[vsnet-chat 3364] Preliminary sequence for QW Ser

["Bruce Sumner" <b.sumner@bom.gov.au>]

Here is a quick preliminary sequence for the currently bright UG star 
QW Ser. It is based on Arne's one night photometry, but, as Arne 
stated, it should be good to about +/-0.02 magnitudes. This sequence 
will be updated when Arne obtains more data. Enjoy.

Notes:

1. There is a brighter star in this field not measured by Arne. 
Details from Tycho-1 follow (Tycho-2 not currently accessible):

    15 26 24.9  +08 21 52   161  229      9.6            0.5 

2. It is quite likely that stars 1 and 2 are saturated, resulting in 
magnitudes and colours that may be accurate to only 0.2 magnitudes or 
so. This will be confirmed when this sequence is updated.
