Variable star V603 Aql - 13.5.2021 at 01.00 - 13.5.2021 at 05.30 Fregenal de la Sierra, Espanja Observation number 98382

Visibility II / V

Tapio Lahtinen, Tampereen Ursa

I participated in the AAVSO campaign for the first time.
From this the wish collapsed in an email so I directed my Spanish tube to the constellation of Kotka and photographed the subject for 4.5 hours with 30 second exposures.
I sent the results to AAVSO and the results will be shown here (hopefully shown).

I also made my own curve and it shows in the picture.

Melko kaaoottisen näköistä käyrää.

Piti oikein googlettaa. Kyseessä valkoinen kääpiötähti jonka kumppani ilmeisesti punainen kääpiötähti. Kiertävät hyvin lähellä toisiaan. Kiertoajaksi Wiki sanoi n. 3h 20min.

Hyvännäköinen käppyrä. Tosiaan aktiivinen tähtipari.
