June '25

Session Schedule
22:00 in English
10:00 pm and 11:30 pm in Portuguese

 

  • July 10th - Full Moon

  • July 24th - New Moon - second session in the days around is the best period to observe the Milky Way.

  • The Milky Way is clearly visible during both sessions.
    For good observation, days without a Moon in the sky are recommended (between the waning and waxing quarters, preferably as close to the New Moon as possible).

  • July 17 marks the beginning of the Perseid Meteor Shower activity period, which will last until the end of August, with the peak of activity occurring on the night of August 12-13.

  • July and August mark the period of the year when we have the greatest variety of objects to observe in the sky, namely colorful stars like Albireo, star-forming nebulae like the Swan and Lagoon nebulae, open star clusters like Messier 11 and NGC 457, globular star clusters like Messier 4 and, most importantly, the famous and spectacular Great Hercules Cluster!!
