Flávio Bolsonaro wrote on digital networks on last Friday: "Are you going to fight for your country, or observe everything from your mobile device there on your sofa? I call on you to battle with us."
He said the vigil would be so followers could "pray for his physical condition and for the reestablishment of democratic governance in our nation."

Details of Guilty Verdict
The former president was convicted of leading a plot aimed at maintaining his control after he was defeated in the presidential race to his left-wing rival, Lula.
High Court judges said that he had knowledge of a plot which encompassed plans to assassinate the current president and his vice-presidential running mate, Geraldo Alckmin, and to detain and kill Alexandre de Moraes - the High Court judge who has been presiding over Bolsonaro's trial.
The plot was thwarted because it failed to get the support of the armed forces officials. The current president was inaugurated without problem on January 1st, 2023.
But a week later, on the eighth of January, numerous his followers stormed and vandalised official structures in the federal district, Brasília.
The law enforcement stepped in and around 1,500 people were arrested.
The magistrates found that the demonstrators had been provoked by him whose scheme, they said, was for the national armed forces to take action, bring back stability and return him to office.
At the time, his attorneys called the decades-long sentence "absurdly excessive.
He was also prohibited from seeking elected position until 2060 - eight years later after the conclusion of his imprisonment.
The ex-leader called the trial a political persecution and said it was designed to prevent him running in the next presidential race.
