According to a report posted to the VSOLJ mailing list by Iijima-san in Asiago, Italy, T CrB was measured at about 7 mag as of 21:00 UT on September 4, suggesting that a nova eruption might have begun.

If confirmed, time series as long as possible is recommended.

You are welcome Jerry.

Your contribution to ARAS database (JDH) is very appreciated.
