Neste Sunday, May 3, 2026, the Terra natural satellite reaches its full phase, presenting 97% visibility for observers in the southern hemisphere. Lua will remain in this configuration until the 9th, when the transition to the waning phase begins. Dados of Instituto Nacional of Meteorologia confirm the astronomical phenomenon that marks the first stage of the May lunar cycle.
Cronograma complete phases in May
The month of May 2026 records five lunar phase changes, distributed as follows:
- Lua Cheia: May 1st at 2:24 pm
- Lua Minguante: May 9th at 6:13 pm
- Lua Nova: May 16th at 5:03 pm
- Lua Crescente: May 23rd at 8:12 am
- Lua Cheia: May 31st at 05:46
Maio has a rare feature: two full moons in the same month. The first occurred on the first day, while the second will take place on the 31st, ending the lunar cycle practically within the monthly period. Este phenomenon occurs because the average lunation lasts 29.5 days, allowing two full cycles to fit into the 31 days of May.
Compreendendo the lunar cycle
A lunation, also called a lunar cycle, represents the time interval between two consecutive new moons. Esse period varies subtly, maintaining an average of approximately 29.5 days. Each Durante cycle, the satellite goes through four main phases, each lasting approximately seven days.
Além of the main phases, there are interphases that characterize gradual transitions. Entre to Lua Nova and Cheia, Quarto Crescente and the Crescente Gibosa phase appear. Entre to Cheia and Nova, the Minguante Gibosa and Quarto Minguante phase occur. Essas subdivisions allow for more accurate observations of lunar behavior throughout the month.
Full phase Detalhes
In the full phase, the Terra is positioned between the Sol and the Lua, an alignment that allows the lunar side facing the planet to receive full illumination. Este is the moment of maximum luminosity, when Lua appears on the horizon exactly at the moment Sol sets. Visibility of 97% this Sunday reflects almost the entire surface reflecting sunlight.
Fase waning approaches
Seis days separate the current moment from the next change. On May 9, at 6:13 pm, Lua enters a waning phase, when its luminosity gradually decreases night after night. Durante At this stage, the amount of visible illuminated surface progressively reduces until it returns to Lua Nova. The Quarto Minguante marks the midpoint of this transition.
Significado in astronomical observations
Cada lunar phase has distinct observable characteristics that make it easier for those interested in astronomy to follow the cycle. Lua Cheia offers the best conditions for detailed photographs of the satellite, although its intense luminosity makes it more difficult to observe nearby less bright celestial bodies. Observadores amateurs use the lunar calendar to plan observation sessions, considering visibility and atmospheric conditions.
