Vijest se pojavila na https://spaceweather.com/archive.php?view=1&day=25&month=07&year=2023, pa da ne prepričavam.
Uglavnom, očekuje se da u proljeće 2024. godine možda bude vidljiv golim okom. Sljedeće zanimljivo je neočekivana erupcija iz njegove unutrašnjosti, što mu je povećalo sjaj za 100 puta (5 magnituda). Predviđena magnituda mu je bila nešto preko 16, a poslije erupcije je promatrana magnituda dosegla 11-12. Sad opet polako pada. Trenutno se nalazi u glavi Zmaja.
