few minutes and can be painful.
Which year had the highest average number of sunspots?
Solar Cycle 24 reached its maximum – the period when the Sun is most active – in April 2014 with a peak average of 82 sunspots. The Sun’s Northern Hemisphere led the sunspot cycle, peaking over two years ahead of the Southern Hemisphere sunspot peak.
Do sunspots make it hotter on Earth?
Sunspots have been observed continuously since 1609, although their cyclical variation was not noticed until much later. At the peak of the cycle, about 0.1% more Solar energy reaches the Earth, which can increase global average temperatures by 0.05-0.1℃. This is small, but it can be detected in the climate record.
How many sunspots will there be in 2023?
Predicted Sunspot Number And Radio Flux
|Date||Sunspot Number Predicted||10.7 cm Radio Flux Low|
How does the NOAA predict the sunspot number?
Navigation: Low-frequency navigation signals degraded for brief intervals. Multi-year forecast of the monthly sunspot number and the monthly F10.7. Predicted values are based on the consensus of the Solar Cycle 24 Prediction Panel. Multi-year forecast of the monthly sunspot number and the monthly F10.7.
Where does the International sunspot number come from?
These relative sunspot numbers are now designated Ri (International) instead of Rz (Zurich). The international sunspot number is produced by the Solar Influences Data Analysis Center (SIDC), World Data Center for the Sunspot Index, at the Royal Observatory of Belgium. We kindly request that you acknowledge the SIDC when using these data.
Is the sunspot number related to the ionospheric index?
The daily sunspot number has little, if any, relationship to ionospheric variability. However, the most widely used Ionospheric Index, R12, is derived from the daily sunspot numbers. The R12 index is a twelve-month smoothed relative sunspot number.
Is the R12 index the same as the sunspot number?
Smoothed Sunspot Number. The daily sunspot number has little, if any, relationship to ionospheric variability. However, the most widely used Ionospheric Index, R12, is derived from the daily sunspot numbers. The R12 index is a twelve-month smoothed relative sunspot number.
