CFOSAT & 7 minisats - CZ-2C - JSLC - October 29, 2018 (00:43 UTC)

[GELORD]

LT Launch time was 09:01:03 - 1069 seconds = 08:43:14 or 00:43:14 UTC

00:43:(13-14-15 ) UTC

00:43:15 lift off (my guess)

The exact time of launch of the carrier rocket CZ-2C (Y22) / Chang Zheng-2C (Y22) from Jiuquan cosmodrome: October 29, 2018 at 08:43:13, 576 BJT (00:43:13, 576 UTC). The designation of the launch mission, code - "01-97". Serial number of the launch vehicle: Y22.

I think we both agree the name is 天启 ?
The issue is not translation (the translation appears to be "Revelation" or something like that) but transliteration - how
do you spell 天启 in the Latin alphabet? The standard pinyin appears to be 'tianqi' but that's not necessarily unique and there are other conversion systems which are not necessarily better or worse.

I use this website for Chinese transliteration into English, which also gives tianqi.

Tongchuan patch says gamma-ray mission, but SpaceTy announcement says X-ray.  Which is correct?

Gamma-ray.

Actually the definitions are a bit blurry. The paper http://astro.xmu.edu.cn/__local/4/CE/12/307BD23E7942F52FF007549F1CE_C458FACB_22D1AF.pdf?e=.pdf
says the energy range is 10 to 2000 keV.   The boundary between 'hard X-ray' and 'gamma ray' I would
put somewhere around 100 keV. Others might put it higher (perhaps even 1000 keV = 1 MeV)  but certainly GRO/BATSE, arguably the classic gamma ray burst
detector, operated in a 20-500 keV energy range, so on that basis it would be traditional to refer to this mission
as a gamma-ray one.

The GRID-1 experiment on TY4-02 has its first published gamma ray burst paper: https://arxiv.org/abs/2107.10452

The paper says that the second GRID was launched on a cubesat in 2020. Does anyone know which satellite this second one was?

It's Beihang kongshi 1, launched 2020-11-06.

Thanks!  And by the way the GRID team tells me it is object 46838, so that helps with sorting out which sat is which from that launch

Thanks. So 46837 and 46839 are for Bayi 03 and Tianyan 05.

Also, I am informed that Zhaojin-1 (TY-4-02/GRID-01) is 43663
