To the north of Arago lie two known lunar domes Arago α (termed A2) and Arago β (termed A3). These two large domes A2 and A3 belong to class D and formed during several stages of effusion, representing non-monogetic domes. The other smaller domes in Arago and Carrel show lower flank slopes (between 0.5°-0.9°). According to their rheologic properties, these low domes (A1, A4-A7 and Ca1) belong to class A implying low lava viscosities of about 103 Pa s, high effusion rates and very short durations of the effusion process of about 2–4 months. According to the classification scheme for lunar domes the domes A8 and A9 are situated between class C2 and A (due higher R415/R750 ratio), while the dome A10 is situated beween class A and E1 (principally due its small diameter, moderate average slope and high R415/R750 ratio).
 The domes A8-10 formed over a period of time of about 0.56, 0.70 and 0.90 years.
