29 marta 2003 goda v 11:37:14.67 vsemirnogo vremeni amerikanskii kosmicheskii apparat HETE-2 zaregistriroval ochen' moshnyi vsplesk gamma izlucheniya. Yarkost' istochnika byla takova, chto avtomaticheskaya sistema obrabotki dannyh prinyala ego za kosmicheskuyu chasticu, i lish' analiz v laboratorii na Zemle ukazal na istinnuyu prirodu ob'ekta. Eto proizoshlo pochti cherez chas posle registracii vspleska v gamma-diapazone.

Prakticheski srazu posle polucheniya etoi informacii opticheskoe poslesvechenie gamma-vspleska bylo obnaruzheno avstraliiskimi astronomami, kotorye smogli pronablyudat' ego cherez razryvy oblakov v usloviyah priblizhayusheisya grozy. Ob'ekt okazalsya ekstremal'no yarkim - okolo 12 zvezdnoi velichiny.

Estafetu po nablyudeniyu gamma-vspleska GRB030329 prinyali yaponskie astronomy. Oni obnaruzhili opticheskii tranzient nezavisimo ot avstraliicev, pravda nemnogo pozzhe.

V eto vremya v Amerike uzhe nastupilo utro, a v Evrope byl den'. Cherez neskol'ko chasov (5 chasov posle vspleska) k nablyudeniyam podklyuchilsya teleskop, rabotayushii v ramkah sistemy MASTER na observatorii Aleksandra Krylova v Podmoskov'e. My okazalis' pervymi v Evrope, poluchivshimi ocenku zvezdnoi velichiny vspleska v fil'tre R. GRB030329 okazalsya anomal'no yarkim dlya ob'ekta takogo klassa i imel 14-yu zvezdnuyu velichinu. My prodolzhali nablyudeniya do 01:35UT 30/03/2003. V rezul'tate poluchena krivaya bleska opticheskogo tranzienta GRB030329 v fil'tre R, privedennaya nizhe.

Cherez polchasa posle nas k nablyudeniyam prisoedinilsya rossiisko-tureckii teleskop RTT-150, a zatem v nablyudatel'nyi process stala vklyuchat'sya Evropa.

GRB030329 okazalsya pervym v istorii gamma-vspleskom, nablyudavshimsya lyubitelyami astronomii. Kak soobshaetsya v cirkulyare GCN 2010, finskie lyubiteli astronomii R. Henriksson i M. Tuukkanen proveli vizual'nye nablyudeniya opticheskogo tranzienta GRB030329 s 63-sm i 30-sm teleskopami.

Primerno do 0:00UT 30/03/2003 (12.5 chasov posle vspleska) tranzient umen'shal svoyu yarkost' po zakonu F ~ t^-1.2. Zatem oslablenie ob'ekta uskorilos' do F ~ t ^-1.9, no potom process prekratilsya, i blesk zamer okolo 17-i zvezdnoi velichiny.

Primerno cherez sutki posle vspleska byl poluchen spektr opticheskogo tranzienta na 8-metrovom teleskope VLT, i bylo izmereno ego krasnoe smeshenie, sostavivshee vsego z=0.168. Takim obrazom, GRB030329 okazalsya samym blizkim gamma-vspleskom, esli ne schitat' sverhnovuyu 1998w.

GRB030329 okazalsya unikal'nym gamma-vspleskom. Do sih por prodolzhayutsya ego issledovaniya vo vseh diapazonah dlin voln - ot radio do rentgenovskogo diapazona. V arhive GCN-cirkulyarov uzhe seichas bolee 100 telegramm posvyasheno etomu nezauryadnomu ob'ektu. Uzhe v blizhaishie mesyacy mozhno ozhidat' poyavlenie desyatkov statei, posvyashennyh GRB030329, v vedushih nauchnyh zhurnalah.

Nashi rezul'taty:

Za noch' 29/30 marta 2003 goda bylo polucheno bolee 200 izobrazhenii v fil'tre R. Nekotorye snimki byli slozheny gruppami po 4-18 kadrov dlya uluchsheniya kachestva fotometrii. Pervye kadry delalis' na svetlom vechernem nebe, a poslednie - skvoz' cirrusy nad zapadnym gorizontom, chem vyzvany bol'shie oshibki izmereniya bleska. Rezul'tiruyushaya krivaya soderzhit 64 tochki.

Rezul'taty nablyudenii s teleskopom MASTER opublikovany v cirkulyarah GCN 2002, GCN 2035 i GCN 2091.
