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.

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.
