No wind. - 23:50UT - SPECTROSCOPIC STANDARD: Feige 110: Seeing 0.9", Airmass 1.10 - 00:20UT - PHOT STD: TPHe (UBVRi): Seeing 1.1", Airmass 1.1 - 00:30UT - Focussing and image analysis SCIENCE-OBSERVATIONS: - 00:43UT - ASSASN-14kd: Classification for 300s: Seeing 1.0", Airmass 1.23 - 00:55UT - LSQ14fyc: Classification for 900s: Seeing 0.9", Airmass 1.04 - 01:15UT - SN2009ip: Follow-up in B (4x200s), V (3x200s), R (2x100s), i (2x200s): Seeing 0.9", Airmass 1.08 (+dark time). - The SNe is still visible in the acquisition images even after 800 days! - 02:00UT - SN2013hx: Deep follow-up in g, r, i: Seeing 0.75", Airmass 1.15 - The DIMM thinks the seeing is 0.6", but it's 0.75" from the images - The SNe is not in the acquisition images (even after 1 minute exposures), but these are deep images, so fingers crossed! - The seeing stays constant through the observations 0.7" at the end. - 03:20UT - ASASSN-14il: Follow-up in BVri & gm11 for 900s & gm16 and 900s: Seeing 0.8", Airmass 1.1 - 04:15UT - LSQ14gae: Classification for 900s: Seeing 0.9", Airmass 1.55 - 05:00UT - SPECTROSCOPIC STANDARD: L745a: Seeing 0.9", Airmass 1.74 (this is a terrible time to be doing STDs!) - 05:20UT - PHOT STD: TPHe (UBVRi): Seeing 0.7", Airmass 1.42 - 05:30UT - OGLE-2014-SN-073: BVRi + gm13 for 2x3000s: Seeing 0.8", Airmass 1.22 at start, Seeing 0.5", Airmass 1.2 in the middle - 08:00UT - OGLE-2014-SN-125: Classification for 600s: Seeing 0.6", Airmass 1.4 POST-OBSERVATIONS: - 08:20UT - PHOT STD: RU149: Seeing 0.6", Airmass 1.14 - 08:40UT - STANDARD: L745a: Seeing 0.6", Airmass 1.02 - 09:00UT - Skyflats: BR CERRADO POR EL NOCHE! ---- ---- SCIENCE-CONCLUSIONS: - ASSASN-14kd: CLASSIFICATION: SN Ia-91T @ z=0.027 @ -10days (SNID) - LSQ14fyc: CLASSIFICATION: SN Ia @ z=0.082 @ +10days (SNID) - ASASSN-14il: FOLLOW-UP: Lots of galaxy light in this one. SNID has issues, but super fit likes it to be a SN II @ z=0.02 @ +9. - LSQ14gae: CLASSIFICATION: SN IIP @ z=0.041 @ +6 days - OGLE-2014-SN-073: FOLLOW-UP: SN IIP @ z=0.127 @ +10 days - OGLE-2014-SN-125: CLASSIFICATION: SN IIP @ z=0.023 @ +20 days ---- ATEL SUBMITTED FOR ASASSN-14kd, LSQ14fyc, LSQ14gae & OGLE-2014-SN-125 (http://www.astronomerstelegram.org/?read=6699) |
