You project the image of he sun on to a white card placed in front of the eyepiece of a telescope or monocular. Point the scope at the sun WITHOUT looking through it and move the card until you see the Sun's disc. Unfortunately the Sun is very quiet at the moment which is puzzling solar astronomers since there are hardly any spots on it's surface.
PS The transit of Venus can be studied with this arrangement and is going to reoccur in a couple of years time I think
Galileo. He was the first to study the sun and he got blind by looking at it for long.
The study of sunspots began back in 1609 by Galileo. Galileo noticed the sunspots while gazing through a telescope. The actual study did not commence until 1612.
In a blind study, the participants do not know which treatment they are receiving, while in a double-blind study, both the participants and the researchers do not know which treatment is being administered.
If you want to study graphic arts, you can do it without going to college. However, your only option for achieving a job in this field is only by going to college.
Yes, sunspots can be seen from Earth without a telescope if viewed with proper eye protection during a solar eclipse or by using solar viewing glasses during a transit of the Sun. However, for regular observation, a telescope with a solar filter is recommended to safely observe and study sunspots.

Blind observation refers to observing a phenomenon without any preconceived notions or biases influencing the process. In the context of research, blind observation means collecting data without knowing the purpose of the study or the expected outcomes. This approach is used to reduce potential biases and ensure data is collected objectively.
He used it to study the moon, Jupiter's moons, Saturn, Venus and the sunspots on the sun.
a single blind study or a case study?
Sunspotting is the activity of observing and tracking sunspots on the surface of the sun. Sunspots are dark, cooler areas on the sun's surface caused by intense magnetic activity. Tracking sunspots helps scientists study solar activity and predict space weather.
In a single blind study, the subject being studied does not know whether he is part of the experimental group or control group, but the researcher recording the results does know. In a double blind, neither the subject nor the observer knows to which group in the experiment the subject belongs.
