A QUIET SUN: 4 DAYS SPOTLESS – WHAT DOES IT MEAN?

The Sun has been spotless indicating a generally very low solar activity for 4 consecutive days already. It is currently transitioning towards the solar minimum, the period in the roughly 11-year solar cycle when less solar activity is expected. This was anticipated to be reached between 2019 and 2020. Basically, the relatively cool and dark areas on the Sun’s photosphere, known as sunspots, appear and vanish due to violent twisted magnetic field interactions with its surface plasma.

THE STARS FOR ALL SEASONS

At the time of this writing, we’re approaching to the period when we experience scorching hot days in the Northern Hemisphere, when many are heading to the beach to have fun or some who stay indoors, irritated with the intense heat and chilling inside their air-conditioned rooms. We generally call this as the “summer season”. However, the proper interpretation of the season we’re in varies from where you are Earth. Specifically, only 2 (dry and wet) in the tropical regions and 4 (winter, spring, summer, autumn/fall) in the temperate regions.

THE SUN FROM THE OBSERVATORY

The Sun in H-alpha. It has been quiet, with no significant solar activity observed in the past few days except for some prominences seen in the upper and bottom portions of this image.

Note that the circular grayish spot seen on the disk (bottom left portion) is NOT something special, but an output of lens contamination.
