obvious oval shape with a bright core located between Bootes and Hercules. Approx

Jupiter Moon Venus Conjunction
22nd/23rd Feb 2023
Sitting about 4 degrees either side of the crescent Moon with Jupiter uppermost and
brighter Venus the conjuction was quite a spectacle.

Venus will approach Jupiter until on the 1st March they will be only 38 arcmins apart.
25th/26th Feb 2023
The first aurora seen in 2023.
A noticeable glow along the northern horizon when imaged showed a band of green

Acitivty was noticeable by eye despite a bright Moon images as always showed the
more subtle movement.
The show was ended by cloud moving in about 1am.
The Sun is very active this year so potentially good for auroras.
26th/27th Feb 2023
In the last few days there was a large fast CME which arrived early sparking a bright
even visible to the south coast of the UK.
The event was stilll showing on magnetometers all through the next day.
Right behind was a larger explosion which triggered even brighter aurora on 27th/28th.
But UK was mostly clouded out.
