The group has just returned from the 2023 expedition to Mount Teide and the Parador. We have already booked next years trip back to the Parador and the wonderful staff who really our stay comfortable.

BAA Comet Section Meeting (8/7/2023)
A group of us recently attended the British Astronomical Association (BAA) Comet Section Meeting. This was held at the fantastic Greenwich Maritime Museum and organised by the Flamsteed Astronomical Society (FAS).
Start | End | Speaker | Subject |
---|---|---|---|
09:00 | Doors Open | ||
09:30 | 09:45 | Nick James (FAS) | Welcome From BAA & FAS |
09:45 | 10:15 | Walk to Greenwich Planetarium | |
10:15 | 11:00 | Planetarium (Meteors & Comets) | |
11:00 | 11:30 | Walk from Planetarium | |

13:45 | 14:15 | Jonathan Shanklin | Comet Analysis |
14:15 | 14:45 | Thomas Lehmann | Comet magnitude estimation using AIRTOOLS |
14:45 | 15:15 | Robin Leadbeater | Dissecting Comets using Spectroscopy |
15:15 | 16:00 | Break | |
16:00 | 16:30 | Dr John Mason | Comets & Meteoroid streams |
16:30 | 17:30 | Prof. Alan Fitzsimmons | Exocomets |
17:30 | 18:00 | Closing discussion |
Following the introductions the group walked up the Greenwich Observatory Planetarium for a presentation. Unfortunately even though the resident astronomer did an interesting talk, the comfy chairs, lack of sleep and early start meant quite a few eyes started to close !
All the talks were informative ranging from Helen’s talk on her outreach efforts working with schools and enabling the students to submit their comet observations and as a result being cited on publications. The talks on Comet analysis, estimating magnitudes to the techniques and equipment used to perform spectroscopy on the coma, ion tail and dust tail.
The final section of talks was covered the charismatic Dr John Mason talking about predicting the future meteor storm intensity based on the earth passing through different dust clouds of past comet passes.
Professor Alan Fitzsimmons talked about the recent efforts and discoveries made on exocomets using new observatories like TESS and JWST.
Our gratitude goes to the BAA, Flamsteed Astronomical Society and the fantastic Greenwich Museum staff for providing us with a great day.
Hopefully at some point in the near future the talks will be found at the BAA’s Youtube channel.
Tenerife 2023 Expedition Booked
So BASEG have recently booked our flights and hotel accomodation for our Tenerife 2023 Expedition. We now have a grand total of 11 participants and as long as the world does not have a repeat of global ‘Human Malware’ epidemic or a deranged lunatic doesn’t try to blow the world up then we will going to Mount Teide for Astronomy/Astrophotography.
Quite of few of the group have been purchasing Harmonic Mounts (ZWO/Pegasus) in an attempt to reduce their travelling weight. It will be interesting to see what scopes are used on the mobile mounts …. interesting times.
Member attends ORION open evening, Oak Ridge (USA)
One of our members recently attended an open evening lecture on 19th September 2018 hosted by ORION (Oak Ridge Isochronous Observation Network) at the Roane State Community College in Oak Ridge, Tennessee.
The meeting was attended by a broad range of ages including a group of high school students studying Astronomy.
The guest speaker was Mark Uhran who is currently employed at the local Oak Ridge National Laboratory in the ITER fusion reactor initiative. Previously Mark has spent 28 years working with NASA on design, development and operation of the ISS. He retired from NASA headquarters in 2012 at the conclusion of the station assembly phase having completed his last 7 years as ISS Division Director.
His hour long lecture entitled “Human Space Exploration: The Merits of Avoiding Gravity Wells!” discussed the current US plan of placing future habitable orbital platforms at known Lagrange points before 2030.
The main reason to using the Lagrange points is that maintaining position and moving between these points takes little to no fuel at all especially when using ION drives.
The Lunar Lagrange platform would be habitable allowing it to function as a jump point to targets further afield such as a mission Mars. Another advantage of the Lunar Lagrange point is being able to observe the activities of other nations on the dark side of the Moon.
He also went on to discuss the use of private companies and emerging technologies that will to be needed to be employed in order to fulfil the project goals in a timely and cost effective manner.
One interesting point was the recent change of US policy to allow the use of Nuclear Fission reactors (U235) rather than radiothermal generators (RTG) that utilise Pu238 such as those used for the Cassini mission. The rationale behind such a decision is due to the energy output boost of fission reactors. This would allow the the outward journey time to Mars to be reduced from 300-150 days (depends on planetary positions) to 30 days. This would vastly reduce the effect of the potentially life threatening radiation on the human crew.
There is an open conference in Oak Ridge October 23-25th entitled “The TVIW Power Of Synergy Space Symposium” to promote safe, fast, and affordable human development of the solar system.
ORION also have regular public observation meeting at Tamke-Allan Observatory in Rockwood, Tennessee on the first and third Saturday of the month. The facility has an indoor classroom with available toilet facilities.
BASEG member articles in Astronomy Now
Two articles written by BASEG members have been published in the September 2018 edition of Astronomy Now and includes images by another member :
- Observing In Paradise
- The Solar System In One Night
BASEG Member Published Article In Astronomy Now
BASEG member Mark Radice has written an article entitled “The Star Party survival guide” which was accepted by “Astronomy Now” and is available in the August 2018 edition.
He also publishes useful videos on his YouTube channel.
Tenerife9 2018 Session Ends Early – Saharan Dust Stops Play
The group has had to bring the session to an early close due to the Saharan dust levels wiping out the sky quality. Known as the Calima, hot winds from the East bring Saharan dust across to Tenerife which destroys the sky quality needed for deep sky imaging.
We monitored the SONG (Stellar Observations Network Group) weather page throughout the week to assess our chances at clear sky imaging. When the red level is breached then the resident telescopes at Teide close their domes. For our purposes we were looking for dust levels around 0.001 which is below the yellow line.
Before the Calima arrived the SQM was measured to be around 21.68 mag/arc sec2 (Bortle class 4) compared to around 20.5 (Bortle class 4/5) in the UK local area. Bob’s image also shows the visible layer of Calima dust :
It was a good week for all regardless of the common issues many of us encountered that stopped initial imaging attempts but once into the groove some nice images started to appear both for the portable deep sky imagers and those using the Mons Telescope for spectroscopy and lunar/planetary imaging (Mars/Jupiter/Saturn/Neptune/Uranus).
We would like to extend our gratitude to the IAC for allowing us to the use of the Mons Telescope and the associated facilities ….. gracias amigos 🙂
Planning for Tenerife9 – 2018 Trip
A bunch of us are planning a trip to the astronomical facility at Mount Teide sometime in the summer 2018.
