- Attempted Night Session (2.7 hours total) . - Main aim of the session was to test the operation and use of a Pegasus Motor Focus Unit that was newly installed onto the TS 80mm f6 APO secondary scope - Opportunity was taken to acquire images of an open cluster and a couple of comets     - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature:  5.5°C (minimum)  - CCD Temperature:  -20°C (66% av. power) - Notes from 2018-11-30 >>

LAMOST-HVS1 - Hyperveolocity (HV) Star

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
