Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 6444 is definitely OCl-1023 = Ru 132 as noted in ESO and by Brian Skiff. JH gives only an approximate position for the cluster, but calls it "A vfine L, rich sc cl of sts 12..13..m." The ESO position -- 40 seconds preceding and 2.5 arcmin north of JH's -- is good.
