POLARIMETER DEVICE PROJECT

[Joan Guarro Flo]

Hello,

From the village Horta de Sant Joan, a possible good place for observing the 2026 total solar eclipse,
I sent you these pictures from the last few days.

You can see the Mars Theta angle variations.​ And also, the Polarimetric software allows the
Instrumental Theta Error to be subtracted from TheGiver observations.

Cheers, J.Guarro

Hello,

You can see a reference star HD103287 and the variable V CVn observations, and the interesting views of
comparing their spectrum and polarization.

Cheers, J. Guarro.

Hello,

You can notice these coherent results of V CVn on 2025 06 028.

Regards, J. Guarro.

Hello,

These are Del Sco and P Cyg last night.

Regards, J. Guarro.

Hello,

New observations and new answers to learn.

Cheers, Joan.

Hello,

Despite the weather, I can observe from time to time.

You can see these changes of intensity in V CVn.

Cheers, J. Guarro.

Hello,

A star studied spectroscopically for many years is VV Cep.

Its spectropolarimetry data says something, one only needs to understand why.

Cheers, J. Guarro.

Hello,

This is what I could take last night from Pallas, it is on the boundary to take "comfortable" observations.

This is the result of 4 x 800 sec integration séries, for 0, 22,5, 45, and 67,5 degrees positions, 12800 seconds in total.

Regards, J. Guarro.

Hello,

You can see that whereas Pi Aqr, as the other Be stars, shows stable % Polarization and Theta Angle levels, P Cyg has oscillating values on their ones.

Cheers, J.Guarro.

Hello,

Another spectroporatimeter could be The-Maid, simpler and cheaper than The-Giver, and with great dynamic range.

Cheers, Joan.
