 abstract of observational proposal
It is well accepted that the small-scale solar activities play important roles in heating the upper solar atmosphere, including the solar chromosphere and the solar corona (Li et al. 2007; Schmieder et al. 2013; Wang et al. 2014). Detailed study of the response of the upper solar atmosphere to small-scale flux emergence and the related changes of physical parameters will open a new window to investigate the heating mechanisms of the upper solar atmosphere. In this proposal, we would like to observe small-scale solar activities, such as small-scale emerging flux region (SEFR), Ellerman Bombs (EBs), jets, coronal bright points (CBPs) with the Interface Region Imaging Spectrometer (IRIS) together with Hinode and New Solar Telescope (NST) at Big Bear Solar Observatory (BBSO) in order to investigate the physical properties, spectroscopic characteristics and evolutions of these activities.

 remarks
Dates: 2016 August 19 to 21 in order to coordinate with BBSO/NST
1 day for minimum number of observation days
It is not necessary for observations to be on consecutive days, but eac observational sequence should be uninterrupted.

Time window: 16:00-23:00 UT, short interruptions are allowed

Target(s) of interest: The target would be any active and quiet regions on the solar disk, which is possible to produce small-scale activities such as small-scale emerging flux region (SEFR), Ellerman Bombs (EBs), jets, coronal bright points (CBPs)
