| | | new supernova in Whirpool galaxy
Discovered in the last 40hrs by amateur astronomers in France/Germany - a supernova in M51 [Whirlpool Galaxy] below the Plough close to zenith at dusk - pretty faint for visual scopes but easy in 10s exposures via cam. My 60s shot from last below

another pic of June 3 in hi-colour saturation showing SN's typical strong blue colour and separation into RGB channels to highlight the effect  |

Nice shots,is it really 31 million years away? and does it get a name or just a number?

The supernova gets a designation from discovery date thus SN+year+2 letters beginning the year as 'A' -[Z] then 'aa'; ab'; ''ac'.... this one is 'dh' or 'SN 2011dh'.
My M51 supernova pic below from last night shows the SN is still getting brighter  . Pic via my piggybacked ETX-70 scope that's little bigger than what birders haul around but it was 'guided' on the galaxy for the 60sec exposure. My setup also on Gallery

M51 100s pic via main scope from last night in late twilight and rising full moon - both increase 'noise' so shown as negative image. SN still 'holding up' with no sign of fading  |

Wow amazing shots there nytcam! It really does take quite a bit to wrap your head around the thought that what we see now happened millions or even billions of yrs ago and what we see is the past not present.
