Subject: Request for Digitized 1987-1989 Blackburn Fajr/Isha Observation Records
|
|
|
|
Assalamu alaykum wa rahmatullahi wa barakatuh,
|
|
|
|
My name is Ali Camarata. I am a researcher working on an open-source project to build a comprehensive dataset of verified Fajr and Isha twilight observations worldwide.
|
|
|
|
Hizbul Ulama UK conducted pioneering observation campaigns in Blackburn (53.748 N, 2.480 W) during 1987-1989, recording actual Fajr and Isha times through direct human observation. These observations, referenced in academic literature and in Mufti Shabbir Ahmad Sahib's guidance, represent some of the earliest systematic dawn/dusk observation records in the UK.
|
|
|
|
I currently have 10 records from these observations (6 Fajr, 4 Isha) based on dates cited in secondary sources (Asim Yusuf's "Shedding Light on the Dawn" and related publications). However, the original observation log likely contains hundreds of individual dated records.
|
|
|
|
Would it be possible to obtain a copy of the full observation log from the 1987-1989 Blackburn campaign? I am interested in:
|
|
- Each observation date
|
|
- The recorded Fajr time for that date
|
|
- The recorded Isha time for that date
|
|
- Any notes on sky conditions
|
|
|
|
Even a photocopy or photograph of the handwritten log would be helpful. I can digitize it.
|
|
|
|
This data would be historically significant as one of the earliest systematic Fajr/Isha observation campaigns in the UK, and would contribute to ongoing research that benefits the Muslim community's understanding of prayer times at northern latitudes.
