[vsnet-be 36] Delta Scorpii observations
Norwegian Astronomical Society - Variable Star Section
***** OBSERVATIONS OF DELTA SCORPII *****
The following visual observations have been made by undersigned,
during my vacation on Lanzarote:
Object YYYYMMDD(UT) Mag Obs Inst Estimates Cl
SCOdelta 20000728.94 19 GRL NE B-3;C=V;E+4 1
SCOdelta 20000730.91 19 GRL NE C=V;D+2 2
SCOdelta 20000803.91 18 GRL NE B-2;C=V;D+2 2
SCOdelta 20000805.87 18 GRL NE A-8;C=V:D+2 1
SCOdelta 20000807.88 19 GRL NE C-1;D+1 2
SCOdelta 20000809.89 19 GRL NE C-1;D+1 1
Observations are Pogson step estimates. Class (Cl) is the estimated
quality of observation: 1 = good, 2 = fair, 3 = poor. The class 2
observations were affected by haze.
Comparison stars (V magnitudes from Yale Bright Star Catalogue,
5th edition): A = 0.98 (Alpha Vir); B = 1.63 (Lambda Sco); C = 1.85
(Epsilon Sgr); D = 2.02 (Sigma Sgr); E = 2.43 (Eta Oph).
These observations confirm the brightening of this object, first
reported by S. Otero [vsnet 2034]. It is currently a Be star and
appears to be a new bright variable of the Gamma Cas type.
Observer: GRL = B. H. Granslo, Lanzarote (29 deg N, 14 deg W).
Instrument: naked eye.
Yours sincerely,
Bjorn H. Granslo
