Further magnitude estimates for 2010jg: Sept. 12.21, [19.4 (CSS); Oct. 17.06, 18.0 (S. Howerton, Arkansas City, KS, U.S.A., remotely using the LB-1 0.6m telescope at Rodeo, NM). The presumed host galaxy for 2010jg, SDSS J220426.80-075843.3, has redshift z = 0.061. Further magnitude estimates for 2010jh: 2009 Nov. 17.11, [18.0 (CSS); 2010 Oct. 18.20, 16.9 (J. Brimacombe, remotely with the RCOS 0.5-m telescope of the New Mexico Skies Observatory at Mt. Joy, NM). Further CSS magnitude estimates for 2010ji (whose presumed host galaxy is UGC 1230): Oct. 9.38 UT, [19.5; 28.22, 17.5.
