We present highly sampled photometry of the supernova (SN) 2023ixf, a Type II SN in M101, beginning 2 days before its first known detection. To gather these data, we enlisted global Unistellar Network citizen scientists. These 252 observations from 115 telescopes show SN's rising brightness associated with shock emergence followed by gradual decay. measure peak $M_{V}$ = -18.18 $\pm$ 0.09 mag at 2023-05-25 21:37 UTC agreement previously published analyses.
Abstract First detected on 2023 November 4 by the Gravitational-wave Optical Transient Observer, SN 2023wrk is a Type Ia Supernova at 40 Mpc, with significant unburned carbon in outer ejecta. In this note, we present photometric and spectroscopic observations analysis conducted Global Rapid Advanced Network Devoted to Multi-messenger Addict over 115 days period, which includes 78 of measurements. The were contributed both amateur professional astronomers. J. Liu et al. analyzed physical...
We present a coordinated campaign of observations to monitor the brightness James Webb Space Telescope (JWST) as it travels toward second Earth-Sun Lagrange point and unfolds using network Unistellar digital telescopes. Those collected by citizen astronomers across world allowed us detect specific phases such separation from booster, glare due change orientation after maneuver, unfurling sunshield, deployment primary mirror. After sunshield on January 6 2022, 6-h lightcurve has significant...
