主題: AAVSO Special Notice #318: SN 2012hr, a Type Ia supernova prior to maximum 作者: peter 於 2012-12-24 10:26:06 AAVSO Special Notice #318: SN 2012hr, a Type Ia supernova prior to maximum http://www.aavso.org/aavso-special-notice-318 SN 2012hr was discovered by Colin Drescher (Calamvale, QLD, Australia; Backyard Observatory Supernova Search (BOSS)) on 2012 December 16.53. The object was discovered at a red magnitude of 14.8. Subsequent spectroscopy by Milisavljevic et al. and Morrell et al. on December 19-20 indicate this object is a Type Ia supernova about one week before maximum light. The object is well-placed outside of the majority of galaxian light of the presumed host, PGC 18880. See CBET 3346 (D.W.E. Green, editor) for more details. The object will likely be slightly brighter than 14.8 at the time of publication of this Special Notice. Use of photometric filters is strongly encouraged by CCD observers, so that light curves may be more easily calibrated. The supernova is located at the following (J2000) coordinates: RA: 06 21 38.46, Dec: -59 42 50.6 A sequence is available for this supernova, and may be plotted using AAVSO VSP: http://www.aavso.org/vsp Please report all observations as "SN 2012hr". This AAVSO Special Notice was prepared by M. Templeton. --------------------------------------------------- SUBMIT OBSERVATIONS TO THE AAVSO Information on submitting observations to the AAVSO may be found at: http://www.aavso.org/webobs SPECIAL NOTICE ARCHIVE AND SUBSCRIPTION INFORMATION A Special Notice archive is available at the following URL: http://www.aavso.org/special-notice-archive Subscribing and Unsubscribing may be done at the following URL: http://www.aavso.org/observation-notification#specialnotices Page Editor: Matthew Templeton Last Updated: December 23, 2012 - 4:56pm 主題: 回覆: AAVSO Special Notice #318: SN 2012hr, a Type Ia supernova prior to maximum 作者: 曹大貓咪 於 2012-12-24 11:35:10 又發現一顆超新星...

還是有計劃巡天在比較.. 主題: 回覆: AAVSO Special Notice #318: SN 2012hr, a Type Ia supernova prior to maximum 作者: 吳柏賢 於 2012-12-24 17:05:05 當然是有計劃巡天在比較的阿
