Yes , the AAVSO American Association of Variable Star Observers is based in the United States . There are also contributing observers from other countries . I suspect that both U . S . and international observers might manage to make some observations on the 23 rd through the 25 th . I don ' t know if it is possible to post observations while the site is ' closed '. I tend to doubt it . The last data points I see at the moment are late on the 22 nd , U . S . time . It seems pretty likely that data taken on the 23 rd , 24 th , or 25 th could be submitted to the AAVSO on or after the 26 th of November . <| sep |> In California , all semiauto centerfire rifles will have to be registered as assault rifles after the first of the year , and will become nontransferable , but not rimfires . Do you have a source ? I wasn ' t aware of any further restrictions being enacted .
