  The ap­proach for the align­ment of Sir­ius is the use of portable co­or­di­nate metrol­ogy in­stru­ments in a com­mon ref­er­ence, via a net­work of sta­ble points pre­vi­ously sur­veyed. This type of net­work is com­posed of a dense dis­tri­b­u­tion of points ma­te­ri­al­ized in the form of em­bed­ded tar­get hold­ers on the spe­cial slab and ra­di­a­tion shield­ing. Phe­nom­ena such as ground move­ments, tem­per­a­ture gra­di­ents and vi­bra­tions could lead to mis­align­ment of the com­po­nents, pos­si­bly caus­ing a degra­da­tion in ma­chine per­for­mance. There­fore, the rel­a­tive po­si­tions of the ac­cel­er­a­tor mag­nets need to be pe­ri­od­i­cally ver­i­fied along with the struc­tures sur­round­ing it to en­sure a good ref­er­ence to fu­ture align­ment op­er­a­tions. This paper will pre­sent the sta­tus of Sir­ius mon­i­tor­ing sys­tems, in­clud­ing data from the first months of op­er­a­tion of the hy­dro­sta­tic lev­el­ling sen­sors. Also, pos­si­bil­i­ties with sim­pli­fied net­work mea­sure­ments for de­tect­ing struc­tural de­for­ma­tions and as­sess­ing its sta­bil­ity will be pre­sented, along with a pro­posal of a pho­togram­met­ric re­con­struc­tion of the align­ment pro­file of the stor­age ring. Fi­nally, it will be shown a com­pi­la­tion of analy­sis on the de­for­ma­tion of the Sir­ius fa­cil­i­ties.
