Registration & Payment

The conference registration closed on April 17, 2024. As there was a high demand (pressure factor > 2), please, do not make any travel plans until you receive an acceptance.

The regular fee deadline is August 2 (due to several requests, it has been extended until this date). Do not pay the registration fee before your participation is accepted.

Reduced fees are available for astronomers and students from less privileged countries.

Payment of the regular registration fee is open through the paypal/pix from the Brazilian Astronomical Society (SAB – Sociedade AstronĂ´mica Brasileira). Once the payment is made, send us the receipt to iaus395@iag.usp.br (please, write “receipt” in the subject).

Brazilian residents should pay through the chave pix (CNPJ da SAB) 53757191000105 (students pay a regular fee of R$975 and others R$1270).

Participants from abroad can pay through the paypal buttons below. Unless you are LOC/SOC/invited, do not pay the fee before your work is accepted. In case you have trouble, send an email to iaus395@iag.usp.br (please, write “payment problem” in the subject).
