Bjorn Granslo, Norway has kindly extended the sequence issued on Early Warning Circular 184 and CSN 0126 to accommodate the fading of the object to near magnitude 11, although oscillations are continuing. A Finders format chart has been issued on CSN 0127 and will appear in graphical form on the TA website shortly. Further details of the extended sequence appear below: *** Sequence Stars *** Id R.A.
