Réalta i réaltbhuíon an Mhíl Mhóir a ndearnadh taifeadadh uirthi den chéad uair i 1596, ach a aithníodh mar réalta athraitheach i 1638. Fathachréalta dhearg a athraíonn le tréimhse 331 lá ó mhéid 10 suas go dtí 2. Bhain sí méid 1.2 amach i 1779, i measc an 20 réalta is gile sa spéir. Is í an chéad shampla de réaltaí ar leith iad athraithigh Mira, réaltaí athraitheacha fadtréimhseacha le tréimhsí chomh fada le míonna nó níos mó.
