Kak izvestno, atmosfera ochen' meshaet zemnym nablyudatelyam v optike i IK. Mozhno zapuskat' teleskopy v kosmos, no eto dorogo (hotya, "v kosmose dollar vesit men'she" B. Pachin'skii). Na Zemle stroyat sistemy s adaptivnoi optikoi (ob etom byla otlichnaya stat'ya D. Vibe v nedavnem "Zvezdochete".
Dlya otslezhivaniya sostoyaniya atmosfery primenyayut lazery (sozdanie t.n. "lazernoi zvezdy"). Ob etom i idet rech' v stat'e Tompsona i dr.

Chto mogut delat' malen'kie teleskopy v epohu bol'shih teleskopov? Eto, kstati skazat', dovol'no aktual'nyi vopros dlya nashei strany. V stat'e daetsya obzor celei i metodov togo, chto nazyvaetsya Virtual'noi observatoriei. Sovremennye informacionnye tehnologii pozvolyayut ochen' effektivno ispol'zovat' set' iz mnozhestva nebol'shih teleskopov, razbrosannyh po vsemu miru. V pervuyu ochered' rech' idet ob obzorah i nepreryvnyh nablyudeniyah (ponyatno, chto dnem-to smotret' nel'zya, a 5-6 teleskopov na raznyh dolgotah mogut pozvolit' provodit' monitoring 24 chasa v sutki, konechno na sluchai plohoi pogody neobhodimo dublirovat' instrumenty, raznosya ih i po shirote i t.d.).
Zamechu, chto eto pravil'no provodit' special'nye konferencii, posvyashennye ispol'zovaniya malen'kih teleskopov.

Obsuzhdaetsya vzaimodeistvie opticheskih i rentgenovskih nablyudenii. Dlya poiska opticheskih "dvoinikov" bol'shinstva slabyh rentgenovskih istochnikov, nablyudayushihsya na N'yutone i Chandre, nuzhna vsya mosh' 10-metrovyh teleskopov.

Nablyudeniya opticheskoi vspyshki gamma-vspleska GRB990123 s pomosh'yu sistemy ROTSE bylo bol'shim dostizheniem. S teh por prodolzhayutsya popytki povtorit' etot rezul'tat. Odnako, poka nikakih uspehov net. Potomu prodolzhayut razvivat' mat.chast'. V stat'e opisyvaetsya sistema ROTSE-III. Avtory nadeyatsya, chto ih opyt okazhetsya poleznym dlya sozdatelei analogichnyh sistem, kotorye seichas nachinayut poyavlyat'sya vo vsem mire.

Novaya professional'naya tehnika i metodika registracii meteornyh potokov. Izobrazheniya meteorov poluchalis' s pomosh'yu dvuh fotokamer s CCD-matricami. Linii, poluchennye na izobrazheniyah, ekstrapolirovalis' do ih peresecheniya. Poluchennye koordinaty radianta potoka - (pryamoe voshozhdenie = 154o.35, sklonenie = 21o.55 v epohe J2000) - horosho sovpadayut s teoreticheskimi predskazaniyami.

Na 76-metrovom radioteleskope im.Lovella observatorii Dzhordell Benk regulyarno provodyatsya nablyudeniya bolee chem 500 radiopul'sarov. Bolee chem dlya 300 pul'sarov ryady nablyudenii dlyatsya bolee 6 let (samyi dolgii - 34 goda). Po eti dannym modno opredelit' period pul'sara i ego izmenenie, a takzhe ego polozhenie na nebe s ochen' vysokoi tochnost'yu. V stat'e izlozhena tehnika obrabotki taiminga pul'sarov (momentov prihoda impul'sov k nablyudatelyu) Predlozhen novyi podhod, pozvolyayushii po vremennoi informacii pouchit' sobstvennye dvizheniya pul'sarov. Etim metodom vpervye opredeleny znacheniya sobstvennyh dvizhenii dlya 111 pul'sarov (no sami eti znacheniya v stat'e ne privedeny).

Avtor podrobno rassmatrivaet metodiku nalibrovki svetimosti cefeid v nashei Galaktike i ucheta ih mezhzvezdnogo pokrasneniya. Eti izmereniya, sovmestno s izmereniyami cefeid v galaktike NGC4258 pokazyvayut, chto tochnost' etoi kalibrovki ne huzhe 0.1m, po krainei mere dlya cefeid s solnechnym himsostavom. Razlichie v himicheskom sostave vnosit primerno takuyu zhe oshibku. Dlya togo, chtoby uvelichit' tochnost' predskazanniya svetimosti cefeid neobhodimy obshirnye raboty po izucheniyu ih metallichnosti, uchet nelineinosti v zavisimostyah period-svetimost' i period-cvet, a takzhe tochnoe opredelenie v kakoi mode proishodyat ih pul'sacii - na osnovnoi chastote ili na pervom obertone.

VLBI - Very Large Baseline Interferometry. Radionablyudeniya so sverhdlinnoi bazoi. Obychno VLBI obzorami ne zanimaetsya - nablyudayutsya izbrannye istochniki (chashe vsego - aktivnye galaktiki) v raznyh chastyah neba. Svyazano eto s malym polem zreniya (sotni millisekund dugi). V stat'e opisyvaetsya pervaya ser'eznaya popytka preodolet' eti trudnosti za schet primeneniya tehnologii nablyudenii s korotkoi bazoi, no s sohraneniem vseh dostoinstv VLBI.
