We report further analysis of MAXI/GSC GRB 110213B (GCN #11716).
The refined position of the GRB is

(R.A., Dec) = (+41.61 deg, +1.19 deg) = (02 46 27, +01 11 14)(J2000)

with a rectangular 90% statistical error box with the following corners:

(R.A., Dec) = (+41.62 deg, +1.11 deg) = (02 46 29, +01 06 23)(J2000)
(R.A., Dec) = (+41.53 deg, +1.18 deg) = (02 46  7, +01 10 48)(J2000)
(R.A., Dec) = (+41.61 deg, +1.27 deg) = (02 46 26, +01 16  2)(J2000)
(R.A., Dec) = (+41.70 deg, +1.19 deg) = (02 46 48, +01 11 37)(J2000)

Without assumptions on the source constancy,
we obtain a rectangular error box with the following corners:

(R.A., Dec) = (+41.40 deg, +0.87 deg) = (02 45 36, +00 52 14)(J2000)
(R.A., Dec) = (+41.31 deg, +0.94 deg) = (02 45 13, +00 56 41)(J2000)
(R.A., Dec) = (+41.75 deg, +1.42 deg) = (02 46 59, +01 25 10)(J2000)
(R.A., Dec) = (+41.84 deg, +1.35 deg) = (02 47 22, +01 20 45)(J2000)

There is additional systematic uncertainty of 0.2 deg (90% containment radius).
