TONIGHT AT BILLINGBOROUGH
Is it a good night for observing?
Astronomical observing depends on more than simply whether it is raining. Cloud cover, atmospheric turbulence, humidity and temperature can all make a significant difference to what can be seen through a telescope.
The meteoblue Seeing forecast provides an hourly view of conditions at Billingborough, including cloud cover, relative humidity, temperature and predicted astronomical seeing in arcseconds.
Seeing forecast for Billingborough
The forecast below is provided by meteoblue and is centred on Billingborough. For astronomical observing, lower cloud cover and lower seeing values are generally favourable.
Seeing describes the effect of atmospheric turbulence on the apparent sharpness of astronomical objects. Better seeing means steadier air and generally sharper views, particularly when observing the Moon, planets and close double stars.
What to look for
Cloud cover is the first thing to check. Extensive cloud will prevent observations regardless of how good the other conditions are.
Seeing is particularly important for high magnification work. The meteoblue forecast gives predicted seeing in arcseconds; lower values indicate less atmospheric turbulence.
Humidity is also worth watching. High humidity can increase the risk of dew forming on telescope optics and cameras, particularly when temperatures fall towards the dew point.
The forecast is intended as a guide. Conditions can change during the night, and local conditions at the observatory may differ from the forecast.
