I sent today my solar observation report for January 2023 to e-mail solar <at> aavso.org but after that a reply from googlemail informs:
"We're writing to let you know that the group you tried to contact (solar) may not exist, or you may not have permission to post messages to the group. A few more details on why you weren't able to post:"
Is there any problem with solar section e-mail ?
Sorry, the email account changed recently and a couple of permissions were missed. It should be working fine now. Please try again.
