Data analysts on duty : M. Fraser, D. Wright, A. Pastorello

Time shared with Benetti Large Program (BLP) over the third three nights rather than the breakdown of firewalled nights - this was due to RA pressue ranges of targets and having to work around the weather. Data reduced, as much as possible with the PESSTO pipeline

Total time spent BLP on 20120826 : 3.5h

Total time overall in Aug 2012 : 34h (out of total of about 75hr clear)

Total time lost on 20120826: 0h

All times CST and approximate 19.05 start 19.10 STD EG274 gm11+gm16 (blk flt) +gm13 + gm13 (blk flt) seeing~0.6 19.30 SN2011hp R band follow-up BLP seeing~1.0 20.05 SN2012dh gm13+UBVRi BLP followup Nice spectrum, S/N~100, there are both Ba II and Sc II around 6200A. Plateau phase, nothing uncommon. seeing~1.0 20.48 Switch to PESSTO 21.15 SN2012ca Ugriz follow-up seeing~0.6 21.30 PESSTO classification: 21.31 LSQ12eit, after 60s of exp it was not visible, maybe due to a combination of high airmass, moon and magnitude of the object. 21.35 SSS120814:221352-124146 gm13. Used PESSTOEFOSCPHOT. Best match with several Ia 10d-12d after maximum light. z~0.08. seeing~0.6-0.7 21.54 PSN J21015899-4816259 already classified as young Ia. Looking for a confirmation as request in the target page. Best match with several Ia close to maximum light (in range from -4 to +3, but best match with the maximum light). Redshift z~0.018 as the host galaxy. seeing~0.6 22.10 LSQ12elt gm13. Used PESSTOEFOSCPHOT Best match with several Ia at ~10d post maximum lights. z~0.1 seeing~0.5-0.6

22.30 SN2012dy gm13+UBVRi PESSTO follow-up Greta S/N, slightly different from the previous sub-run at 6500A, no significative evolution form the previous one. Temperature decreased respect the previous sub run. seeing~0.5

23.00 SN2009ip gm13 + UBVRi BLP followup seeing~0.5

23.50 LSQ12egy gm13 + UBVRi PESSTO follow-up in order to have better S/N seeing~0.6 00.55 photometric std pg2336 UBVRigrz seeing~0.5 01.00 SSS120810:231802-560926 UBVRi PESSTO follow-up seeing~0.5

01.20 PSN J23054871+1419564 gm13 PESSTO classification Best match with some Ia 91T-like at -4d from maximum light. z~0.11 seeing~0.5

02.10 SN2011iv gm13+BVRi BLP follow-up seeing~0.5

03.35 LSQ12elj gm13 PESSTO classification. Uncertain detection, the coordinate of LSQ point between to objects. Could be another Ia at +20d. z~0.09 seeing~0.9 Sporadic clouds

04.05 SN2012ec gm13+Ugriz PESSTO follow-up Good spectrum, the Sc II and the Ba II at about 6200 appear weaker than in other IIP, as for HeII/NaID. seeing~0.8 04.35 LSQ12dlf UBVRi PESSTO follow-up seeing~0.6

04.50 LSQ12emi gm13 PESSTO classification Best match with Ic 1994I close to maximum light. z~0.05 seeing~0.5 05.10 Crash of the interface because of the target was too close to the zenit 05.55 PSN J02554120-2725276 gm13 PESSTO classification Best match with Ia 91bg-like at maximum light and z~0.02 seeing~0.5 06.10 END OF THE AUGUST RUN
