Nova N CAS 2021 - 1.7.2021 at 07.10 Fregenal de la Sierra, Espanja Observation number 99282

Visibility III / V

Tapio Lahtinen, Tampereen Ursa

AAVSO received an email alert that a nova has been detected in Cassiopeia and more observations are needed.
Therefore, the Spanish telescope on it to take a series of images and measurements.

R 7.13
G 7.71
B 7.65

As you can see from the observations, the red area is clearly the brightest, as you can see from the picture.

At its brightest, the nova was visible to the naked eye.
And now the observations have revealed a new clarification.
Quite an interesting case, as this story shows.

Nova is in a very good location next to the bubble mist and from Finland it might be noticeable because it is so bright.

Note, the picture was taken as early as June 30. but no photometric observations could be made of it because the star burned through the lights for 10 seconds.
