Will this launch use the PSLV-XL?

Will this launch use the PSLV-XL?

In my humble opinion, yes.

Given launch mass of only 900kg it should be a CA (Core alone) variant. However isro may choose to go for a XL variant anyways.

Gunter: Is that direct information, or deduction?  (I copy/paste/sent this post to Gunter with my question.)

(The previous thought or consensus was that NovaSAR-S and SSTL-S1 4 were launching with multiple secondary payloads.  Some or all of those payloads are now manifested on PSLV C43.)

SSTL Signs a Launch Agreement with the ISRO's Antrix Corporation

Quote
Surrey Satellite Technology Ltd. (SSTL) has signed an agreement with Antrix Corporation Limited, the commercial arm of the Indian Space Research Organisation (ISRO), for the launch into a 580 km. SSO of NovaSAR-1, a small, Synthetic Aperture Radar (SAR) satellite, and SSTL S1-4, a high resolution Earth observation satellite the two satellites will launch on PSLV-C42 and is scheduled to lift-off in September of 2018.

Quote
NovaSAR-1 is a technology demonstration satellite mission designed to test the capabilities of a new low cost S-Band SAR platform.  The spacecraft was designed and manufactured by SSTL, with an S-Band SAR payload developed by Airbus Defence and Space in Portsmouth, UK, and an Automatic Identification Receiver (AIS) receiver supplied by COM DEV to track ships at sea.  NovaSAR-1 will be operated from SSTL's Spacecraft Operations Centre in Guildford, UK.

I got this as direct information from an insider of the Indian space program - but i have until now not found a second independent or official confirmation.

Isro chairman K Sivan told TOI, "We are going to conduct 19 missions, including 10 satellites and nine launch vehicles, between September and March. For Isro, this will be the highest density period for launches as never before we had launched two satellites within 30 days consecutively for months.

We will resume our services on September 15 with the PSLV C42 mission, which will totally be a commercial launch." PSLV C42 will carry UK satellites - Novasar and S1-4 - as the main payload.

NOTAM is out!

1) So, launch would be NET September 16, at approximately 16:30 UTC?

2) Does the daily launch window fill the entire NOTAM time length--approximately 4 hours?

3) Could someone plot the NOTAM quadrangles on a map, please?

4) We should see some satellite processing or launch vehicle imagery soon?

1. Yes launch is NET September 16th - Exact time is not set in stone yet

2. Most likely not. Most PSLV missions have launch window of around 20 minutes.

3. A more detailed NOTAM will be released closer to september 16th only then will accurate plotting be possible

4. Launch campaign pictures/video should be released around a week before launch

ISRO will launch PSLV-C42 on September 16th at 10.07pm
https://telugu.samayam.com/latest-news/india-news/isro-will-launch-pslv-c42-on-september-16/articleshow/65739252.cms

IST = UTC + 5:30

22:07 IST = 16:37 UTC, which makes a good match to the NOTAM.

EDT = UTC - 4.00
       = 16:37 UTC - 4.00
       = 12:37 AM

Launch Time is on September 16, 2018 at 12:37 PM EDT
