А вот и циркуляр! Гена, официальные и категоричные поздравления! Electronic Telegram No. 3584Central Bureau for Astronomical TelegramsINTERNATIONAL ASTRONOMICAL UNIONCBAT Director: Daniel W. E. Green; Hoffman Lab 209; Harvard University; 20 Oxford St.; Cambridge, MA 02138; U.S.A.e-mail: cbatiau@eps.harvard.edu (alternate cbat@iau.org)URL http://www.cbat.eps.harvard.edu/index.htmlPrepared using the Tamkin Foundation Computer NetworkCOMET C/2013 N4 (BORISOV) Gennady Borisov, Crimean Laboratory of the Sternberg AstronomicalInstitute, reports the discovery of a comet on three CCD images taken with a0.2-m f/1.5 astrograph on July 8.99 UT, the object displaying a coma ofdiameter about 20"; the initial astrometry is tabulated below. A. Novichonokadds that ten follow-up 180-s exposures taken by I. Ionov with the Crimean0.32-m f/4 Newtonian reflector on July 11.0 show a large, diffuse, roundcoma of diameter 1'.7 and total mag near 13.5 but with no visible tail.After posting on the Minor Planet Center's NEOCP webpage, other CCDastrometrists have also noted the object's cometary appearance. P.Birtwhistle (Great Shefford, Berkshire, England; 0.40-m f/6 Schmidt-Cassegrainreflector; July 12.1) finds a central condensation of diameter 6" surroundedby a faint coma of size 25" x 35" (and total mag 15.2), elongated in p.a.135/315 degrees; the magnitude was 15.2 as measured in an aperture of diameter34" and 16.1-16.5 as measured in an aperture of diameter 12".8. Four stacked60-s CCD exposures taken by E. Romas, V. Nevski, O. Zelyoniy, and A. Porfir'evwith a 0.25-m reflector at the ISON-Kislovodsk Observatory in Russia on July11.99 show a coma of diameter 2'. H. Sato (Tokyo, Japan; remotely using aniTelescope.net 0.51-m f/6.8 astrograph located near Mayhill, NM, U.S.A., onJuly 12.46) found a bright, strongly condensed coma of diameter 1'.0 withV-band magnitude 12.9 as measured within a circular aperture of radius 32".8;images taken on July 13.4 as on the previous night by Sato show similarappearance, but the magnitude was 13.9 in the same-sized aperture. R. Ligustri(Talmassons, Udine, Italy; remotely with a 0.50-m f/4.5 reflector ofiTelescope.net located near Mayhill) noted a coma diameter of about 16" intwilight. K. Kadota (Ageo, Saitama, Japan; 0.25-m f/5 reflector; July 12.77;through clouds) finds a coma of total mag 13.5 and diameter 0'.6 with no tail. A. Hale, Cloudcroft, NM, U.S.A., reports total visual mag 13.5(corrected for atmospheric extinction) with a diffuse 0'.6 coma as seenvaguely at low altitude with a 0.41-m reflector on July 12.44. 2013 UT R.A.

Еще раз всем огромное спасибо за поздравления!Пока просто не хватает времени всем лично ответить. Как ненормальный продолжаю наблюдать , да еще момент открытия совпал с мероприятием "Южные ночи"Мы все вместе погрузились в этот процесс. Поисковую задачу веду на матрицу FLI PL16803, любезно предоставленную Игорем Молотовым ( надеюсь, что она так и останетсяу меня ). Блинкую вручную ( тяжкий труд ) ( с учетом поля зрения и светосилы телескопа) и тоже мечтаю немного автоматизировать эту часть работы (Вадим Саваневич обещал помочь ) . Прошлой ночью тоже искал, но до обработки руки пока не дошли Надеюсь, что через пару - тройку дней я войду в нормальный режим и смогу быть на связи.Всем тоже удачи!Геннадий.
