Liverpool Telescope Calls for Proposals for Semester 2018A
Calls for Proposals have gone out from the PATT, LJMU and CAT TACs for observations commencing in Semester 2018A (1 Jan 2018 → 31 Aug 2018 inclusive). The deadline for submission of proposals is 17:00 GMT on Tuesday, 3rd October 2017. Applicants must use the new version (v0.7) of the application form and the new method of submission. Full details of these and the calls for proposals from all three TACs can be found at [this link to the full story].
LT at June 2017 Cosford Air Show
Last month the National Schools' Observatory and the Liverpool Telescope held an exhibition in the "Space Hangar" at the 2017 Royal Air Force Cosford Air Show. A news article about this event is now on the Liverpool John Moores University news site. The LT exhibit featured scale models of the Liverpool Telescope, plus its proposed 4 metre diameter successor Liverpool Telescope 2. [full story]
Spectacular pictures added to LT Picture Gallery
An album of over seventy spectacular pictures made from LT data has just been added to the LT Picture Gallery. The pictures were made by taking archived greyscale IO:O data that had been observed through effectively red, green and blue filters, and combining them in various ways to produce colour images. This skilful post-processing was performed by Swedish amateur astrophotographers Göran Nilsson and Wim van Berlo. [full story]
New Filter for RISE
[UPDATE (26 July): The filter has now been changed] The RISE fast-readout camera is having its "V+R" filter replaced with a 720 nm long-pass filter on 26th July 2017. This is being done to enhance the capabilities of the camera with regard to measurement of exoplanet transits around late-type, red dwarf stars. More details can be found in the "Filter" section of the RISE instrument page.
Quicker Daily Data Flow and Weekend Data Releases
Changes to LT data handling procedures now mean that new science data are being distributed to observers between 09:30 and 10:30 UTC on the morning after they were observed, seven days a week. We hope this will further enhance the LT’s effectiveness for time domain astrophysics. See the full news article for discussion of how this will affect your research.
SPRAT pipeline upgrade
The LT's SPectrograph for the Rapid Acquisition of Transients (SPRAT) recently got flux calibration added to its Level 2 pipeline. This will prove to be very useful for LT users performing the transient classification work that SPRAT is regularly used for.
LT tracks rare microlensed quasar
In a great illustration of the power of LT's long term monitoring capabilities, the
Gravitational LENses and DArk MAtter (GLENDAMA) team
has been conducting optical monitoring of about ten gravitationally lensed quasars with the LT since 2005. The
light curves of double quasar SDSS J1339+1310 have recently been published (Goicoechea and Shalyapin, 2016)
and show a time delay of 47 days between the source images, and interestingly
also reveal different microlensing along the two light paths. [full story]
