# TESS Program G05126 Title: Simultaneous Space And Ground-Based Flare Photometry And Spectroscopy With TESS And Amateur Astronomers PI: Jackman, James - Arizona State University Type: SMALL Summary: Coordinated multi-wavelength photometry and spectroscopy is essential for the characterisation of flares and their contribution to the high energy environments of low-mass stars. However, professional facilities are limited to a few nights of observations, limiting analysis to small samples. In contrast, amateur astronomers can observe targets for weeks and can obtain photometry and spectroscopy simultaneously with TESS, allowing us to measure the temperatures and emission line energies of larger samples of white-light flares. We propose for 20-s cadence photometry of 9 active K and M stars that can be simultaneously observed by amateur astronomers, to study and characterise these energetic events. This target list will be made public for use by our team and the wider amateur community. # Sector 056 targets observed (2 min: 5, 20 s: 3) 247985094,352.9713,19.9369,7.79,G05126;G05144;G05152;G05121;20SECONDTARGET 154101678,341.701,44.3311,7.73,G05126;G05123;G05144;G05145;G05152;G05121;20SECONDTARGET 431107890,335.0302,49.5033,7.7,G05126;G05150;G05105;G05144;20SECONDTARGET 207436278,244.2733,55.2664,8.08,G05121;G05126 219790151,264.665,61.2381,8.9,G05126;G05131 # Sector 057 targets observed (2 min: 4, 20 s: 3) 154101678,341.701,44.3311,7.73,G05126;G05123;G05144;G05145;G05152;G05121;20SECONDTARGET 431107890,335.0302,49.5033,7.7,G05126;G05150;G05105;G05144;20SECONDTARGET 435160829,346.5227,63.9258,9.06,G05121;G05123;G05126;20SECONDTARGET 219790151,264.665,61.2381,8.9,G05126;G05131 # Sector 058 targets observed (2 min: 2, 20 s: 1) 435160829,346.5227,63.9258,9.06,G05121;G05123;G05126;20SECONDTARGET 219790151,264.665,61.2381,8.9,G05126;G05131 # Sector 059 targets observed (2 min: 2, 20 s: 0) 96681015,73.9041,30.2985,9.7,G05126 219790151,264.665,61.2381,8.9,G05126;G05131 # Sector 060 targets observed (2 min: 3, 20 s: 0) 253011416,97.7537,50.0457,9.22,G05126;G05121 142439883,145.703,70.0377,8.86,G05126;G05109;G05121 219790151,264.665,61.2381,8.9,G05126;G05131
