Flashing shiny star

Postby Jimmyriddle » Thu Mar 17, 2016 10:09 pm

I've seen it twice this week from my flat front room window in Carlisle uk. Between 8pm and half 9, there is a flashing star I think. It would be nice to know which one it is as its a cloudy night and I can see it. Seems to be lower than other stars as the aeroplanes seem to fly around it? I'm suspicious it's a satellite but unsure. Anyone know what it is as it seems to be over the west of the city ??

Sirius, the brighest star in our night's sky is low down in the south west at around that time. The extra atmosphere it has to shine through, being low down, means it can appear to change brightness very quickly as well as show all the colours of the rainbow. It wouldn't be a satellite as they move right across the sky in just a few minutes.
I use an 11" Celestron SCT (CPC 1100) on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI1600MC and Canon 500D for imaging.

I agree! Definitely Sirius.
How can I be one with the universe when we don't know what 96% of it is.
