the Full Buck Supermoon

 


The first of four supermoons to rise in 2023, July’s lunar display will appear to be brighter in the night sky than any other full moon event that has occurred this year.


July’s full Buck Moon rises after sunset on Monday, July 3 — This is also a supermoon that will appear bigger and brighter than average.

2023 June solstice





Falling on 21 June this year, the event will mark the longest day of the year and signal the astronomical start of summer. 


A solstice isn’t a whole day. Instead, it’s a moment, when the sun is farthest north in our sky. In 2023, the solstice moment will fall at 15:57:14 on Wednesday, June 21.

first ever ranking of beneficial garden biodiversity

 




first ever ranking of beneficial garden biodiversity


1. Lichens  

2. Native ladybirds

3. Pollinators

4. Solitary bees (aculeate Hymenoptera) 

5. Sulphur tuft fungi (Hypholoma fasciculare) 

6. Slime moulds

7. Rose chafer beetle (Cetonia aurata)

8. Ink cap mushrooms (Coprinoids)

9. Hoverflies (Syrphidae)

10.Social wasps (Vespidae) 


1. Topping the list are lichens, which can often be found growing on trees or shrubs. Lichens provide food for other garden wildlife and create new habitats by providing shelter for invertebrates and nesting materials for birds and mammals.


Lichens are often associated with good air quality. They carry out photosynthesis to capture atmospheric carbon, and certain lichens also absorb atmospheric nitrogen compounds, which are common pollutants. Lichens regulate water and humidity levels by soaking up moisture during wet weather and then slowly releasing it as water vapour.  


2. Ladybirds primarily eat aphids, so have long been considered a friend of gardeners. It is said that a single ladybird can eat 50 aphids a day, or around 5,000 in a lifetime!

Country Overshoot Days 2023


A country’s overshoot day is the date on which Earth Overshoot Day would fall if all of humanity consumed like the people in that country. 




Let’s take Swiss Overshoot Day as an example. Its 2023 overshoot day is based on the latest (2018) available results from the 2022 edition of the National Footprint and Biocapacity Accounts:

Therefore, it would take (4.35/ 1.6) = 2.75 Earths to support humanity if everyone on the planet lived like the Swiss.

Earthshine tonight:

 


You may have noticed the Moon exhibiting a ghostly glow lately, where a subtle light is illuminating the usually unlit portion of the lunar surface. This is a phenomenon called Earthshine, and it can be a spectacular sight, not to mention a great opportunity for lunar photography.

Weather permitting, you can see Earthshine this evening, 22 May, after sunset (8:56pm BST in London, 8:13pm EDT in New York City).

Earthshine is visible in the mornings a few days before the new Moon, and in the evenings a few days after the new Moon. You might have already glimpsed it before sunrise on 17 May during the waning crescent phase, but if you didn’t fancy dragging yourself out of bed at that hour, we have another chance during the waxing crescent Moon phase.

Here are the next opportunities to see Earthshine:

21 May: 3.9 per cent illuminated waxing crescent Moon
22 May: 8.9 per cent illuminated waxing crescent Moon
23 May: 15.5 per cent illuminated waxing crescent Moon


What exactly is Earthshine?

Earthshine appears as a soft, subtle glow on the unlit, or ‘night’ portion of the Moon during specific phases. This is when a delicate, but somehow ghostly, shape of the full Moon is nestled in the arc of the bright crescent Moon, and it’s a beautiful sight for these early summer nights.
