Aim of the project

Study of the sky: constellations, theirbrightest stars, the brightest nebulae andgalaxies in these constellations, and finallythe planets.

To estimate the activity level of the Sun

With

out any support!or help of the teacher

How to get familiar with the nightsky?

Via the Stellarium program we can get avirtual view of the sky in everywhereand whenever isneeded

How to get familiar with the nightsky?

We can identify the brightest stars of theconstellations and therefore recognize the

constellations.

Ursa Major

How to get familiar with the nightsky?

The next step is to find the coordinates ofthe interested object, just searching itsname in Stellarium.

How to get familiar with the nightsky?

We can also recognize the position of theinterested object via identification of the brightestobjects of its neighborhood.

How to get familiar with the nightsky?

We can give these coordinates to the telescope and observe the interested object.

How do we calculate the solaractivity?

We use our solar filter and filter to observethe Sun:

find a sunspotsand groups of sunspots

And finally estimate its activity level via Wolf

number , without having any information aboutthe forecast of the solar activity level : = 10 +

Where,

s is the number of individual spots,g is the number of sunspot groups, andk is a factor that varies with location andinstrumentation .

The higher is the value of R, thehigher activity has the sun!!!

The innovation The innovation of this project is that the pupil

or person who is not familiar with the sky andparticularly with the constellations and

various types of objects in them, can start tostudy the sky by his own, without anysupport, just using the laptop and theamateur telescope.

Additional innovation is that the person, whowill be interested in, could predict the solaractivity level, and therefore prevent himselffrom the peril of the enormous solar activities.
