The Sun is getting active again! We have passed through the minimum of the Sun’s 11 year cycle and solar observers have been waiting for some new activity. Well, last week we had a sunspot, now out of sight, and today 2 new spots have come into view on the ‘NW’ solar limb, see below.
The first image is a white light image which more obviously shows the spots, and the granulation of the solar surface (these are convection cells in the plasma). The second image shows a very narrow bandwidth emitted by hydrogen at 656.2 nm which shows a very different view.
ALL physical LDAS events and meetings remain postponed until further notice due to the COVID 19 pandemic.
We are, however, continuing with virtual meetings and observing sessions so we can still satisfy your interest in astronomy. Read on.
As of today, 4 August, we have had three virtual monthly meetings using the Zoom meeting software. We have also used Zoom to show objects in the sky from a remote observatory in Spain where we have access to a telescope with a camera attached. We have also observed the Sun from one of our members observatory which has a solar telescope. So, where there is a will we can use modern technology to continue pursuing our interest in astronomy. We will continue to host these events, so please watch this website and our Facebook page to be aware of them. Note that observing events are weather dependant so there is likely to be just 2-3 days notice of such an event.
Whatever the level of your interest in astronomy, welcome to Letchworth & District Astronomical Society.
LDAS is based in Letchworth, in Hertfordshire. We are a thriving society and have over a hundred members. We have people who are just beginners right through to observers with decades of experience. We have an observatory at Standalone Farm in Letchworth, and quite a few members have their own observatories too. We love to see new people come along, whatever their level of knowledge, and all are made most welcome. We hold regular meetings, star parties and other events for members and the public alike.
We can provide advice on telescopes, eyepieces, cameras or anything else you might need to satisfy your interest, just come along and ask.
We are also more than happy to present talks to clubs, schools and other organisations, and for them to visit our observatory. Talks and visits are free although donations to the society are gratefully accepted.
We invite everyone to join in our events, whenever and wherever they happen!
