OUR BIG STAR


We are doing this project to find out the velocity of the rotation of the Sun by looking at the sun spots.


The ivestigation is important because it lets up know things about  the Sun that we didn´t know before.We like to  resolve the problem about who much time it takes the Sun to rotate once  around it self.our first hypotesis was false.
We are going to share  a link about the data that we get.

We use these elements. :
Four photographs in which the Sun apeard wiht some spots . these spots we moving in the diferent photos.A Solar templete to calculate the sopts more acuretely.We use the app microsoft excel that we had  calculate by looking at the Sun spots.


We do this  procedure: has taken .

we checked how long it takes the spot to moved acording to the images.
we aded all the days it put in the images to know how long it takes teh spots to moved around X distance.

We have looking how long it takes the sspots bny the image It puted the days We calculate by the sun spots ( for example if the spot takes 2 days in going acroos nçand this distance was 5 cm and the other spot also was 5 cm .It takes the same that the first spot) and we add it to, the previus.
this was only a half of the Sun , so if we multilpicated , by 2, to konow ,the 2 face , in fact all the Sun.
the magnitudes are this (time , space, and the velocity ) to know , how takes the sun to rotate  once around it self we count with 4 photo, that are from the satelit SOHO , we use Excel app to getthe datas of the tale and know how much spaceand that it´s going acroos we get ,calculate the time and the long thanks to the stencil that they give ass.
This is the resultate:

in the velocity table we observe that according to the near the poles spots it took less and  if they were near the Ecuador it tooks less time to rotate once.
In the table of the space we saw that in the space was between one of the spots allways wasn´t the same distance.

The objetive of this investigation it´s lograted because  we lograted calculated the time that takes the Sun to rotate once around it self by the solar spots.
Our hypothesis was false because we puted that the Sun took less 101 years to rotate once around it self when realty it tooks  between 25 and 36 days to do that.
When we make this investigation we found some datas that we 
didn´t know that it was true ,for example that the Sun spots doesn´t moved in the same way, in the velocity in the recorrated in the solar superfice . 
And because of that some parts of the investigation were complicated but in finnally we lograted our objetive.
