Latest Solar Image 26.09.2017

Our local star the Sun has been void of much activity over the last week or two but we now see the return of the sunspot groups from a couple of weeks ago. Captured here in white light using our 80mm refractor equipped with Herschel wedge. The image was taken approx. Noon local time. False colour has been used to help the detail show.260917

Warning! Never look directly at the Sun without suitable, certified safe equipment. Sunglasses are not suitable.

Community Open Dome Event 28th Sept – Galaxies in 3D

Thursday 28th September – 7pm

The Long Eaton Astronomical Society meetings are now known as “Community Open Dome Events” and the first of this academic year is nearly here. We are joined by Professor Alfonso Aragón-Salamanca, Head of the Astronomy group at the University of Nottingham. He was an undergraduate at the University of Madrid, and got his PhD from Durham University in 1991. He worked in Durham and Cambridge for a number of years, and moved to Nottingham in 1999. His research addresses how galaxies form and evolve in different environments over cosmic time.  The topic is “Galaxies in 3D”.


“In order to understand how galaxies form and evolve we need to get very detailed information with as much spatial and spectral resolution as we possibly can. A new exciting observational technique has been developed in the last few years called “Integral Field Spectroscopy” which allows us to dissect the light emitted by different regions of galaxies simultaneously, thus obtaining three-dimensional images for them. In this talk Prof. Aragón-Salamanca will describe this new technique, its applications, and some of the most interesting results that he is obtaining within the MaNGA project, part of the Sloan Digital Sky Survey. This work is answering key questions on the formation history of the different regions and components of thousands of galaxies.”

After the talk there will be opportunity to look around the observatory and if clear do some observing using one of the telescopes housed within. Admission is via a suggested donation of £2 towards costs and includes refreshments. Talk starts at 7pm with refreshments available from 6:30pm. The event will close approx. 9pm. Under 16’s must be accompanied by an adult please.

Space Seraph – an update

On June 28th TLES launched the high altitude balloon mission “Space Seraph”. The launch was a great success with many local primary school students gathered to watch the launch prior to the annual “Eco day”.

All appeared to be going well and a predicted landing area just outside Matlock was identified. The recovery team headed off to wait near Matlock bath to await contact with the tracking devices. The landing was estimated for 11:38am, this time came and went and still no contact was made.

More accurate simulations have since been made and the average of 400 has been taken. The target area is outlined below. Search teams have since covered just under 3.5km² of the target area concentrating in an area known to be in a communication dead zone. Unfortunately nothing has yet turned up so the search continues……

Space Seraph – Race to the Heavens

The Long Eaton School are due to launch our second “near space” mission. The mission name Space Seraph was chosen by students of the school and a house competition set to design a mission patch.Space-Seraph

Launch Date: 28th June 2017. Clearance has been sought from the Civil Aviation Authority to launch a high altitude balloon at 09:35. For a period of two hours all aircraft below 5,000m will be diverted away from Long Eaton so as to prevent a collision so this really is a case of now or never, or at least for 28 days as that is the notice required by the CAA. 28th June is our school’s “Eco day” so this seemed the ideal day to look back at Earth from on high.

Mission Objectives: To launch a balloon to an altitude of 32km carrying a range of scientific experiments and a video camera. Local primary schools have been invited to join in the mission by sending in two experiments each which will be carried atop the capsule suspended beneath the weather balloon. In addition, members of the Astronomy Club will be given the chance to design some experiments too. On board there will also be a so-called Black box that will record location, altitude, acceleration, air pressure, temperature and magnetic field strength. The final piece of equipment is the GO-Pro camera that will hopefully capture the curvature of the Earth and the thin blue line that is our atmosphere.

Mission Facts: The Space Seraph mission has been funded by the Institute of Physics after a successful grant application. The mission duration is expected to be between 120 and 150 minutes. Burst altitude is estimated to be 32km. At 32km the air pressure is less than 0.7% that at sea level. The mission aims to reach more than three times the cruising altitude of a Jumbo Jet! The temperature is expected to drop below -50 degrees C. Our previous mission in 2013 aimed for 19km and reached in excess of 24km so only after we recover the data will we know how high we have managed to fly our balloon.

On The Day: We hope to bring updates as often as possible during the flight whilst we track and chase the balloon across the UK. Check back here for updates! After the event it is hoped to share a video of the entire mission in highlight format including any “You’ve Been Framed” moments from the chase team.

29th June and beyond: The Long Eaton Astronomy Society will be meeting at 7pm on June 29th where Mr M. Perkins of the school will aim to give a full mission review with some footage etc. If the weather allows there will be chance for Solar observing before hand and refreshments will be available from 6:30pm. All welcome, members free, visitors for a suggested donation of £2. After this in the following days / weeks it is hoped to publish more detailed results and data from the entire mission here on the blog.
