Science

22:41 - AT2018hla followup, seeing 1.4"
    The PI requests a galaxy spectrum. This is not SN

22:42 - Weather update
    We have a pointing restriction to the NE due to strong winds

23:21 - AT2018hyz followup, g13 1x3600s, slit 1.5", seeing 1.7"
    We adjusted the exposure time following PI's suggestion to accommodate a tight early
    night schedule and because the object is setting.
    The 1.5" slit was used due to poor seeing at acquisition image stage. Seeing has
    improved slightly, but still quite variable.

    Note: Pointing restrictions lifted at ~23:55

00:20 - Clouds rolling in, thin and wispy 🙁

00:33 - EG274 standard. seeing 1.4"

00:53 AT2019hcn classification, seeing 1.6"
    We tripled the exposure time as we feared clouds would approach.
    Note: This object is in a TESS field
    Low SNR, possible blue continuum, Ibc?

01:18 - AT2019hci classification, unable to measure seeing!
    Starting to get really cloudy. 
    I would be surprised if we get much signal from this!

01:38 - AT2019gte followup, seeing 1.6" (fluctuating quickly on DIMM, cannot measure in acquisition)

02:46 - AT2019hei classification, seeing 1.4", SN Ia

02:52 - Dome closed due to cloud cover.
