Any info about the Cygnus total weight, ant Antares total weight for this mission?
3,447 kg (7,600 lbs) of cargo, supplies, and equipment. Heaviest Cygnus on an Antares to date.

April 17: Launch Day
Rob Garner Posted on April 17, 2019
NASA’s commercial partner Northrop Grumman is scheduled to launch its Antares rocket carrying its Cygnus cargo spacecraft to the International Space Station at 4:46 p.m. EDT today, April 17.
Loaded with 7,600 pounds of research, crew supplies and hardware, this is Northrop Grumman’s 11th commercial resupply NASA-contracted mission. It will launch from Virginia Space’s Mid-Atlantic Regional Spaceport at NASA’s Wallops Flight Facility.
The launch, as well as briefings preceding and following liftoff, will air live on NASA Television and the agency’s website beginning at 4:15 p.m. EDT April 17.
Local and regional viewing opportunities for the launch are detailed on NASA’s website.

3,447 kg (7,600 lbs) of cargo, supplies, and equipment. Heaviest Cygnus on an Antares to date.
So we have only an approximate total weight for the entire vehicle... 1.800 + 3.447 kg = 5.247 kg

T-4hrs 32mins and COUNTING.
Teams are working through final GSE power up. Delayed on that by 10-15mins due to earlier need to shut some systems down for tests and checkouts.
Teams are continuing to work through other procedures ahead of the start of fueling.
Right now, all remains on track for a 16:46:07 EDT (20:46:07 UTC) liftoff.

So even though the launch window opens at 16:46:07 EDT, Antares teams have just confirmed that the optimum launch time today (and what they will target) is: 16:48:36.33 EDT (2048:36.33 UTC )

Oh... they're discussing a need to go back to the pad for a 5-10 minute operation. Talking about a 15-minute worse case impact to the count.

Issue with TEL will require Red Team to go back to the pad and perform ~15mins op. Launch team is still progressing with no discussed impact to launch at this time.

RF open loop and transmitter checks being done now instead of waiting as Red Team reviews procedures they'll go once they get to the pad.

My guesstimate is 3,447 + ~2,900 kg = ~6,347 kg for Cygnus with cargo at liftoff.
Perhaps this is the first Antares 230+? If not, payload looks to be near the max originally listed for Antares 230.

Red Team has COMPLETED their task and cleared the pad.
"We are good to proceed at this time."
Helium initiation in 30-ish minutes. All systems GREEN at this time!

Good question. Forgot to ask about that in interview yesterday. Will send NGIS a note to ask if this is a 230 or a 230+.
