- Full night session (9.8 hours)
Session operated with remote monitoring for first 3 hours.
- Main aim of the session was to test automated SharpCap imaging capture and integration with AstroMain /PHD2 and acquire selection of targets - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 1°C (min)

LAMOST-HVS1 is the first hypervelocity star (HVS) discovered from the LAMOST spectroscopic survey (Zheng et al, 2014, see report ) . It is a B-type star with a heliocentric radial velocity about 620 km/s, which projects to a Galactocentric radial velocity component of ~477 km/s. With a heliocentric distance of ~13 kpc and an apparent magnitude of ~13 mag, it is the nearest bright HVS currently known. With a mass of ~9Msun, it is one of the three most massive HVSs discovered so far. The star is clustered (taken from report abstract )
