Interesting question. The solar event of 1859 was called the Carrington event after Richard Carrington..however I am having trouble locating info for the storm 154 prior to this...I found some small info in popular science ..the date they used for the maximum storm was 1706..however...
The least known amount of solar activity occurred in the year 1871.
1705
The least known amount of solar activity occurred in the year 1871.
The factors of 1705 are: 1, 5, 11, 31, 55, 155, 341, and 1705.The prime factors of 1705 are: 5, 11, and 31.
Examples of solar activity include solar flares, sunspots, coronal mass ejections, and solar wind. These phenomena can have effects on Earth's magnetic field, technology, and space weather.
Solar flares are ejected from the Sun every so often. It relates to solar activity on the Sun. They can occur at any time, but are more common at the peak of the cycle of solar activity and for about 3 years after the peak. The solar activity cycle takes about 11 years.
The solar activity cycle, which includes the solar maximum and solar minimum phases, lasts about 11 years. This cycle correlates with the flipping of the Sun's magnetic field every 11 years. This is known as the solar magnetic activity cycle.
The average solar cycle length is approximately 11 years, though it can vary between 9 to 14 years. This cycle is characterized by fluctuations in solar activity, including sunspots, solar flares, and coronal mass ejections. The cycle consists of periods of increasing solar activity, known as solar maximum, followed by decreasing activity, called solar minimum.
Sunspot activity is closely related to other forms of solar activity, such as solar flares and coronal mass ejections (CMEs). The presence of sunspots indicates areas of intense magnetic activity on the Sun's surface, which can lead to the release of energy in the form of solar flares. These flares and CMEs often occur in conjunction with sunspot cycles, as both phenomena are influenced by the Sun's magnetic field dynamics. Thus, sunspot activity serves as a key indicator of overall solar activity and its potential impact on space weather.
Sunspots themselves do not directly increase the solar wind; rather, they are associated with solar magnetic activity. However, sunspots can lead to increased solar activity, such as solar flares and coronal mass ejections (CMEs), which can enhance the solar wind. During periods of heightened solar activity, the solar wind may become more intense and variable, impacting space weather conditions on Earth.

The cycle of maximum and minimum solar activity, known as the solar cycle, typically repeats approximately every 11 years. During this cycle, the sun undergoes periods of increased sunspot activity (solar maximum) and decreased activity (solar minimum). The duration can vary slightly, ranging from about 9 to 14 years. This cycle influences solar phenomena, including solar flares and coronal mass ejections.
